The revised standard, which shall be designated U.S. Postal Service Standard 7B, Mailboxes, Curbside, adopts the recommendations of the USPS Curbside Mailbox Standard Revision Consensus Committee. The members of the Committee met as an advisory group and negotiated among themselves and with the Postal Service to reach a consensus on a new standard. 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 consensus process, the Postal Service agreed to use a recommendation by the Committee as the basis of the new standard. In addition, each private member of the Committee agreed that, if it agreed to a recommendation by the Committee, it would support that recommendation and the new standard to the extent that it reflects the recommendation. After the Consensus Committee held several meetings that were open to the public, the Committee approved and recommended the standard set forth below and agreed that the benefits of the standard outweighed its costs.
Changes incorporated in the proposed new standard include the following:Start Printed Page 9510
1. Eliminated the requirement that “Traditional” mailboxes must be built in conformance with USPS drawings (formerly designated T1, T2, & T3). All three USPS drawings were eliminated and replaced with a new figure, which gives manufacturers more design flexibility.
2. Removed all requirements to comply with military and federal specifications and standards.
3. Deleted flammability, solar exposure, and color intensity test requirements that were determined to be invalid or unnecessary.
4. Dropped requirement that manufacturers comply with the National Motor Freight Classification Rule 222.
5. Introduced a new “Locked” mailbox classification with two new figures. This design will provide customers with an option to purchase mailboxes that offer increased security for their mail.
6. Incorporated quality assurance provisions.
7. Added a figure depicting three new alternative flag designs.
8. Included new guidelines and a figure for acceptable door handle/knob designs.
9. Clarified application requirements and introduced independent laboratory testing.
Comment and Analysis
The Postal Service makes this revision after consideration of the single substantive comment submitted in response to the Notice of Proposed Rulemaking published in Vol. 65 Federal Register No. 212 on November 1, 2000. The commenter recommended that the proposed standard be modified to permit use of retrofit locking devices on mailboxes. The commenter argued that such devices would address mail theft concerns, provide a low cost alternative to purchasing a locking mailbox, and enable more efficient carrier delivery.
Although the commenter recommends that retrofit locking devices be permitted only if they do not otherwise violate any provision of the new standard, the Postal Service and the Consensus Committee have concluded that the recommended modification should not be made.
The Postal Service has evaluated numerous locking devices intended to be retrofitted on customers' curbside mailboxes. In every case, mailboxes equipped with those devices required significant additional carrier effort. In addition, all were susceptible to incorrect homeowner installation and/or incorrect operation by carriers. These pervasive problems would decrease the effectiveness of mail security afforded by these devices and increase the operational difficulty of servicing mailboxes equipped with those devices. For these reasons, the Postal Service has consistently determined that retrofit locking devices should not be permitted on curbside mailboxes, and all members of the Committee opposed adoption of the change recommended by the commenter.
In response to concerns about mail security, the Consensus Committee recommended new design requirements for locked mailboxes. The new locked mailboxes permitted under the revised standard will not present any of the inherent problems associated with retrofit locking devices, and will provide increased mail security to customers.
Re-approval of Manufacturers' Curbside Mailboxes
The re-approval process for manufacturers with mailbox designs that were approved before the final publication date of USPS STD 7B will be conducted as follows. The approval process for all other mailbox designs will be conducted in accordance with USPS STD 7B, part 5.
1. The USPS will notify currently approved manufacturers within five business days after final publication of USPS STD 7B in the Federal Register when to submit their mailboxes for re-approval. All mailboxes must be submitted to: ATTN: Test Evaluation & Quality, USPS Engineering, 8403 Lee Hwy, Merrifield VA 22082-8101.
2. Manufacturers will have 90 days after receipt of this notification to submit a sample of each of their previously approved mailboxes. In addition, manufacturers shall submit their quality assurance manual, and each mailbox must be accompanied with a compliance certificate, one set of drawings, product information, and instructions. Mailboxes will be tested on a first-come, first-served basis.
