GB/T30512-2014 Hazardous Substances Test
Project Introduction
GB/T 30512 is issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the Standardization Administration of China, which stipulates the substances prohibited in automobile complete vehicles and their parts and components.
Purpose and Significance
This standard is formulated to meet the requirements of the country to develop a circular economy, protect the environment and human health, build a resource-saving and environmentally friendly society, and improve the technical level of domestic sales vehicles.
This standard aims to prohibit the use of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in the research and development, production, import and sales of automobile products by domestic automobile manufacturers and automobile import agents. Restrictions on other toxic and hazardous substances are not specified in this standard.
Scope of Prohibited Substances
The substances prohibited in GB/T 30512 specifically refer to the following six substances
a) Lead or its compounds;
b) Mercury or its compounds;
c) Cadmium or its compounds;
d) Hexavalent chromium;
e) Polybrominated biphenyls (PBBs);
f) Polybrominated diphenyl ethers (PBDEs).

Except for the automobile parts and materials exempted within a certain period as specified in Appendix A, the mass percentage of lead, mercury, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs) in each homogeneous material of automobiles and their parts shall not exceed 0.1%, and the mass percentage of cadmium shall not exceed 0.01%.

Exemption requirements
According to the current status of China's automobile product technology and materials used, Appendix A stipulates the requirements for exemption of banned substances.
The automobile parts and materials, scope and exemption period specified in Appendix A will be adjusted in a timely manner according to the situation.
After the exemption period expires, the reuse and remanufacture of automobile products and parts will still be exempted.
Other exemption conditions

For automotive parts or materials not listed in Appendix A, if one of the following conditions is met, the automobile manufacturer or importer may apply for exemption of the product from banned substances:

a) The banned substances in the product cannot be replaced by other substances or materials due to technical reasons;

b) The banned substances will reduce the safety performance of the product after being banned;

c) The banned substances will affect the normal use and maintenance of the product after being banned;

d) The banned substances will significantly shorten the service life of the product after being banned;

e) The banned substances will significantly increase the production cost or sales cost of the product after being banned.
Detection methods for banned substances
The following four detection methods are recommended for the detection of the six banned substances proposed in this standard:
QC/T941-2013 Detection method for mercury in automotive materials;
QC/T942-2013 Detection method for hexavalent chromium in automotive materials;
QC/T943-2013 Detection method for lead and cadmium in automotive materials;
QC/T944-2013 Detection method for polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs) in automotive materials.
