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。+ F3 u k7 s1 q* ?( q
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?8 O, B |5 j$ a

16.1 The leakage current of the appliance shall not be excessive and its electric strength shall be adequate.- K0 I4 Y- d, H) W/ E
Compliance is checked by the tests of 16.2 and 16.3.

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.
