Series of IEC 62321 2013 Standards Published
In 2008, the International Electrotechnical Commission (IEC) published the six kinds of regulated substances (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers) in electrical and electronic products about a concentration measurement with international standards IEC 62321: 2008. It provides an harmonized standard to the regulated substances testing of the electrical and electronic products, and promotes vigorously to the global electronics industry on RoHS compliance.
In order to better adapt to RoHS requirements of the electrical and electronics industry, IEC has been committed to the revision of current standards in recent years.
In June 2013, the latest 2013 version of IEC 62321-1, -2, -3-1, -3-2, -4 and -5 are firstly released. Compared with the 2008 version of the standard, the changes in the 2013 edition mainly include the separation of standard into individual documents, and the test equipment combustion ion chromatography (C-IC) and cold vapor atomic fluorescence spectrometry (CV-AFS) have been introduced (see Table 1).