3. If a previously approved mailbox is not submitted within the 90-day period, it will automatically lose its approval status. A manufacturer may receive an extension of up to 45 days, provided reasonable justification is demonstrated to the USPS. Manufacturers seeking an extension must write to: ATTN: Delivery & Retail Systems, USPS Information Platform, 8403 Lee Hwy, Merrifield VA 22082-8101.
4. The USPS will have up to 90 days to respond to submissions, during which time manufacturers can continue to sell their mailboxes.
5. If a submitted mailbox does not pass the revised standard's requirements, the manufacturer may make modifications and re-submit their mailbox one additional time. The manufacturer will have 45 days after the date of USPS's notice of denial of the manufacturer's first application to submit a second sample. Should the second sample fail testing, the manufacturer has up to 180 days from notification of failure to cease selling it. The manufacturer is also to cease production immediately and use the 180 days to deplete existing inventory.
6. If a mailbox fails two testing attempts, manufacturers may still make modifications and re-submit in accordance with the new application requirements specified in the revised standard. However, the conditions identified in #5 above remain in effect.Start List of Subjects

3.2 General Design
Mailboxes must meet regulations and requirements as stipulated by USPS collection and delivery, operation and policy (see 2.2). This includes carrier door operation as stated in 3.4, flag operation as stated in 3.7, in-coming mail openings and the retrieval of out-going mail. The opening style, design and size are determined by the manufacturer, however, the carrier must be able to deposit the customer's mail. Out-going mail of all designs must be able to be pulled straight out of the mailbox without interference from protrusions, hardware, etc. Mailboxes must be capable of passing the applicable testing requirements in 3.15. Mailboxes must not be made of any transparent, toxic, or flammable material (see 3.3). The mailbox must protect mail from potential water damage that may result from wet weather conditions (see section 3.15.3). Any advertising on a mailbox or its support is prohibited. Additional specific requirements follow.
3.2.1 Traditional Designs (Limited & Full Service)
Figure 1 and meet capacity requirements specified in 3.15.1 will be classified as Traditional. Designs incorporating a carrier signal flag (see 3.7) will be classified as full service mailboxes. Designs with no flag will be classified as limited service (see 3.12). As specified in 3.5, a rear door is permitted to enable the customer to remove mail without standing in the street. The use of locks, locking devices or inserts is prohibited.
3.2.2 Contemporary Designs (Limited & Full Service)
Mailbox designs that do not conform to the dome-rectangular shape of Traditional designs but meet capacity requirements specified in 3.15.1 will be classified as Contemporary. In addition, Contemporary designs shall not exceed the maximum limitations on dimensions A, D, E, F and G in Figure 1. Designs incorporating a carrier signal flag (see 3.7) will be classified as full service mailboxes. Designs with no flag will be classified as limited service (see 3.12). Although the shape and design is less restrictive, Contemporary mailboxes must meet the same applicable functional requirements. Contemporary designs can also incorporate a rear door, as specified in 3.5, to enable the customer to remove mail without standing in the street. The use of locks, locking devices or inserts is prohibited.
3.2.3 Locked Designs
Mailbox designs that provide security for customer's in-coming mail will be classified as Locked mailboxes (see Figures 2 & 3). Although the shape and design is less restrictive, Locked mailboxes must meet the same applicable functional requirements. Designs having a slot for in-coming mail must be at least 1.75 inches high by 10 inches wide. If a slot has a protective flap it must operate inward to ensure mail can be inserted in a horizontal manner without requiring any additional effort of carriers (see Figure Start Printed Page 95123). The slot must be positioned on the front side of the mailbox facing the street. In addition, the slot must be clearly visible and directly accessible by mail carriers. Any designs, which allow for out-going mail, must meet all applicable requirements of this standard.
18.104.22.168 Full Service
Locked mailbox designs of this class allow for both in-coming and out-going mail as depicted in Figure 2. It is preferred that both in-coming and out-going mail compartments be located behind a single carrier service door as shown in Figure 2. Alternate positioning of the in-coming mail compartment such as beneath or side-by-side with the out-going compartment is permitted provided that no additional carrier service is introduced.
22.214.171.124 Limited Service
Locked mailbox designs of this class only allow for in-coming mail as shown in Figure 3.
