Applications
- Industrial
- IEC 60950 (transitioning to IEC 62368) requires 8 mm for higher working voltages
- IS2 also extends qualification to IEC 62368
- Medical Applications
- IEC 60601 requires 8 mm for 250 VRMS for 2 MOPP (two means of patient protection, most stringent requirement) or to use conformal coating
- IS2 extends use from 125 VRMS to 250 VRMS with no coating
