IEC 62321 Testing
Electro technical products – Determination of levels of six regulated substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers)
IEC 62321 Scope:
IEC 62321 testing 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 types of brominated flame retardants, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) contained in electrotechnical products.
EN 62321 testing 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 the future IEC Publicly Available Specification (PAS) for sampling disjointment.
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.
