4.3.2 Inject air, at atmospheric pressure, into the top of the chamber. The injected air shall be 88 °C ± 3 °C (190 °F ± 5 °F) and shall bubble through water at 88 °C ± 3 °C (190 °F ± 5 °F). Maintain for 4 hours at atmospheric pressure.
4.3.3 During the last hour of 4.3.2 vibrate chamber and connector package through one complete cycle as specified. This provides a 12 hour cycle.
4.4 Test condition D, marine The test specimens, initially at room temperature, shall be placed in suitable chambers and subjected to the following cycle:
4.4.1 Initial chamber contains 21 °C ± 3 °C (70 °F ± 5 °F), 50% ± 5% relative humidity; maintain for 10 hours.
4.4.2 Within 1 hour change chamber conditions to 49 °C ± 3 °C (120 °F ± 5 °F), 80% ± 5% relative humidity; maintain for the remainder of a 10 hour period.
4.4.3 Immediately upon completion of 4.4.2 remove specimens and submerge immediately in synthetic ocean water, (see ASTM D 1141-52) at room temperature. (Specimens shall be removed as soon as entire connector has passed beneath the surface).
4.4.4 Within 1/2 hour from completion of 4.4.2, place specimens in a chamber -55 °C ± 3 °C (-67 °F ± 5 °F), maintain for 2 hours.
4.4.5 The test specimens shall carry the load specified in 3.2.5 through 4.4.1, 4.4.2 and 4.4.4 of this cycle. At the end of the cycle, connectors shall be allowed to warm to room temperature and shall be unmated and remated. This provides a 23 hour cycle. Provisions shall be made to remove power from connectors while they are unmated and remated. 4.5 Test condition E, underwater The test specimens initially at room temperature shall be divided into two groups and subjected to the following cycles:
4.5.1 Group I 4.5.1.1 Initial chamber conditions 21 °C ± 3 °C (70 °F ± 5 °F), 50% ± 5% relative humidity; maintain for 10 hours.
4.5.1.2 Within 1 hour change chamber conditions to 49 °C ± 3 °C (120 °F ± 5 °F), 80% ± 5% relative humidity; maintain for the remainder of a 10 hour period.
4.5.1.3 With 1/2 hour place specimens in a chamber at -55 °C ± 3 °C (-67°F ± 5 °F), maintain for the remainder of a 4 hour period.