3.2.4 Mailbox Accessories
Decorative art and devices can be attached to the exterior of approved mailbox designs provided they do not interfere with mail delivery or present a safety hazard. Devices can also be mounted in the interior of approved mailboxes provided they do not cause the intended mailbox to fail capacity test described in 3.15.1 and do not interfere with mail delivery or present a safety hazard. Any advertising on a mailbox or its support is prohibited. Unrestricted spring-loaded devices and designs are prohibited. Auxiliary flags or devices used to signal the customer that the mail has arrived must operate automatically without requiring additional carrier effort.
Ferrous or nonferrous metal, wood (restrictions apply), plastic, or other materials may be used, as long as their thickness, form, mechanical properties, and chemical properties adequately meet the operational, structural, and performance requirements set forth in this standard. Materials used must not be toxic, flammable or transparent.
3.3.1 Mailbox Floor
The entire bottom area of all mailboxes where mail would rest shall be fabricated to prevent mail from damage due to condensation or moisture. Except for the internal mail compartment of locked style mailboxes, all designs must not present a lip or protrusion that would prevent the mail from being inserted or pulled straight out of the mailbox. The surface of the floor cannot be made of wood material. The floor shall be ribbed as shown in Figures 1, 2, and 3 or dimpled, embossed, or otherwise fabricated provided the resulting surface area (touching mail) does not exceed .25 square inch (per dimple/impression) and is a minimum of .12 inch high on centers not exceeding 1 inch. A mat insert having a raised surface contour may be used for the internal mail compartment of locked style mailboxes only (see Figures 2 & 3).
3.3.2 Carrier Signal Flag
Cannot be made of wood. Plastic is the preferred material.
3.3.3 Door Handle
Cannot be made of wood. Plastic is the preferred material.
3.4 Carrier Service Door
There shall be only one carrier service door which must provide access for mail delivery and collection intended by the unit and meet USPS delivery operational requirements (see 2.2). The door must meet the applicable testing requirements specified in 3.15.2. The carrier service door must operate freely and solely by pulling outward and downward with a convenient handle or knob. The design of the door, including hinges and handles must provide protection against wind, rain, sleet, or snow (see 3.15.3). Door latches must hold the door closed but allow easy opening and closing requiring no more than 5 pounds of force. Action of the latch must be a positive mechanical one not relying solely on friction of the hinge parts. The door shall not be spring-loaded. Magnetic latches are acceptable provided adequate closure power is maintained during ambient conditions specified in 3.15.6 and applicable testing described in 3.15. It is preferred that by either tactile or by sound (i.e. “snap” or “click”) carriers are alerted that door is properly shut. The door, once opened, must remain in the open position until the carrier pushes it closed. The door must rotate a minimum of 100 degrees when opened and it is preferred that the maximum rotation be limited to 120 degrees or less. When in a fully opened and rest position, the opening angle of the door cannot measure more than 180 degrees. No protrusions other than the handle/knob, door catch, alternate flag design, decorative features or markings are permitted on the carrier service door. Protrusions of any kind that reduce the usable volume within the mailbox when closed are not acceptable. See section 3.2.3 for carrier service door requirements for Locked mailbox designs.
The handle or knob shall have adequate accessibility to permit quickly grasping and pulling it with one hand (with or without gloves) to open the door. The handle or knob shall be located within the top 1/3 of the door. Various acceptable handle/knob designs with required dimensions are depicted in Figure 5. Other designs may be acceptable provided they allow enough finger clearance and surface area for carriers to grasp.
3.5 Rear Doors
Mailboxes may have a rear door, provided that it does not interfere with the normal delivery and collection operation provided by the carrier or require the carrier to perform any unusual operations. The rear door must not be susceptible to being forced open as a result of large mail items such as newspapers and parcels being inserted through the carrier door. The rear door must meet the applicable testing requirements specified in 3.15.
