新版61558 18.5章节漏电流测试

在新版的61558-1中，18.5章节，关于漏电流的测试，
if frequencies above 30 kHz are involved, measurement of touch
current shall include measurement with regard to electric burn effects in addition to the
measurements of Figure J.1. For the burn effects, the unweighted r.m.s. value of the touch
current is relevant. Unweighted touch current is calculated from the r.m.s. voltage U1,
measured across the 500 Ω resistor of Figure J1 Annex J.

也就是说如果开关电源的频率超过30KHz的话，U1就要被测试，还是RMS值， 问题是限值是多少？
请各位大侠帮助。

U1/500
限值参考61558-1

感谢您的回复，你的意思是限值是0.5ma,
但是实际上U1比U2要大的多，如果还是按照U2的要求的话，基本上无法通过测试。
