IEC 62321-1 refers to the sample as the object to be processed and measured. The nature of the sample and the manner in which it is acquired is defined by the entity carrying out the tests and not by this standard. It provides guidance on the disassembly procedure employed for obtaining a sample. This first edition of IEC 62321-1 is a partial replacement of IEC 62321, forming a structural revision and replacing Clauses 1 to 4. IEC 62321-1 has the status of a horizontal standard in accordance with IEC Guide 108.
