RoHS is a mandatory standard developed by the EU legislation, which stands for "Restriction of the use of certain hazardous substances in electrical and electronic equipment directive" (Restriction of Hazardous Substances). The standard was July 1 formally implemented in 2006 to regulate the materials and process standards electrical and electronic products, making it more conducive to human health and the environment. The purpose of the standard is to eliminate electrical and electronic products for lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers total of six substances, and focus on the provisions of the lead content does not exceed 0.1%. Which involves the main source of lead in the following categories.

European Parliament and the European Commission on February 13, 2003 issued the "Waste Electrical and Electronic Equipment Directive" (referred to as the "WEEE Directive") in its "Official Gazette" and on "Electrical and Electronic Equipment Restrictions on the Use of Certain Hazardous Substances Directive" ( referred to "RoHS Directive") ROHS mark
"RoHS Directive" and the "WEEE Directive" provisions in the Restriction of Hazardous Substances Management and scrap recycling management are ten categories of 102 kinds of products, the first seven categories of major export products are electrical products. Including large household appliances, small home appliances, information and communications equipment, consumer products, lighting equipment, electrical and electronic tools, toys, leisure and sports equipment, medical equipment (except to be implanted or infected products) monitoring and control instruments , vending machine.
December 3, 2008, the EU issued the ROHS directive (2002/95 / EC) of the revised proposal. The purpose of this proposal is to create a better regulatory environment that is simple, understandable, effective and enforceable regulations. The main contents of the revised RoHS Directive are:
1. Change the legal wording to clarify the scope and definition of instruction;
2. The introduction of the product CE mark and EC declaration of conformity;
3. phased medical equipment, control and monitoring equipment into the scope of ROHS Directive;
No change of six hazardous substances restricted, but the four substances - Six HBCD (HBCDD), phthalic acid (2-ethylhexyl) (DEHP), butyl benzyl phthalate (BBP ) and dibutyl phthalate (DBP) - requires priority evaluation, in order to examine whether the scope of the future inclusion of regulated substances ROHS range: for only from July 1, 2006 to market new products.
Including household and incandescent light sources.
We should not violate special specialized instruction on safety and health requirements or provisions --Vehicle ELV, car instruction; Batteries Directive, 91/157 / EEC, 93/86 / EEC & 98/101 / EC
Not included: medical equipment or monitoring equipment (WEEE Directive category 8,9); in 2006 served before July 1 Spare Parts market; July 1, 2006 to market the original product reuse.
Limit toxic substances: · heavy metals: -Lead lead; -Mercury mercury; -Cadmium cadmium; -Chromium (VI) hexavalent chromium certain brominated flame retardants: PBB -Polybrominated biphenyls (PBB's); polybrominated diphenyl ethers -Polybrominated . diphenyl ethers (PBDE's) highest limit indicators are: Cd: 0.01% (100 ppm); · lead, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers: 0.1% (1000 ppm).
