DOCUMENT ACTION: Proposed rule.

SUBJECT CATEGORY: Standards Governing the Design of Wall-Mounted Centralized Mail Receptacles

DATES: The Postal Service must receive written comments on or before May 21, 2004.

DOCUMENT SUMMARY: The Postal ServiceTM is proposing to replace United States Postal Service[reg] Standard 4B, Receptacles, Apartment House, Mail, which governs the design of wallmounted centralized mail receptacles whether used in commercial, residential, mixed residential, or other types of structures. The proposed standard was developed through a consensus process and was agreed to by a committee of representatives from mailbox manufacturers; mailbox distributors; mailbox installers and servicers; Postal Service customers; multiunit residential and commercial property builders, owners, and managers; and the Postal Service. Proposed provisions in the Domestic Mail Manual would provide manufacturers and customers with notice of the specifications.

SUMMARY: Wall-mounted centralized mail receptacles; design standards,


SUPPLEMENTAL INFORMATION

United States Postal Service Standard 4B, Receptacles, Apartment House, Mail, USPSSTD4B, currently governs the design of apartment house mailboxes. This standard, adopted in 1975, prescribes design limitations in terms that are no longer consistent with the operational requirements of the Postal Service. The proposed revised standard is titled United States Postal Service Standard 4C, WallMounted Centralized Mail Receptacles. The change in the title for the updated Standard, and the reference to the equipment as ``wall mounted centralized mail'' receptacles rather than ``apartment house mail'' receptacles are made solely to reflect that the Standard applies to receptacles in a variety of residential and commercial buildings, and not only ``apartments.'' Adoption of the proposal will not result in any change in Postal Service policies concerning the purchase of this delivery equipment or the provision of delivery equipment for Postal Service customers previously in effect under STD4B.

Under the Postal Reorganization Act, the Postal Service is responsible for the maintenance of an efficient nationwide system for collecting, sorting, and delivering of mail. 39 U.S.C. 403(b)(1). Customer mail receptacles are an important consideration in this system. Receptacles should offer measurable protection for mail. This system benefits both senders and addressees who rely on the Postal Service to deliver intact mailpieces. In addition, the design of receptacles should not present any potential safety hazards to carriers. Finally, a welldesigned receptacle can be accessed and serviced quickly by carriers, which helps to reduce Postal Service costs.

As noted above, the current standard for mail receptacles in apartment and commercial buildings was adopted more than a quarter century ago, in 1975. The Postal Service and its customers have changed considerably during that time. In particular, there have been significant changes in the volume and type of mail received by many customers, with the average customer receiving more pieces on a daily basis and often largersized pieces. Postal Service statistics indicate that, since 1985, flatsized mail volume has increased by 47 percent and parcelshaped mail volume has increased 42 percent. Receptacles that were adequate to support the daily volume of mail in earlier years cannot easily hold many customers' mail today. As a result, delivery is less efficient since carriers must take extra time to prepare (i.e., fold or bend) the mail in order to insert it into customer receptacles. The mail may inadvertently be marred as a result of this effort. Accordingly, the proposed changes, as described more fully below, provide for larger receptacles than the minimum sizes in the current standard. The proposed sizes are intended as minimum standards. Buildings may provide larger sizes to accommodate the needs of their tenants, and it is expected that manufacturers will offer a wide range of products to meet customer needs

In addition, the proposed changes generally require the provision of some larger shared receptacles, usually referred to as parcel lockers, based on the number of units in the building. These receptacles will not be assigned to specific residents, but will be used for the delivery of mail matter that, due to size or quantity, cannot be placed in the receptacle assigned to the addressee. This system obviates the need for the Postal Service to redeliver the mail or for the addressee to pick it up at a Postal Service retail facility. Postmasters shall consider excusing buildings from the need to provide parcel lockers if they have an agreement in place, as is the case with some commercial and residential buildings, for an alternative type of parcel delivery (e.g., concierge service or acceptance at the building management office), or if they provide receptacles for tenants that exceed the minimum size requirements and can accommodate parcels.

