ANSI ECA-364-22B:2000 pdf download.Simulated Life Test Procedure for Electrical Connectors.
ANSI ECA-364-22B establishes test methods to determine the adequacy of a connector or socket to perform its operational function on land (general and heavy duty), aircraft, marine or underwater for the representative time period of application. This method shall not be used prior to low level measurement per EIA-364-23.

2.1 Test equipment
2.1.1 Separate chambers may be used to conduct the tests noted for extreme temperature conditions. Chambers shall recover within 2 minutes after specimen transfer. Room temperature shall be 21 °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 specitied.
3 Test specimen
3.1 Description
A test specimen shall consist of a mateable assembly.
3.2 Preparation
3.2.1 The test specimens shall be visually examined for chips. cracks, tears, loose or missing parts, proper lubrication, proper assembly and maleahility. Any specimen that shows degradation, wear or any other physical defect shall be replaced before testing.
3.2.2 The test specimens shall be wired and assembled according to the manufacturer’s 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 of 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 he that specified, or that recommended by the connector manufacturer when no military 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 shall be wired as separate connectors.
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 specified 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 he limited to one application category although this cycle may he 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 shall then be the total number of unit hours the load is operated.ANSI ECA-364-22B pdf download.