Locked mailbox designs shall have an effective means to ensure that in-coming mail is only accessible by the customer. The use of locks on Contemporary and Traditional mailbox designs is prohibited. Manufacturers must include the following statement in their instructions to customers: IT IS IMPORTANT TO NOTE THAT IT IS NOT THE RESPONSIBILITY OF MAIL CARRIERS TO OPEN MAILBOXES THAT ARE LOCKED, ACCEPT KEYS FOR THIS PURPOSE, OR LOCK MAILBOXES AFTER DELIVERY OF THE MAIL.
3.7 Carrier Signal Flag
Traditional, Contemporary, and Locked mailbox designs classified as Full Service shall have a carrier signal flag. The flag design must be one of the approved concepts depicted in Figures 1, 2, and 4. As shown in each figure, the flag must be mounted on the right side when facing the mailbox from the front. The flag must not require a lift or more than 2 pounds of force to retract. Additionally, when actuated (signaling out-going mail) the flag must remain in position until retracted by the carrier. The color of the flag must be in accordance with requirements described in 3.10. The operating mechanism of the Start Printed Page 9513flag must not require lubrication and must continue to operate properly and positively (without binding or excessive free play) after being subjected to test described in 3.15. Optionally, the flag may incorporate a self-lowering feature that causes it to automatically retract when the carrier service door is opened provided no additional effort is required of the carrier. The self-lowering feature cannot present protrusions or attachments and must not interfere with delivery operations in any manner or present hazardous features as specified in 3.2.
The mailbox must bear two inscriptions on the carrier service 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. These inscriptions may be positioned beneath the in-coming mail slot for Limited Service Locked Mailboxes as shown in Figure 3. Markings must be permanent and may be accomplished by applying a decal, embossing on sheet metal, raised lettering on plastic, engraving on wood or other methods that are suitable for that particular unit. The manufacturer's name, address, date of manufacture (month and year), and model number or nomenclature must be legible and permanently marked or affixed on a panel (rear, backside of door, bottom or side interior near the carrier service door) of the mailbox that is readily accessible and not obscured.
3.8.1 Modified Mailbox Marking
Mailboxes that use previously approved units in their design must include marking stating the new manufacturer's name, address, date of manufacture and model nomenclature in a permanent fashion and location as described above. Additionally, The “U.S. MAIL” and “Approved By The Postmaster General” marking shall be reapplied if it is obscured or obliterated by the new design.
3.9 Coatings and Finishes
Choice of coatings and finishes is optional, provided all requirements of this standard are met. All coatings and finishes must be free from flaking, peeling, cracking, crazing, blushing, and powdery surfaces. Coatings and finishes must be compatible with the mailbox materials. Accept for small decorative accents, mirror-like coatings or finishes are prohibited. The coating or finish must meet the applicable testing requirements described in 3.15.5.
The color of the mailbox and flag must be in accordance with the following requirements. The mailbox may be any color. The carrier signal flag can be any color except any shade of green, brown, white, yellow or blue. The preferred flag color is fluorescent orange. Also, the flag color must present a clear contrast with predominant color of the mailbox.
The mailbox shall be provided with means for convenient and locked mounting that meets all applicable requirements of the POM. The manufacturer may offer various types of mounting accessories such as a bracket, post or stand. Although the USPS does not regulate the design of mounting accessories, it is pointed out that no part of them is permitted to project beyond the front of the mounted mailbox. Mounting accessories must not interfere with delivery operations as described in 3.2 or present hazardous features as described in 3.14. See section 6 for additional important information.
3.12 Instructions and Product Information
3.12.1 Assembly and Installation
A complete set of instructions for assembling and mounting the mailbox shall be furnished with each unit. The instructions must include the following conspicuous message: CUSTOMERS ARE REQUIRED TO CONTACT THE LOCAL POST OFFICE BEFORE INSTALLING THE MAILBOX TO ENSURE ITS CORRECT PLACEMENT AND HEIGHT AT THE STREET. GENERALLY, MAILBOXES ARE INSTALLED AT A HEIGHT OF 41-45 in. FROM THE ROAD SURFACE TO INSIDE FLOOR OF THE MAILBOX OR POINT OF MAIL ENTRY (LOCKED DESIGNS) AND ARE SET BACK 6-8 in. FROM FRONT FACE OF CURB OR ROAD EDGE TO THE MAILBOX DOOR.
