3.5.3.5 Shock (4.6.4.3). The assembly shall be designed to withstand the shock test specified in 4.6.4.3 without
damage, deterioration, or degradation of performance. The assembly shall satisfy accept-reject criteria of 4.6.4.3.3
following shock test.
3.5.3.6 Dust (fine sand) (see 4.6.4.4). The assembly shall be designed to withstand the dust (fine sand) test
specified in 4.6.4.4 without damage, deterioration, or degradation of performance. The assembly shall meet accept-
reject criteria of 4.6.4.4.3 following dust (fine sand) test.
3.5.3.7 Humidity (see 4.6.4.5). The assembly shall be designed to operate both intermittently and continuously at
relative humidities up to 100 percent at temperatures up to 50°C, including conditions where condensation takes
place in or on the equipment without damage, deterioration, or degradation of performance. The assembly shall
3.5.3.8 Salt-fog (see 4.6.4.6). The assembly shall be designed to withstand the salt-fog test specified in 4.6.4.6
without damage, deterioration, or degradation of performance and shall satisfy accept-reject criteria of 4.6.4.6.3.
3.5.3.9 Explosion-proof (see 4.6.4.7). The assembly shall be made explosion-proof and shall not cause ignition of
the explosive mixture when subjected to the explosive atmosphere test as specified in 4.6.4.7. and shall satisfy
accept-reject criteria of 4.7.4.7.3.
3.5.3.10 Flammability (see 4.6.4.8). Non-metallic components of the assembly shall not be damaged and shall be
self-extinguishing within 6 seconds when tested as specified in 4.6.4.8 and shall satisfy accept-reject criteria of
3.5.3.11 Heat aging and cold bend (see 4.6.4.9). There shall be no evidence of cracks, flaws, or loss of flexibility
in the principal component parts of the coaxial assembly when tested as specified in 4.6.4.9 and shall satisfy accept-
reject criteria of 4.6.4.9.3.
3.5.3.12 Flow (see 4.6.4.10). The inner conductor shall not be displaced from the center of the cable by more than
10 percent of the diameter of the dielectric when tested as specified in 4.6.4.10. The test weight shall be as specified
in the detail specification.
3.5.3.13 Abrasion resistance (see 4.6.4.11). The coaxial assembly, flexible or semi-flexible, shall be capable of
withstanding 500 oscillations without the abrasion resistance testing coming into contact with the outer conductor in
the case of a flexible assembly, or without the abrasion resistance testing penetrating the outer conductor in the case
of semi-flexible assembly. The test shall be performed as specified in 4.6.4.11 herein and the assembly shall satisfy
accept-reject criteria of 4.6.4.11.3.
3.5.3.14 Chemical resistance (see 4.6.4.12). The coaxial assembly shall be resistant to chemicals and shall
withstand the test specified in 4.6.4.12 without degradation to any component of the assembly and shall satisfy
accept-reject criteria of 4.6.4.12.3.
3.5.3.15 Leakage (contaminants) (see 4.6.4.13). The coaxial assembly shall be designed to withstand the tests
specified in 4.6.4.13.1 without damage, deterioration, or degradation of performance. The test assembly shall satisfy
accept-reject criteria of 4.6.4.10.3. Assemblies subjected to test procedures I, II and III shall satisfy accept-reject
3.6 Interchangeability. Interchangeability requirements must be in accordance with the following:
a. Design tolarances. Design tolerances should permit parts, subassemblies and assemblies to be used in
their parent assemblies without regard to the source of supply or manufacturer. Parts, subassemblies and
assemblies having the full range of dimensions and characteristics permitted by the specification governing the
part, subassembly,or assembly should be usable as replacement items without selection and without departure
from the specified performance guidelines of the parent items.
b. Parts and materials. When permission is granted to use nonstandard part or material because the existing
standard part or material is not avaiolable, the equipment should be so designed that the nonstandard part or
material and the standard part or material are interchangeable. When the specification for the part or material
