IEC 62321 provided test methods of certain substances in electronic and electrical products.The first edition of IEC 62321:2008 was a single ‘stand-alone’ standard that includes an introduction,an overview of test methods,a mechanical sample preparation as well as various test method. May 17,2013IEC 62321: 2008 is split into a series of standards,while introducing new testing methods or apparatus, details below.
