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。" n0 k6 ], S- k( G# ?2 D
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?

, Y, {+ a1 E$ K16.1 The leakage current of the appliance shall not be excessive and its electric strength shall be adequate." Z `8 z3 t4 |, N7 O
Compliance is checked by the tests of 16.2 and 16.3.
/ l" X0 [' i7 Y' SProtective impedance is disconnected from live parts before carrying out the tests.

( t4 e7 c' R# `0 m) R$ ^) i* I16.2 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., s5 b5 s Y0 \( K8 K
The test voltage is
4 Q' _5 q2 h$ q5 ~* V A. B– 1,06 times rated voltage, for single-phase appliances;$ u+ ~8 p. i% A$ n+ f: R
– 1,06 times rated voltage, divided by 3 , for three-phase appliances.! L; C$ F/ {/ ^ m- e+ Y% s6 l
The leakage current is measured within 5 s after the application of the test voltage. |