Additionally, mail security has become a growing concern of the Postal Service. Statistics collected by the Postal Inspection Service demonstrate that theft of the mail is a growing problem. From 2000 to 2002, Postal Inspection Service statistics indicate that reported attacks on wallmounted boxes increased from 988 in FY 2000 to 2,819 in FY 2002. Moreover, it does not appear that these attacks are limited to a particular region of the country, but are occurring in different areas. In any event, even if the number of incidents had remained static, mail security would still be an area of concern since identity theft has become one of the motives for mail theft and this crime has potentially devastating financial impact on victims. The current generation of receptacles is not well suited to provide adequate physical security in this environment. According to a report issued by the Federal Trade Commission on September 3, 2003, a recent survey indicates that 27.3 million Americans have been victims of identity theft in the last 5 years, with 9.9 million victims in the last year alone. The reported cost of these crimes last year was $53 billion, affecting both businesses and individuals, with an average loss of approximately $5,000. Although stolen mail accounted for only 4 percent of these crimes, the Postal Service is seeking means to reduce the effectiveness of these attacks on our customers as much as possible. Accordingly, as explained below, the proposed revised Standard includes features to significantly improve the security of the receptacles.

Based on these concerns, the Postal Service determined to review the existing Standard for wallmounted receptacles to determine if improvements were possible. It determined to use a consensus process in developing the proposed revised Standard. In a consensus process, representatives of interests that would be substantially affected by a new rule meet as an advisory committee and negotiate among themselves and with the agency to reach a consensus on a proposed new rule.

In this instance, the Postal Service retained the services of an independent, neutral third party to convene a Consensus Committee and facilitate discussions of committee members. Based on the convener's recommendation, the Postal Service invited interested parties that were expected to be substantially affected by the new rule to become Consensus Committee members. Further, committee members were responsible for representing other interested individuals and organizations that were not present at committee meetings and keeping them informed of the committee's proceedings.

As part of the ground rules agreed to by all members of the Consensus Committee, the Postal Service agreed to use a recommendation by the committee as the basis for the proposed rule. In addition, each private member of the committee stipulated that, if it agreed to a recommendation by the committee, it would support that recommendation [[Page 21457]]
and the proposed rule except to the extent that it does not reflect the recommendation. As part of its process, the Consensus Committee held several meetings that were open to the public. The committee has also agreed to meet, either in person or by teleconference, approximately 6 and 12 months after publication of the Final Standard, to discuss any implementation or other issues that arise after adoption of the new Standard.

In all, twenty parties were members of the committee. The Committee members were as follows: Academy Mailbox Company, Inc.; American Eagle Mailbox Manufacturing Company; American Locker Security Systems; Associated Building and Contractors, Inc.; AuthFlorence Manufacturing Corp.; Bommer Industries, Inc.; Building Owners and Managers Association International; Compx Security Products; Direct Marketing Association; HSS Industries; Jensen Industries; Magazine Publishers Association; National Association of Home Builders; National Association of Housing and Redevelopment Officials; National Association of Realtors; National Multi Housing Council/National Apartment Association; Parcel Shippers Association; Postal Products Limited; Salsbury Industries; and the United States Postal Service.

Each member of the committee, except one, signed the final agreement and agreed to the Final Committee Standard that is the basis for this proposed rule. The other committee member, National Association of Home Builders, although not a signatory to the agreement, stated that it was in substantial agreement with the requirements except with respect to parcel lockers. The proposed standard defines the new delivery equipment design requirements and other approval process requirements that must be met in order to receive design approval from the Postal Service. It is not intended to provide a private right of action or otherwise serve any nonpostal purposes.

The following table compares requirements of the proposed standard, which shall be titled USPSSTD4C, to the old standard, USPSSTD4B, and the modified version of USPSSTD4B, which shall be referred to as STD4B+ (refer to the STD4B+ description provided later in this section):

Requirements.

Although not included as part of the revised Standard, the Consensus Committee also considered other issues related to the implementation of the new Standard, if it is adopted. These concerns include the types of properties whose receptacles are subject to the new Standard, the dates by which affected buildings must comply with the new Standard, and the conditions under which existing buildings must replace receptacles with boxes meeting the new Standard. In considering these issues, particularly the latter two, the Postal Service and Committee members were mindful of conflicting concerns. That is, there is a need to weigh the benefits that would be realized from the installation of receptacles meeting the new Standard against the potential costs this would impose on building owners. Additionally, the effective date of the changes needs to be consistent with the ability of the construction industry to include the new receptacles in new structures.

The committee did not attempt to conduct a formal costbenefit analysis in considering these questions. In many instances, the assignment of precise amounts to the benefits and costs was considered a difficult task. Nevertheless, throughout the meetings, committee members identified a number of benefits and costs that would occur from the promulgation of Standard 4C. Building owners/managers, their tenants, persons and firms corresponding with the tenants, and the Postal Service are expected to realize benefits from the installation of Standard 4C receptacles. The receptacles will accommodate larger volumes of mail and different size pieces, and minimize consequences incurred by pieces during delivery to smaller receptacles. Tenants will have more flexibility in using the boxes to hold mail, particularly during days when they may be away. The receptacles will also provide increased mail security. They will more easily be served by carriers, increase service efficiencies, and facilitate earlier delivery. The new receptacles should reduce maintenance costs incurred by building owners, and may result in cleaner, less cluttered lobbies. The provision of larger receptacles and parcel lockers will allow tenants to avoid the need for trips to their Post OfficeTM to pick up mail. It may also allow some building owners to reduce office staff, particularly in buildings that provide such staff to receive parcels addressed to tenants.

