10、f specimens has completed the 24-hour phase, they shall be rotated and tested to the next higher phase (group I goes to group II, group II goes to group III, group III goes to group I). This is continued until each group of specimens has been through each group of tests for a total of a 72-hour cycl
11、e. Each connector shall be unmated and remated during the transfer from group to group. Provisions shall be made to remove power from the connectors while they are unmated and remated. 4.3 Test condition C, aircraft The test specimens shall be placed in a sealed chamber of such size that can readily
12、 be attached to a vibrator table. The wiring of the connectors, see 3.2.2, between the load and the connector, and between the source and the connector shall be such as to maintain the sealed condition of the chamber. The chamber conditions shall provide the following cycle: 4.3.1 Reduce chamber pre
13、ssure to 4.39 x lo3 Pa f 0.68 x lo3 Pa (1.3 inches of mercury f 0.2 inch of mercury). Maintain for 8 hours. Copyright Electronic Components, Assemblies maintain for 10 hours. 4.4.2 Within 1 hour change chamber conditions to 49 “C f 3 “C (120 “F f 5 OF), 80% f 5% relative humidity; maintain for the r
14、emainder of a 1 O 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
15、completion of 4.4.2, place specimens in a chamber -55 “C f 3 “C (-67 “F * 5 OF), 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 s
16、hall 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 c
17、ycles: 4.5.1 Group1 4.5.1.1 Initial chamber conditions 21 “C f 3 “C (70 “F f 5 OF), 50% 4 5% relative humidity; maintain for 10 hours. 4.5.1.2 Within 1 hour change chamber conditions to 49 “C f 3 “C (120 “F f 5 OF), 80% f 5% relative humidity; maintain for the remainder of a 1 O hour period. 4.5.1.3
18、 With 1/2 hour place specimens in a chamber at -55 “C f 3 “C (-67F f 5 OF), maintain for the remainder of a 4 hour period. Copyright Electronic Components, Assemblies see table 2; maintain for 23 hours. 4.5.2.2 Remove specimens fi-om pressure vessel and allow 1 hour for air drying. 4.5.3 After each
19、group has completed one cycle as described above, the group II specimens are unmated, remated and switched so group I specimens go through group II test and group I i specimens go through group I tests to provide a 48 hour cycle. The transfer of specimens shall be accomplished within the first hour
20、of the first phase of each group. Provisions shall be provided to remove power from connectors while they are unmated and remated. 5 Details to be specified The following details shall be specified in the referencing document: 5.1 Number of specimens to be tested 5.2 Conductor size, if not matched t
