IEC 62321 provides 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, mechanical sample preparation as well as various test methods. May 17, 2013 IEC 62321: 2008 is split into a series of standards, while introducing new testing methods or apparatus, details are below.
IEC 62321-7-2 Hexavalent chromium – Determination of hexavalent chromium (Cr(VI)) in polymers and electronics by the colorimetric method Main changes: Employs organic solvent to dissolve or swell the sample matrix, followed by an alkaline digestion procedure to extract Cr(VI) from samples.
IEC 62321-8 Phthalates in polymers by gas chromatography-mass spectrometry (GC-MS), gas chromatography-mass spectrometry using a pyrolyzer/thermal desorption accessory (Py/TD-GC-MS) Main changes: New method （ two normative and two informative techniques for the determination of di-isobutyl phthalate ）
