Electrical and electronic products—Determination of six regulated substances(lead,mercury,cadmium,hexavalent chromium,polybrominated biphenyls,polybrominated diphenyl ethers)
Electrical and electronic products -
Determination of six regulated substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers)
1 Scope
This standard specifies the determination of the levels of lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr(VI)), and two 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 obtaining representative samples from finished electronic products to be tested for levels of regulated substances may be found in IEC/PAS 62596: 2009[1].
It is noted that the selection of the sample may affect the interpretation of the test results.
This standard does not determine:
——the definition of a “unit” or “homogenous material” as the sample;
——the disassembly procedure employed for obtaining a sample;
——assessment procedures.
Note 2: Further guidance on assessment procedures may be found in IEC/TR 62476: 2009[2].