The costs are not necessarily limited to the costs of the receptacles and their installation, but could also include the costs of modifying buildings to accommodate the increased size of receptacles under STD4C. These costs will be incurred by building owners and, indirectly, by their tenants. Although the committee did not develop a firm number for the cost of Standard 4C receptacles, two of the manufacturers on the committee estimated the cost would be 15 to 30 percent more than STD4B receptacles.

Under the agreement reached by the Consensus Committee, the provisions of Standard 4C would apply to certain multiunit structures for residential and/or commercial use containing four or
[[Page 21458]]
more units. These include structures where the units are reached through a common entrance or entrances from the street. Structures where apartments or commercial units are accessed from individual entrances, such as townhouses, will not be subject to this Standard.

Only new structures and existing structures undergoing substantial renovation, as defined below, would be required to install receptacles meeting the requirements of Standard 4C. In addition, any owners seeking new service or the resumption of mail service shall be required to install receptacles meeting Standard 4C (for example, a warehouse that converts to a residential or multiunit use that qualifies for centralized delivery). The new STD4C would be implemented 2 years from its publication. This period will be measured by the date that an application for a permit for the structure is submitted with the appropriate government officials. That is, if the permit documents are submitted less than 2 years after the publication of the new Standard in the Federal Register, the building owners will be encouraged, but not required, to install receptacles meeting the Standard 4C specifications. Instead, these buildings may install receptacles meeting the requirements of Standard 4B for up to 180 days after publication of the Final Standard in the Federal Register, or the securityenhanced Standard 4B+ (described below). If a permit application is submitted 2 or more years after publication of the Final Standard in the Federal Register, the receptacles in the building must meet the Standard 4C specifications.

The determination whether any building project is a ``substantial renovation'' requiring the installation of new STD4C receptacles is based upon the nature of the project. Projects involving structural alterations in the mailbox area that create the opportunity to accommodate wallmounted mail receptacles meeting the Standard 4C requirements may be considered substantial renovations. In contrast, routine, intermittent maintenance; painting; replacement, repair, or upgrades of carpets, floors or furniture; and replacement or repair of mail receptacles will not be considered ``substantial renovation'' when standing alone; a different conclusion may apply if such work is part of more substantial projects. For purposes of this determination, the term ``mailbox area'' shall be broadly construed and is not limited to the precise space in which mailboxes are located. Rather, it will include the aggregate area in which the mailboxes are housed, such as the lobby area of the building if that is where the boxes are located.

A building project determined to be a ``substantial renovation'' under this standard will not invariably require the installation of STD4C receptacles. Postmasters may grant exceptions in appropriate circumstances from all or portions of the Standard 4C requirements (e.g., a postmaster may grant an exception from the parcel locker requirement if the building management agrees to accept oversized mail and packages for tenants, while not excusing compliance with requirements for the new form factor in individual customer receptacles). Such circumstances include, but are not limited to, a finding that the changes required to install STD4C receptacles will cause the building to violate local building codes or other laws (e.g., by restricting access to or egress from the building), will create significant safety hazards (e.g., disturbance of asbestos), or will impose unreasonable financial hardship on the owner. Building owners seeking an exception from the need to install STD4C receptacles under these provisions should submit documentation substantiating the reason(s) for their request to the postmaster.

Building owners that replace receptacles more than 2 years after the publication of the Standard 4C, but that are not required to meet the requirements of that Standard (i.e., because it is not a new or substantially renovated building or because the owner has received an exception from the Postal Service), will be required to install replacement receptacles that instead meet the requirements of a modified version of Standard 4B (referred to as Standard 4B+). In general, this modified version will maintain the size requirements of Standard 4B; however, more stringent security requirements will be required for certain critical features of the boxes.

Receptacles that are not approved under the requirements of either Standard 4C or 4B+ may not be installed in buildings more than 180 days after the publication of Standard 4C, even though those receptacles were approved receptacles under Standard 4B. Receptacles meeting the requirements of Standard 4B+ may be installed in new buildings if the permit application has been submitted less than 2 years after publication of the Final Standard in the Federal Register.