3.12.2 Limited Service Mailboxes
The following conspicuous note shall be included with each mailbox: THIS IS A LIMITED SERVICE MAILBOX (WITHOUT FLAG) AND IT IS ONLY INTENDED FOR CUSTOMERS WHO DO NOT WANT POSTAL CARRIERS TO PICK-UP THEIR OUT-GOING MAIL. UNLESS POSTAL CARRIERS HAVE MAIL TO DELIVER THEY WILL NOT STOP AT LIMITED SERVICE MAILBOXES.
3.13 Newspaper Receptacles
A receptacle for the delivery of newspapers may be attached to the post of a curbside mailbox provided no part of the receptacle interferes with the delivery of mail, obstructs the view of the flag, or presents a hazard to the carrier or the carrier's vehicle. The receptacle must not extend beyond the front of the box when the door is closed. No advertising may be displayed on the outside of the receptacle, except the name of the publication.
The mailbox shall be properly assembled and utilize the best commercial practice workmanship standards in the fabrication of all components and assemblies. All movable parts shall fit and operate properly with no unintended catch or binding points. The unit must be free from harmful projections or other hazardous devices. The unit must not have any sharp edges, sharp corners, burrs or other features (on any surfaces) that may be hazardous to carriers/customers, or that may interfere with delivery operations as described in 3.2 (General Design).
3.15 Testing Requirements
Mailboxes will be subjected to all applicable testing described herein (specific requirements follow). A mailbox that fails to pass any test will be rejected. Testing will be conducted in sequence as listed herein and in Table III.
Traditional and Contemporary designs must meet minimum capacity requirements tested by insertion and removal of a standard test gauge which measures 18.50″ long x 5.00″ wide x 6.00″ high. The test gauge is inserted with its 6.00″ dimension aligned in the vertical axis (perpendicular to the mailbox 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. The capacity of Locked designs, which have slots, chutes or similar features, will be tested and approved based upon whether standard USPS mail sizes (see Table I) can be easily inserted through the mail slot or opening. Retrieval of this mail from the locked compartment shall be equally as easy.
|Description||Size (L × H × Thk)|
|Express & Priority Mail Envelopes||121/2″ x 91/2″ x 1/2″|
|Priority Mail Box||85/8″ x 53/8″ x 15/8″|
3.15.2 Operational Requirements
Carrier service doors, auxiliary doors, door catches/mechanisms, carrier signal flags and applicable accessory devices must be capable of operating 7,500 normal operating cycles (1 cycle = open/close) at room temperature, continuously and correctly, without any failures such as breakage of parts. Testing may be performed either manually or by means of an automated mechanically driven test fixture which essentially mimics a manual operation. This test is applicable to all mailbox designs.
A rain test in accordance with UL 771, section 47.7 shall be performed to determine a mailbox's ability to protect mail from water. The rain test shall be operated for a period of 15 minutes for each side. At the conclusion of the test, the outside of the unit is wiped dry and all doors are opened. The inside of the compartment must contain no water other than that produced by high moisture condensation. This test is applicable to all mailbox designs.
3.15.4 Salt Spray Resistance
A salt spray 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 1-hour fog and 1-hour dry-off. The mailbox 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 mailbox 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 build-up of salt deposits upon the surface shall not be cause for rejection. However, any corrosion, paint blistering, or paint peeling is cause for rejection. This test is primarily applicable to ferrous metal mailbox designs. It is also valid for mailbox designs made of plastic, wood, or other materials which use any metal hardware.
3.15.5 Abrasion Resistance
The Mailbox'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 mailbox 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 mailbox designs only.
3.15.6 Temperature Stress Test
The mailbox under test shall be placed in a cold chamber at− 65° Fahrenheit for 24 hours. The chamber shall first be stabilized at the test temperature. After remaining in the− 65° environment for the 24-hour 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° and 75° Fahrenheit. 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° Fahrenheit. This test is applicable to all mailbox designs.
