In many countries all over the world
45、 this has resulted in the adaptation of regulations affecting wastes, substances and energy use of electrotechnical products. The use of certain substances such as lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr(VI) contained in inorganic and organic compounds, and two types of bromin
46、ated flame retardants, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) in electrotechnical products, is regulated in current and proposed regional legislation. The purpose of IEC 62321 is therefore to provide test methods that will allow the electrotechnical industry to dete
47、rmine the levels of regulated substances Pb, Hg, Cd, Cr(VI) and their compounds, as well as PBB and PBDE in electrotechnical products on a consistent global basis. BS EN 62321:200962321 IEC:2008 9 ELECTROTECHNICAL PRODUCTS DETERMINATION OF LEVELS OF SIX REGULATED SUBSTANCES (LEAD, MERCURY, CADMIUM,
48、HEXAVALENT CHROMIUM, POLYBROMINATED BIPHENYLS, POLYBROMINATED DIPHENYL ETHERS) 1 Scope IEC 62321, which is an International Standard, specifies the determination of the levels of lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr(VI) contained in inorganic and organic compounds, and two
49、types of brominated flame retardants, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) contained in electrotechnical products. This standard 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. NOTE 1 Further guidance on
