1 Scope This standard specifies the maximum allowable content of restricted substances in electrical and electronic products and the corresponding compliance criterion rules. This standard is applicable to the control of such restricted substances in electrical and electronic products as plumbum (Pb), hydrargyrum (Hg), cadmium (Cd), chromium VI (Cr (VI)), polybrominated biphenyl (PBB) and polybrominated biphenyl ethers (PBDE). 2 Normative References The following referenced documents are indispensable for the application of this document. For dated reference, only the edition cited applies. For undated reference, the latest edition of the normative document (including any amendment) applies. GB/T 26125-2011 "Electrical and Electronic Products - Determination of Six Regulated Substances (Lead, Mercury, Cadmium, Hexavalent Chromium, Polybrominated Biphenyls, Polybrominated Diphenyl Ethers)" (IEC 62321: 2008, IDT) 3 Terms and Definitions For the purpose of this standard, the following terms and definition apply. 3.1 Restricted substances Substances required by laws and regulations or customers to be under restricted use in electrical and electronic products. 3.2 Electrical and electronic products (EEP) Equipment and auxiliary products operating by way of current or magnetic field and then generating, transmitting and measuring the said current and magnetic field, with rated operating voltage not exceeding 1500V under direct current and 1000V under alternating current. 3.3 Homogeneous materials Materials composed of one kind or several kinds of substances, of which each part is uniform. 3.4 Components Construction units in electrical and electronic products, with certain function or application purposes. Note: Such as components and parts, case, bracket, screw, switch and conductor etc. 3.5 Test units Samples that can be directly submitted to be tested without the necessary for further disassembling. 4 Limit Requirements As for plumbum, hydrargyrum, chromium VI, polybrominated biphenyl and polybrominated biphenyl ether in homogeneous materials constituting electrical and electronic products, the content of each said restricted substance shall not exceed 0.1% (mass fraction), and the cadium content shall not exceed 0.01% (mass fraction).
