FIGURE 2. Vibration testing setup.

4.9.27 Fluid immersion (see 3.11.27). At least one mated cable-connector assembly shall be tested in

accordance with EIA/TIA-455-12. Assemblies shall be immersed in each of the fluids listed in table VIII at

the temperature specified for 24 hours. Each assembly shall be completely dried after each immersion.

After testing, the assemblies shall be examined for fluid penetration into the shell body and connector

junction region. Instead of optical transmittance, insertion loss shall be measured after the test (see

TABLE VIII. Fluids and test temperature for immersion test.
