Requirements of Concentration Limits for Certain Restricted Substances in Electrical and Electronic Products
1 Scope
This document specifies the maximum allowable content of restricted substances in electrical and electronic products and the corresponding compliance criterion rules.
This document 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), polybrominated biphenyl ethers (PBDE), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP), butyl benzyl phthalate (BBP) and di(2-ethylhexyl) phthalate (DEHP).
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 39560 (all parts) "Determination of Certain Substances in Electrical and Electronic Products"

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.