Approval Process for Receptacles

In order to be eligible for Postal Service carrier mail delivery, receptacles must be approved by the Postal Service. In order to receive approval under STD4C, the manufacturer must submit the receptacle(s), along with the supporting materials listed in section 6 of the Standard, to the Postal Service at the following address: ATTN Delivery and Retail Systems, USPS Engineering, 8403 Lee Hwy, Merrifield VA 220828101.

In addition, manufacturers that are currently authorized to distribute delivery equipment under STD4B will be required to upgrade the receptacles and seek recertification of those receptacles under STD4B+. New manufacturers will not be permitted to submit STD4B+ receptacles. If this proposal is adopted, the Postal Service will provide notice to manufacturers that manufacture receptacles that were approved under Standard 4B concerning the need for reapproval under Standard 4B+, the STD4B+ specifications, and the timetable for obtaining recertification, which is shown below. Submissions should be sent to USPS Engineering at the above address.

The Postal service also proposes changing the Domestic Mail Manual (DMM) to ensure that manufacturers are aware of the specifications and procedures to obtain approval of their receptacles. Additional provisions would ensure that customers in structures in which delivery is to be provided through wallmounted receptacles are aware of the need to provide approved equipment as a condition for such delivery.

Although exempt from the notice and comment requirements of the Administrative Procedure Act [5 U.S.C. 553(b), (c)] regarding proposed rulemaking by 39 U.S.C. 410(a), the Postal Service invites comments on the following proposed revisions of the DMM incorporated by reference in the Code of Federal Regulations (CFR), see 39 CFR part 111, and Standard USPS4C.

3.1 General Design and ConstructionThe general configurations of the wallmounted, centralized mail receptacles shall conform to the requirements as described in this standard. The receptacles shall be designed and constructed so that they can be serviced according to the intended method, front or rear access. The receptacles shall be designed to allow wall mounting in accordance with the installation requirements as stipulated in this document and the applicable sections of the current Postal Operations Manual (POM) as referenced in section 2.2. The receptacle design shall preclude access from one compartment to another and it shall provide the required level of security for all receptacle contents and resistance to vandalism. The clearance between shelving sides and interior sides or rear walls shall prevent the passage of a 3\1/2\inch (height) by 5inch (length) by .007inch thick card from one compartment to another.

The design of all wallmounted, centralized mail receptacles may be of the types specified in 1.2. The design of all receptacles shall be such that the unit can be installed either indoors or outdoors. Outdoor installations shall be in compliance with conditions as described in this document and the applicable sections of the POM without damage or deterioration to the materials of the receptacle or to its contents. Each unit shall be made of the exact materials, construction, coating, finish, etc., as shown on the manufacturer's drawings, which are identified and certified by the Postal Service. The overall height, width, and depth of any receptacle shall be such that all the applicable mounting requirements shall be met.

All frontloading receptacles shall have fixed solid backs.

3.2 MaterialsLatitude shall be allowed in the materials used. The thickness, form, and mechanical and chemical properties of the material shall be adequate to meet the operational, structural, and performance requirements set forth in this standard. Materials must be compatible with each other; nontoxic and nonirritating to humans. Dissimilar metals shall be protected against galvanic corrosion. The material used in the fabrication of this equipment shall be new, suitable for the purpose used, free from all defects, and of the best commercial quality for this type of equipment.

3.3 Colors, Coatings and FinishesExterior colors and finishes of the receptacles, in general, shall be optional with the manufacturer. Any finish or coating selected should meet all the requirements of this document.

3.4 Mounting and HardwareThe hardware for attaching the receptacle to the wall shall be provided and packaged with the unit. All mounting hardware shall meet the corrosion resistance requirements of this document. Mounting hardware shall not protrude from any part of the unit to create a hazardous catch or bump point for customers or carriers. The mounting hardware shall be accessible for replacement in the event of damage to the unit and shall be hidden from public view while in service. The mounting technique and hardware selected shall allow the receptacle, when wallmounted in accordance with the manufacturer's instructions, to meet the pull requirements of section 4.11.9.

3.5 Customer and Parcel Compartment DoorsAll compartment doors shall meet the common requirements listed in this section. In addition, each type of compartment doors shall meet any unique door requirements as described in 3.5.1 through 3.5.4 below.

All compartments of frontloading receptacles shall have their own door and shall be hinged on the right. The door hinges shall be concealed or designed to prevent tampering. The doors shall be designed to open, close, and lock without binding or excessive play. All doors shall open a minimum of 90 degrees. The clearance between
[[Page 21461]]
door and door opening shall be evenly spaced, consistent in size, and minimized to preclude prying with such simple tools as knives, screwdrivers, thin metal strips, etc.

