14、 C 3 C (70 F 5 F). 2.1.2 Pressure vessels used to conduct the hydrostatic pressure tests shall be designed in accordance with the ASME Pressure Vessel Code. 2.1.3 Vibration test equipment shall be specified. 3 Test specimen 3.1 Description A test specimen shall consist of a mateable assembly. 3.2 Pr
15、eparation 3.2.1 The test specimens shall be visually examined for chips, cracks, tears, loose or missing parts, proper lubrication, proper assembly and mateability. Any specimen that shows degradation, wear or any other physical defect shall be replaced before testing. EIA/ECA-364-22B Page 2 3.2.2 T
16、he test specimens shall be wired and assembled according to the manufacturers or military recommendations. Maintenance aging preconditioning shall be conducted in accordance with prescribed procedures on all connectors having removable contacts and shall consist of one removal and insertion of all o
17、f the contacts in each plug and receptacle. 3.2.3 Unless otherwise specified, the test specimens shall be wired with conductor sizes matching the contact size in the connector. The wire type and configuration shall be that specified, or that recommended by the connector manufacturer when no military
18、 specification exists. 3.2.4 Alternate contacts of the connector shall be wired in a series circuit, see figure 1, between a source and a load such that adjacent contacts are at opposite potential wherever possible. In the event that the connectors have more than one size contact, each contact size
19、shall be wired as separate connectors. Figure 1 - Wiring diagram typical 3.2.5 The mated, wired connectors shall be connected between a source and a load such that each circuit will be continuously carrying the maximum operating voltage. The operating voltage and rated current shall be that specifie
20、d or that recommended by the manufacturer when no military specification exists. 3.2.6 The test cycles described herein represent a particular area of connector application and are complete within themselves. Testing of one connector specimen shall be limited to one application category although thi
21、s cycle may be run as many times as required to provide the necessary number unit hours. 3.2.7 The criteria for failure of the test specimen shall be determined by the following: The test specimens shall operate the load specified in 3.2.5 throughout the entire cycle. The total life of the connector
22、 shall then be the total number of unit hours the load is operated. EIA/ECA-364-22B Page 3 4 Test procedure 4.1 Test condition A, general duty land The test specimens initially at room temperature shall be divided into two equal groups, placed in suitable chambers, and subjected to the following cyc
23、les: 4.1.1 Group I 4.1.1.1 Initial chamber conditions to be 21 C 3 C (70 F 5 F), 50% 5% relative humidity; maintain for 11 hours. 4.1.1.2 Raise chamber condition to 39 C 3 C (100 F 5 F), 80% 5% relative humidity to be accomplished over 1 hour period; maintain conditions for 11 hours. 4.1.1.3 Return
24、to initial specimen condition (room temperature), with drop accomplished over a 1 hour period. 4.1.2 Group II, see table 1 4.1.2.1 Initial chamber conditions to the specified limit of T1 3 C ( 5 F) with uncontrolled humidity; maintain for 10 hours. 4.1.2.2 Drop chamber conditions to the same applica
25、ble limit of T2 3 C ( 5 F), with uncontrolled humidity; drop to be accomplished over a 2-hour period; maintain condition for 10 hours. 4.1.2.3 Return to initial specimen condition (room temperature with rise accomplished over a 2 hour period. 4.1.3 After each group completed one cycle as described a
26、bove, the specimens are unmated, remated, and switched so that group II goes through the group I cycle and group I goes through group II cycle. This provides a 48-hour cycle for each group. The transfer of specimens shall be accomplished within the first hour of the first phase of each cycle. Provis
27、ions shall be made to remove power from the connectors while they are unmated and remated.
