substances in
Electrical and Electronic Equipment, which is also known as the 2002/95/EC Directive. In 2005, the EU supplemented 2002/95/EC in the form of Resolution 2005/618/EC, which clearly stipulated the maximum limit values of six hazardous substances.
2. What are the hazardous substances? What is the standard?
Answer: In the first RoHS Directive issued by the EU, a total of six hazardous substances are listed, including: lead Pb, cadmium Cd, mercury Hg, hexavalent chromium Cr6+, polybrominated diphenyl ethers PBDE, and polybrominated biphenyls PBB. Other hazardous substances may be further added with the development of science and technology.
　　In Annex 1 of 2005/618/EC, Article 5.1 of 2002/95/EC on quality is supplemented, limiting the upper limit of the mass percentage of lead, mercury, hexavalent chromium, polybrominated diphenyl ethers (PBDE), and polybrominated biphenyls (PBB) to 0.1% (1000ppm), and the upper limit of cadmium content to 0.01% (100ppm).
