A couple of very basic questions for the group: 1) My understanding of the interrelation between different IEC standards is that IEC 60664-1, Insulation coordination for equipment within low-voltage systems, is considered to be a basic standard for creepage & clearance requirements, and while some end-product standards (like 61010 & 60950) might have insulation requirements specific to the end-product environment or application, IEC 60664 is the beginning point for the insulation, creepage & clearance requirements. Is that understanding correct, or am I missing something? 2) If I am looking at an IEC end-product standard, and there is an insulation issue that is not clearly defined, is it acceptable to look at the IEC 60664 series for guidance?