3.15.7 Structural Rigidity Requirements
Forces of specified magnitude (see Table II) shall be slowly applied at specific points on the mailbox under test (see Figure 6). These forces shall be held for a minimum of one minute and then released. After their release, the deformation caused by the forces shall be measured. If the deformation exceeds the limit specified in Table II, the mailbox under test has failed to meet the structural rigidity requirement. The doors shall remain closed for test positions 1 through 6. The application of the forces at positions 1 and 2 shall be applied with the mailbox in its normal upright position, supported by a horizontal board. The application of the forces at positions 3, 4, and 5 shall be applied with the mailbox lying on its side (flag side down). The mailbox shall be supported, on the under side, by a flat board that is relieved in the immediate area of the flag mechanism. The application of force at position 6 (Traditional style flags only) shall be applied with the mailbox lying on its side (flag side up). The application of force at position 6 shall be repeated at the top of the flag with the mailbox in its normal upright position. If visible cracks, in the material, have developed as a result of the testing, the mailbox under test has failed to meet the structural rigidity requirement. At the conclusion of the Structural Rigidity testing, if the mailbox under test fails to operate normally, as defined by this document, the mailbox under test has failed to meet the structural Rigidity requirement. This test is applicable to all mailbox designs.
|Position||Deformation (inches)||Load (pounds)|
3.15.8 Impact Test
Refer to the Figure 6 for load positions. Precondition the mailbox for 4 hours at −20° Fahrenheit. The following testing shall be performed within 3 minutes of removing the mailbox from the temperature chamber. At both load positions 3 and 4, with the mailbox lying on its side (flag side down) with the door(s) closed, apply an impact load equivalent to a 10-pound weight dropped from a height of 3-feet above the mailbox surface onto a bolster plate having a surface not larger than 2 inches by 2 inches. The mailbox shall be supported, on the underside, by a flat board that is relieved in the immediate area of the flag mechanism. If any noticeable perforation, occurrence of sharp edges, or cracking of the material, either inside or outside the mailbox, develops as a result of the impact; or if the door becomes inoperable or fails to close normally, the mailbox under test has failed to meet the impact resistance requirement. This test is applicable to all mailbox designs.
4. APPLICATION REQUIREMENTS
4.1 Application Requirements
Requests for application materials, and all other correspondence and inquiries, shall be directed to the address in 1.3.2. The application process consists of:
4.1.1 Preliminary Review
Manufacturers must first satisfy requirements of a preliminary review prior to submitting any sample mailboxes or accessories. The preliminary review consists of a review of the manufacturer's conceptual design drawings. Computer generated drawings are preferred, but hand drawn sketches are acceptable provided they clearly depict the overall shape and interior size of the proposed mailbox design. Drawings must also include details on design of applicable features such as the carrier service door, latch, handle, flag, floor, and slot. In addition to drawings, proposed accessories shall show or Start Printed Page 9515describe intended function. If drawings show that the proposed mailbox design appears to comply with the requirements of this standard, manufacturers will be notified in writing and may then continue with the application requirements described in 4.1.2. Do NOT submit any sample mailboxes to the USPS prior to complying with the requirements of 4.1.2. Notification that a manufacturer's drawings satisfy the requirements of the preliminary review does NOT constitute USPS approval of a design, and shall NOT be relied upon as an assurance that a design will be approved.
Upon receiving written notification from the USPS that their design satisfies requirements of the preliminary review, manufacturers shall at their own expense submit one sample of their mailbox or accessory to an independent laboratory for testing along with a copy the preliminary review letter from the USPS. See Appendix A for a list of USPS approved independent test labs. Manufacturers with more than one unique model shall have each one tested independently. Models which are generally of the same size, shape, and material of previously approved designs but only have different decorative features (i.e. color scheme and surface contours) are not considered unique and do not require any testing. Manufacturers seeking approval of models that are not unique shall submit documentation for each model in accordance with section 126.96.36.199. This documentation will be reviewed and the proposed model will either be approved or disapproved (see section 5). The USPS may request manufacturer to submit one sample of the proposed model.
4.1.3 Final Review
