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。

16.1 The leakage current of the appliance shall not be excessive and its electric strength shall be adequate.. R0 \% D5 ^ g& {# [+ a( R! g4 z4 F7 ?
Compliance is checked by the tests of 16.2 and 16.3.

The tests are carried out on the appliance at room temperature and not connected to the supply mains.

– 1,06 times rated voltage, divided by 3 , for three-phase appliances.' V1 e& C5 f4 v/ f# q4 M( i
The leakage current is measured within 5 s after the application of the test voltage. |