Optional compartment heights, requiring doors or blanking plates larger than the minimum, shall be allowable, except as stated in section 3.5.3. However, no offered compartment height shall preclude any of the critical installation requirements, or any other requirement, from being met. In addition, no compartment size shall be offered as ``approved'' that is larger than any Postal Servicetested and approved size for that particular manufacturer.

3.5.1 Customer Compartment DoorsOnce opened, a customer door shall remain in the opened position until closed and locked. Each door shall permit the mounting of a lock as required by 3.10.1.

3.5.2 Parcel Compartment DoorsThe doors shall be spring loaded to return the doors to the fully closed position. The spring shall be of sufficient strength to close the door from any opened position. The strength of the spring shall not be excessive as to create the potential for injury or cause the doors to ``slam'' shut. Each door shall permit the mounting of locks as required by 3.10.2.

3.5.3 Carrier Access (Arrow Lock) Door (Front Loader Designs)The carrier access door shall have accommodations for mounting either Arrow lock shown in figure 13 in such a manner that the modified Arrow lock cylinder is flush with the front of the compartment door and the standard Arrow lock is slightly recessed. This door shall be designed to accommodate the mounting of the Arrow lock and the securing of a minimumsized (3 inches high by 12 inches wide by 15 inches deep) compartment, which typically shall be used for retrieval of collection mail. For security reasons, under no circumstances shall this door be offered in any larger sizes. Once opened, the carrier access door shall remain in the opened position until closed and locked. This door shall not be numbered or lettered.

3.5.4 Collection Mail Compartment Blanking Plate (Rear Loader Designs)Rear loader receptacles shall have a blanking plate, sized to cover a minimum 3 inches high by 12 inches wide compartment, directly beneath the collection mail slot. This plate ensures a minimally acceptable compartment volume for the customer outgoing mail on rear loaders.

3.6 Master Loading Door(s)

3.6.1 Front Loader DesignsThese units shall be equipped with a master loading door(s) on the same side as the individual compartment and parcel doors. The master loading door(s) shall allow access to all the unit's customer compartments and parcel compartments for the deposit of letter mail and parcels and the collection of customer outgoing mail. The master loading doors shall be designed not to interfere with the loading of customer and parcel compartments. These doors shall be designed so the withdrawal of mail through the individual customer doors allows the mail to slide smoothly over any parts of the master, customer, or parcel doors. The master loading door(s) shall be easy to open and close. For any double master loading door design, the doors shall be hinged on opposite sides and latched at the center of the unit. The door hinges shall be continuous or concealed and designed to prevent tampering. The doors shall lock in the open position by an automatic selflocking device until the delivery employee completes loading. The doors shall be held open at an angle of 90 degrees (+5,0). The delivery employee shall be able to easily release the hold open device to close the door when loading has been completed. The door holdopen device shall withstand an inward or outward pull of 50 (+5, 0) pounds when applied to the master door edge farthest from the master door hinge and in a direction perpendicular to the door. (Note: For any nonparcel compartment design, disregard parcel compartment references.)

The master loading door for any single door receptacle design and the right master loading door for any double master door design shall, as a minimum, have provisions and accommodations for a threepoint (top, middle, bottom) latching mechanism, exclusive of the hinges, in conjunction with either a standard or modified Arrow lock to secure the door. Unless used solely as an actuator for locking pin(s), the Arrow lock shall lock the master loading door latch mechanism to ensure that the master loading doors are securely latched and that the latch mechanism cannot be moved. A limited loading shall be permitted on the end of the Arrow lock bolt only when the Arrow lock is used as an actuator to engage locking pins. In this case, the locking pin(s) shall secure the Arrow lock door to the master loading door frame. Only Arrow locks dimensioned in figure 13 shall be acceptable. The latching mechanism shall be rigid in design to avoid distortion. Locknuts shall be included for installing the Arrow lock. The master loading door(s) shall be easy to open, close, and lock. The carrier access shall not have pinch points or sharp edges. Clearance between the door and door opening shall be evenly spaced and consistent in size. The master loading doors shall be easily unlatched and opened using one hand. The latch mechanism may be mounted either on the unit frame or the master loading door. Clearance below the latch handle in either case shall be a minimum of 1.25 inches. When the carrier activates a master loading door latch mechanism mounted on the unit frame, the outer edge of the master loading door shall be automatically opened a minimum of 1 inch outside the door frame, enabling the carrier to easily grasp the door. When the latch mechanism is mounted on the unit frame, the handle must provide between 1.25 and 1.50 inches of grip length and a minimum of 1 square inch of surface area. When the carrier activates a master loading door latch mounted on the door, the latch handle may be used to pull the door open. When the latch mechanism is mounted on the door, the handle must provide a minimum of 1.75 inches of grip length. In any double master door design, when the master loading door with the Arrow lock traps, or locks the left master loading door, a pushout device shall not be required if the carrier can easily grasp and open the left door.

