These are originally IEC standards: both are multi-part, but here are the details of relevant Parts of each, from the public part of the IEC web site: Project : IEC 61558-2-16 Ed. 1.0 [not yet published] Committee TC96 Title (English): Safety of power transformers, power supplies, reactors, and similar products - Part 2-16: Particular requirements for switch mode power supplies and transformers for switch mode power supplies IEC 61204-7 (2006-07) Committee: SC22E Title (English): Low-voltage power supplies, d.c. output - Part 7: Safety requirements 61558-1 is about safety and 61204-7 is about safety! Different technical committees are responsible, so it appears that the Standards Management Board may have to ask some questions about 'parallel work'. -- OOO - Own Opinions Only.
