2.4 Order of precedence. The order of precedence delineated in the general specification, S-311-P-718 shall apply.

3.0 REQUIREMENTS (1.2)

3.1 Materials, designs and construction. Backshells and their associated integral parts shall be of the materials, design, construction, platings, and physical dimensions as specified herein. (Figures 1 through 20) (Reference: Finishes not specified, which are known to sublimate in a hard vacuum, such as cadmium, shall not be used.)

3.1.1 Material weiaht loss (vacuum). All backshell constituent parts used shall be such that in no case will outgassing limits of 3.1.4 be exceeded when tested in accordance with GSFC S-311-P-718.

3.1.2 Materials. Materials shall be suitable for the purpose intended and as specified (see 3.1), however, when a definite material is not specified,a material shall be used which will enable the backshells to meet the performance requirements of this specification. Acceptance or approval of any constituent material shall not be construed as a guarantee for acceptance of the finished product.

S-311-P-718/4 PAGE 4 REV: --

3.1.3 Backshell weight. The maximum weight of each backshell kit shall be in accordance with Figures 1, 11 and 16.

3.1.4 Vacuum effects (materials outgassing). The material outgassing limits of all materials used shall not exceed 1.0 percent in total weight loss and 0.1 percent in volatilecondensable material.

3.2 Identification marking. Each backshell housing (kit) shall be permanently and legibly marked per MIL-STD-130 with the backshell type designation and date-lot identification. constituent kit parts need not be marked with the GSFC identifier, e.g. S-311-P-718/4-1.

3.3 Performance.

3.3.1 EMI effectiveness. The EMI effectiveness provisions of GSFC S-311-P-718 apply.

4.0 QUALITY ASSURANCE PROVISIONS (1.2)

4.1 Final inspection. Each backshell kit (and constituent piece part) shall be:

a. 100% inspected per the workmanship provisions of the general specification, GSFC S-311-P-718

b. checked for critical dimensions (per applicable figure)