3.6.2 Rear Loader DesignsThe master loading door for any rear loading units shall be in the form of a rear cover or door, which can be opened or removed and closed or replaced by the mail carrier, which will permit delivery of mail to each compartment. The cover or door shall prevent the mail from falling out between the cover or door and shelves, and be strong enough to prevent theft of the contents of adjoining receptacles by manually forcing the rear door or cover from the front of the receptacle through a compartment. The cover or door shall be capable of being latched or secured; locking is not required.

3.7 Customer and Parcel Compartment SizesCustomer and parcel compartment size requirements shall be as specified below.

For any double master door designs, the numbers or letters shall start from the upper left corner compartment. In addition, they shall be \3/4\ to 1 inch high, sequential, black, and recessed. They may be engraved or stamped. Brushed aluminum decals with black numbering may be used, provided the decals are recessed in the door or a raised rib is provided around the decal to enhance the decal's location and limit removal. Decals shall be secured using a permanent type of adhesive. Numbers shall be made with one decal and not a combination of two single letter or number decals. In the horizontal direction, the centerline of the numbers shall be to the right of the customer lock (top lock) centerline. In the vertical direction, the customer lock and the numbers shall be the same centerline.

3.9.2 Parcel Compartment IdentificationParcel compartment doors shall be provided with \3/4\ to 1 inch high, sequential, black, recessed numbers. Numbers may be engraved or stamped. Brushed aluminum decals with black numbering may be used, provided they are recessed in the door or a raised rib is provided around the decal to enhance decal location and limit removal. Decals shall be secured using a permanent type of adhesive. Numbers shall be made with one decal and not a combination of two single letter or number decals. Raised lettering shall not be acceptable. Parcel compartment doors shall be numbered (typically, 1P, 2P, etc). In the horizontal direction, the centerline of the letters shall be to the right of the customer lock (top lock) centerline. In the vertical direction, the customer lock and the numbers shall be the same centerline.

3.9.3 Customer IdentificationA minimum \1/2\ inch wide surface shall be located below the front of each delivery compartment shelf. The surface shall be concealed by the master door(s) and shall be visible only by the carrier once the master door(s) is opened. The surface provided shall be smooth and will allow for the optional attachment of selfadhesive labels. Alternatively, each compartment may be equipped with either a clasp or holder to accommodate a name card, or supplied with a designated flat surface for a permanenttype pressuresensitive label for identifying the customer using the compartment. The holder or clasp shall be located on the frame above each compartment or inside of the compartment where the customer's name will be easily visible to the carrier when the box is opened for loading. The holder shall be of sufficient size to hold a name card of .75 inch by 2.50 inches or as large as space permits.

3.10 LocksLocks and cams shall be provided as specified below.

3.10.1 Customer Compartment LocksEach customer compartment door shall use a PSIN O910 lock, as specified in USPSL1172, or equivalent. The hole pattern for the lock is shown in figure 14. The hole shall be able to withstand 100 foot pounds of rotational torque, preventing the lock from being turned in the door allowing unauthorized entry into the compartment. The locks shall be oriented so that the locking cam rotates 90 degrees from the locked to the unlocked position. The key shall be removable only in the locked position. Individual customer locks shall be located in the compartment doors on the left side. Each lock shall be provided with three keys as specified in section 3.11.1. Key numbers shall not be placed on any exterior exposed surface. Cams shall be designed by the manufacturer to allow a secure grip of the lock to the compartment side wall.

All customer compartment doors shall be locked for shipment.

3.10.2 Parcel Compartment LocksEach parcel compartment door shall be configured to accept a combination 910/Arrow lock arrangement. The 910 lock shall serve as the customer access lock. Any parcel compartment provided as an integral part of a receptacle design shall have a 910 lock that is keyed differently than any customer compartment lock in the receptacle. The lock may itself provide the locking cam to secure the parcel door or it may be used as an
[[Page 21463]]
actuator in such a way as its cam moves locking pins into place to secure the parcel door. The locking pins would withstand the pry attack loads. The Arrow lock ``captures'' the 910 lock after its key has been inserted and the lock turned to allow the customer to remove their parcel. The Arrow lock and the 910 lock shall be located in a partitioned compartment and, for ease of maintenance reasons, shall not share the same compartment cover. The 910 lock cover shall be secured with standard hardware while the Arrow lock compartment cover shall be secured with tamper resistant screws. All parcel compartment doors shall be locked for shipment.

