根据UL498要求,6个连接器应当按表93.1要求的插头连续插拔10次插入拔出无孔插脚后,按表93.1要求,一个重3磅(13N)力施加于垂直结合面对插头在保持一分钟后,位移不应当大于2mm。
根据表93.1要求,1-15R、5-15R、5-20R、应当使用1-15P插头测试。
93.3 Each of six devices is to be subjected to ten conditioning cycles of insertion and withdrawal of a standard solid-blade attachment plug that has American National Standard detent holes in accordance with Wiring Devices – Dimensional Specifications, ANSI/NEMA WD6, in rigidly mounted blades, following which the plug is to be fully reinserted into the device. The mating plugs are to have the configuration indicated in Table 93.1. A pull of 3 lbf (13 N) in a direction perpendicular to the plane of the face of the cord connector and tending to withdraw the plug from the device is then to be applied to the plug for 1 minute. The displacement of the plug shall not be greater than 0.079 inch (2 mm).
