在60335-1标准中分别有13.2条的工作温度下的泄漏电流测试和16.2条的在潮湿处理后的泄漏电流测试。" [! ]. H0 l) r
在13.2条的测试比较好理解,那对于16.2条的测试各位是如何做的呢?

16.2 An a.c. test voltage is applied between live parts and accessible metal parts that are connected to metal foil having an area not exceeding 20 cm × 10 cm in contact with accessible surfaces of insulating materials.