3.10.3 Master Loading Door Lock (FrontLoading Designs)Front loader receptacles shall be secured with an Arrow lock, in accordance with figure 13, to lock the master loading door(s) as defined in section 3.6.1. These units shall be configured so that the Arrow lock is always located directly beneath the collection mail slot. The mail slot and the Arrow lock door (carrier access door) shall share the same compartment but be separate items for security reasons. The Arrow lock shall be furnished and installed by the local postmaster or his representative. In addition, the Postal Service will provide dummy Arrow locks for test purposes upon request.

3.11 Keys and Key IdentificationAll compartment keys for locks in accordance with USPSL1172 or equivalent shall be identified and perform in the following manner to allow for efficient control, security, and operation. No two compartments in the same receptacle shall be keyed alike. In addition, the full complement of required key codes shall be utilized in sequential order prior to repeating any individual key code within a production lot of receptacles. All keys shall have any burrs removed and shall move freely in and out of the lock. When the lock is installed and the key is inserted, the locks must be positioned so that the key is free to turn without binding or contacting/scraping any adjoining surface.

3.11.1 Compartment KeysThree keys shall be provided for each customer compartment and shall be delivered on a single key ring. All keys shall be temporarily identified for their respective compartment, bagged, and securely taped inside the collection compartment for shipping.

3.11.2 Parcel Keys and TagsHeavyduty, rigid, clear plastic tags with card inserts containing instructions to the Postal Service customer on the use of the key, shall be furnished with each key for an individual parcel receptacle. The plastic tags shall be 1\1/2\ \1/16\ inches wide by 3 \1/16\ inches long by \3/16\ (+\1/16\, 0) inches thick, and shall have an opening at one end for a key ring. All holes or openings shall be reinforced. The tags shall also have a swivel device for key ring mounting. Heavyduty rings for attaching the holder to the individual key shall be provided for parcel receptacle keys. The key shall not be easy to remove from the key ring. Each insert card shall be identified with a serial number that is the same as the mail receptacle unit's serial number. The cards shall be numbered (e.g., 1P, 2P, etc) to correspond with their respective parcel receptacles. Card insert lettering shall be legible and of sufficient size and contrast to be easily read. All keys shall move freely in and out of the lock. Three keys shall be provided for each receptacle lock, tagged with the clear plastic holder for their respective receptacle, and placed in the same bag with compartment keys.

The card insert shall be as follows:

Clear Plastic Holder YOU HAVE MAIL IN RECEPTACLE * with card insert (side UNLOCK TOP LOCK AND REMOVE MAIL. A & B) KEY REMAINS IN LOCK.
*NOTE: The manufacturer shall provide the numbers and names as specified above.

3.12 MarkingFor frontloading designs, there must be two inscriptions centered on the carrier access door: ``U.S. MAIL'' in a minimum of .50 inch high letters and ``APPROVED BY THE POSTMASTER GENERAL'' in a minimum of .18 inch high letters. For rearloading designs, these inscriptions must be centered on the blank panel of the outgoing mail compartment. These inscriptions shall be positioned in a vertical stack with ``U.S. Mail'' appearing above ``APPROVED BY THE POSTMASTER GENERAL.'' Markings must be permanent and may be accomplished by applying a decal, embossing on sheet metal, applying raised lettering on plastic, or using other methods that are suitable. In addition, a legible and permanently marked decal with ``USPSSTD 4C,'' the manufacturer's name, address, date of manufacture (month and year), unit serial number, and model number or nomenclature must be affixed to the receptacle in a location that is readily visible to carriers.

3.13 Assembly and Installation InstructionsA complete set of instructions including illustrations for assembling and installing the receptacle shall be prepared and provided with each receptacle.

4. TESTING REQUIREMENTS

4.1 Testing RequirementsUnits will be subjected to all applicable testing described herein. A unit that fails to pass any test will be rejected.
[[Page 21464]]
Testing will be conducted in sequence as listed herein and in table III.

