ANSI EIA-364-28D-1999 pdf download Vibration Test Procedure for Electrical Connectors and Sockets
3 Test specimen
3.1 A vibration test sample shall be a fully wired connector consisting of one of the following, as applicable;
3.1.1 A connector plug and its mating connector receptacle.
3.1.2 A printed circuit connector receptacle and its mating connector board(s).
3.1.3 An integral, functional connector assembly.
3.2 Each test sample shall be prepared with wire and other materials or processes, simulating application assembly of the sample. If normal connector mating is dependent upon forces extemal to the connector, then such forces and mounting arrangement shall be as closely duplicated as possible (example: printed circuit connectors). If mating is achieved with normal locking means, then only normal locking means shall be used.
3.3 Method of mounting
3.3.1 Test conditions I, I, and IV (sinusoidal evaluation conditions) The specimen shall be atached to a fixture capable of transmiting the vibration conditions specified. The test fixture shall be designed so that resonant vibration inherent in the fxture within the frequency range specified for the test shall be minor. The magnitude of the applied vibration shall be monitored on the test fixture near the specimen mounting points. The test specimen shall be mounted nigidly to the test fixture as specified and shall simulate as closely as possible the normal mounting of the specimen. A minimum of 200 mm (approx 8 in) of wire or cable shall be unsupported on both ends of the connector. For specimens with attached brackets, one of the vibration-test directions shall be parallel to the mounting surface of the bracket. Vibration input shall be monitored on the mounting fixture in the proximity of the support points of the specimen.
3.3.2 Test conditions V, VI and VII (random excitation conditions) Ihe specimen shall be mounted as specified. The orientation of the specimen or direction of application of the applied vibration motion shall be specified in one or more directions. If the order of application of the different directions is critical, it also shall be specified. Any special test fixtures or jigs required to run the test shall be specified in sufficient detail to assure reproducibility of the input motion applied to the specimen. These details shall include the dimensions, the materials, temper, etc, as applicable.
