RoHS I*** lists six hazardous substances, including: Lead Pb, Cadmium Cd, Mercury Hg, Hexavalent Chromium Cr6+, Polybrominated Diphenyl Ethers PBDE, and Polybrominated Biphenyls PBB.
RoHS standard 2005/618/EC resolution stipulates the limit value of the six hazardous substances, which lead (Pb), mercury (Hg), hexavalent chromium (Cr6+), polybrominated Biphenyl (PBB), polybrominated diphenyl ether (PBDE) maximum allowable content of 0.1% (1000ppm), cadmium (cd) for 0.01% (100ppm), the limit value is the development of the product is in line with the RoHS Directive legal basis.
The RoHS Directive involves a fairly wide range of products, covering almost all electronics, electrical appliances, medical, communications, toys, security information and other products, which not only includes the whole product, but also includes the production of the whole machine used in the production of parts and components, raw materials and packaging parts, related to the entire production chain.
Expanded Information:
RoHS is aimed at all electrical and electronic products that may contain the six hazardous substances mentioned above during the production process and in the raw materials, including: white goods, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc., and black goods, such as audio and video products, DVDs, CDs, TV receivers, IT products, and so on. Black appliances, such as audio and video products, DVDs, CDs, TV receivers, IT products, etc.
