If normal connector mating is dependent upon forces external 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.
每一试验样品都应准备好导线及其它材料，或作好模拟连接器的现场组装等工作。若连接器的连接方式需要依靠外力，那么这些外力与连接方式应尽可能模拟实际的状况（例如：印刷电路连接器）。若是通过的锁扣方式连接，那么也需采用相同的方式连接。

The specimen shall be attached to a fixture capable of transmitting the vibration conditions specified. The test fixture shall be designed so that resonant vibration inherent in the fixture 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 rigidly 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.
连接器试验样品应固定到能传递规定振动条件的夹具上，夹具的设计应能保证它的固有共振频率在试验所规定的频率范围内达到最小。在试验夹具上接近样品的地方监控所施加的振动强度。样品安装应尽可能模拟实际使用状况。在连接器尾端至少有200毫米（约8英寸）长的导线末被固定。对于带有安装托架的样品，振动试样的一个方向应平行于托架的安装面。在靠近样品支撑点的地方监控振动输入。

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.
按规定的方法安装样品，试验样品的位置或施加振动的方向应规定朝一个或一个以上的方向。如果朝不同方向施加的次序很重要，那就应该规定不同方向的先后顺序。对于进行试验所要求的任何特殊试验夹具或机架应充分详细规定，以保证施加到样品的输入量具有重复性，这些详细的规定包括尺寸、材料和温度等。
