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。, k2 ^! l$ `& J
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?

16.1 The leakage current of the appliance shall not be excessive and its electric strength shall be adequate.. H. F! i7 q- R/ O# { x
Compliance is checked by the tests of 16.2 and 16.3.8 f: I) c' D" G4 [2 V* l

The tests are carried out on the appliance at room temperature and not connected to the supply mains.4 e k/ e% d: ~, W+ O# _
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.; m9 y8 O U4 h1 v9 {! l G8 i* n% V
