About this file
This document is an Excel attachment (J1) detailing technical requirements for Braille Mailing Containers for the Library of Congress. The container specifications include precise dimensional requirements (internal dimensions max 3 3/4" H x 11 1/2" W x 13" L, external dimensions max 4 3/8" H x 12 1/4" W x 14" L) with specific performance standards for material durability, environmental resistance, and structural integrity.
Key technical requirements cover material composition, protective capabilities, markings, handle design, and closure mechanisms. The container must withstand temperature ranges from -50°F to 140°F, protect Braille volumes from physical damage, feature an IP51 ingress protection rating, include specific government property markings, have a functional handle, and accommodate a 3" x 5" address card. The container is part of Solicitation 2025-NLS-0098, a public and open competition for the Library of Congress to procure Braille mailing containers under FAR Part 13.5 guidelines.

| 2.1 | Materials which may cause bodily harm by contact, inhalation, or ingestions shall not be used in construction of the container | |||
| 2.2 | Container shall not deteriorate or show evidence of decrease in strength and functionality when exposed to conditions of temperature 115 degrees F + 10 degrees and 90% relative humidity for 24 hours | |||
| 2.3 | Container shall not deteriorate or show evidence of decrease in strength and functionality when exposed to conditions of temperature -50 degrees F - 10 degrees and 20% relative humidity for 24 hours | |||
| 2.4 | Container shall not deteriorate or show evidence of decrease in strength and functionality when exposed to conditions of temperature 140 degrees F + 10 degrees and 20% relative humidity for 24 hours | |||
| 2.5 | Container shall be dark in color so as to avoid showing wear. | |||
| 2.6 | The material used in construction of the container shall resist scuffing and fading. | |||
| 2.7 | In dyed materials, all dyes must remain fast after exposure to the temperature and humidity extremes described in 2.2, 2.3, 2.4, or after exposure to water. | |||
| 3 | Braille Volume Protection | |||
| 3.1 | Container shall protect the braille volume from physical damage | |||
| 3.2 | Container shall have an ingress protection rating of IP51 according to IEC standard 60529 | 5 = Dust protected | Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment. | |
| 3.3 | There shall be no separation of container materials or gaps in the construction after subjecting the container fully configured for mailing to the drop test defined below. | 1 | Dripping water | Dripping water (vertically falling drops) shall have no harmful effect on the specimen when mounted in an upright position onto a turntable and rotated at 1 RPM. |
| 1) place a container fully configured for mailing, but empty, face down on the floor | Test duration: 10 minutes | |||
| 2) place a four pound object approximating the dimensions of a braille volume into a second container | Water equivalent to 1 mm rainfall per minute | |||
| 3) raise the second container to a height of 36" (measured from the lowest point of the second container) | ||||
| 4) drop the second container so as to strike the center of the rear face of the first container (test unit) with one edge | ||||
| 5) repeat the test for a total of 3 drops | ||||
