Dear，

We use ISO7820 and ISO7840，UL 61010-1 2018 standard contains the definition of 5s - as follows, the current value of 5700VRMS 1min is OK, we do need the AC value of 5S to define our products.

Could you help supply the value VacRMC of 5s, thanks.

Hi Hui,

ISO7820FDWWR & ISO7840FDWWR can definitely pass 7400 V AC for 5 seconds. Also, ISO7842 definitely passes 7400 V AC for 5 seconds. You can refer to isolation capacitor life time projection in ISO7842 datasheet at:
