IEC 62321 Standard – 2013 Edition
The 2013 versions of IEC 62321-1, -2, -3-1, -3-2, -4, and -5 have passed the Final Draft International Standard (FDIS) stage and are now officially published. IEC 62321, a standard concerning the determination of specific hazardous substances in electronic products, outlines test methods for determining the concentration of hazardous chemicals in products below the levels set forth in the EU RoHS Directive. As with previous standards, the 2008 version of IEC 62321 underwent a maintenance cycle, and the latest version incorporates best practices and advanced technologies to ensure consistency and reliability in testing procedures, meeting the standards' development requirements. The most significant change in the 2013 version is the splitting of the document into a series of standards to facilitate maintenance, while also introducing new test methods and instruments, such as combustion-ion chromatography (C-IC) and cold vapor atomic fluorescence spectrometry (CV-AFS).
