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。5 a( P( j6 L% F3 w% o4 o. W" c
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?& n) E+ x5 [* ? M: F
16 Leakage current and electric strength
- t# s) A; L7 G% O16.1 The leakage current of the appliance shall not be excessive and its electric strength shall be adequate.# g, U/ ]0 N* t5 N
Compliance is checked by the tests of 16.2 and 16.3.3 `5 H0 b6 M+ r1 }( T
Protective impedance is disconnected from live parts before carrying out the tests.