4.2 Capacity

4.2.1 Customer CompartmentsCustomer compartments must meet minimum capacity requirements tested by insertion and removal of a standard test gauge which measures 215/16 inches high by 1115/16 inches wide by 1415/16 inches deep. The test gauge will be inserted with its 215/16inch dimension aligned in the vertical axis (perpendicular to the compartment floor). The gauge must be capable of easy insertion and removal, and while inserted, allow for the door(s) to be completely closed without interference.

4.2.2 Collection Mail CompartmentThe collection mail compartment must meet minimum capacity requirements tested by insertion through the mail deposit slot of 48 standard letters (4.00 inches high by 9.50 inches long by .12 inch thick) and 4 Express Mail or Priority Mail envelopes (9.50 inches high by 12.50 inches long by .50 inch thick). Letter and envelope thicknesses shall be achieved by inserting 8.5 inch by 11 inch paper.

4.2.3 Parcel CompartmentParcel compartments must meet minimum capacity requirements tested by insertion and removal of a standard test gauge which measures 1415/16 inches high by 1115/16 inches wide by 1415/16 inches deep. The test gauge will be inserted with a 1415/ 16 inch dimension aligned on the vertical axis (perpendicular to the compartment floor). The gauge must be capable of easy insertion and removal; and while inserted, allow for the door(s) to be completely closed without interference.

4.3 Operational RequirementsThe carrier access (Arrow lock) door, customer doors, parcel doors, master loading door(s), and hold open device(s) must be capable of operating 10,000 normal operating cycles (1 cycle = open/close) at room temperature, continuously and correctly, without any failures such as breakage of parts. The cycle rate for carrier access (Arrow lock), customer and parcel doors shall not exceed 3 seconds per cycle. The cycle rate for the master loading door(s) and hold open device(s) shall not exceed 10 seconds per cycle. Testing may be performed either manually or by means of an automated, mechanically driven test fixture that replicates a manual operation.

4.4 WaterTightnessA rain test in accordance with UL 771, section 47.7 shall be performed to determine a receptacle's ability to protect mail from water. Prior to the test, the unit shall be prepared by shielding the body of the receptacle so that only the master door, customer doors, and front frame elements shall be directly exposed to rain during the test. The rain test shall be operated for a period of 15 minutes on the customer compartment door (front) side of the mail receptacle. At the conclusion of the test, the outside of the unit is wiped dry and all doors are opened. The inside of the compartments must contain no water other than that produced by high moisture condensation.

4.5 Salt Fog ResistanceA salt fog test shall be conducted in accordance with method A5 of ASTM G85, Standard Practice for Modified Salt Spray (Fog) Testing. The salt test shall be operated for 25 continuous cycles with each cycle consisting of 1hour fog and 1hour dryoff. The unit shall be tested in a finished condition, including all protective coating, paint, and mounting hardware and shall be thoroughly washed when submitted to remove all oil, grease, and other nonpermanent coatings. No part of the receptacle may show finish corrosion, blistering, or peeling, or other destructive reaction upon conclusion of test. Corrosion is defined as any form of property change such as rust, oxidation, color changes, perforation, accelerated erosion, or disintegration. The buildup of salt deposits upon the surface shall not be cause for rejection. However, any corrosion, paint blistering, or paint peeling is cause for rejection. It is also valid for units made of plastic that employ metal hardware.

4.6 Abrasion ResistanceThe unit's coating/finish shall be tested for resistance to abrasion in accordance with method A of ASTM D968. The rate of sand flow shall be 2 liters of sand in 22 3 seconds. The receptacle will have failed the sand abrasion test if less than 15 liters of sand penetrates its coating or if less than 75 liters of sand penetrates its plating. This test is applicable to metal receptacle designs only.

4.7 Temperature Stress TestThe unit under test shall be placed in a cold chamber at 40[deg] Fahrenheit (F) for 24 hours. The chamber shall first be stabilized at the test temperature. After remaining in the 40[deg]F environment for the 24hour period, the unit shall be quickly removed from the cold chamber into room ambient and tested for normal operation. The removal from the chamber and the testing for normal operation shall be accomplished in less than 3 minutes. The room ambient shall be between 65[deg] and 75[deg] F. Normal operation is defined as operation required and defined by this document. The unit under test shall undergo a similar temperature test, as described above, at a temperature of 140[deg] F.

4.8 Structural Rigidity RequirementsPull loads of the specified magnitudes (see table II) shall be slowly applied at any point of the specific item of the unit under test. These forces shall be held for a time not to exceed one minute and then released. Supplemental bracing may be used to isolate the loading on the specific item to be tested. After the release of the load, the permanent deformation caused by the forces shall be measured. If the deformation exceeds the limit specified in table II, the unit under test has failed to meet the structural rigidity requirement.
