On February 13, 2003, the European Parliament and the European Commission issued the directive on waste electrical and electronic equipment (WEEE Directive) and the directive on restrictions on the use of certain hazardous substances in electrical and electronic equipment (RoHS directive)
　　According to RoHS directive and WEEE Directive, 102 kinds of products in ten categories are included in the management of hazardous substances restriction and scrap recovery. The first seven types of products are the main export electrical products in China. Including large household appliances, small household appliances, information and communication equipment, consumer products, lighting equipment, electrical and electronic tools, toys, leisure and sports equipment, medical equipment (except implanted or infected products), monitoring and control instruments, vending machines.
　　On December 3, 2008, EU issued the revised proposals of WEEE Directive (2002 / 96 / EC) and RoHS Directive (2002 / 95 / EC). The purpose of this proposal is to create a better regulatory environment, which is simple, easy to understand, effective and executable. The main contents of the revision of RoHS Directive are as follows:
　　1. The legal terms have been changed and the scope and definition of the directive have been clarified;
　　2. CE mark and EC declaration of conformity of imported products;
　　3. Medical devices, control and monitoring instruments will be included in the scope of RoHS directive by stages;
　　The six restricted hazardous substances remain unchanged, but four substances hexabromocyclododecane (hbcdd), 2-ethylhexyl phthalate (DEHP), butylbenzyl phthalate (BBP) and dibutyl phthalate (DBP) - require priority assessment to see if they will be included in the restricted substances category in the future
　　RoHS range:
　　Only for new products launched on July 1, 2006.
　　Including household incandescent lamps and light sources.
　　No violation of special directives or regulations on safety and health requirements -- vehicle directive; battery directive, 91 / 157 / EEC, 93 / 86 / EEC & 98 / 101 / EC
　　Does not include: medical equipment or monitoring equipment (WEEE Directive category 8, 9); maintenance spare parts put on the market before July 1, 2006; reuse products originally put on the market before July 1, 2006.
　　Restricted toxic substances:
　　·Heavy metals:
　　– lead;
　　– mercury;
　　– cadmium;
　　– chromium (VI) hexavalent.
　　·Some brominated flame retardants:
　　Polybrominated biphenyls (PBB's);
　　Polybrominated diphenyl ethers (PBDE's).
　　What is the maximum limit:
　　·Cadmium: 0.01% (100ppm);
　　·Lead, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers: 0.1% (1000ppm).
　　Six kinds of harmful substances
　　RoHS aims at all electrical and electronic products that may contain the above six harmful substances in the production process and raw materials, mainly including: white household appliances, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc., black household appliances, such as audio and video products, DVD, CD, TV receivers, it products, digital products, communication products, etc; Electric tools, electric electronic toys, medical electrical equipment.
　　1. Examples of lead (PB) using this material: solder, glass, PVC stabilizer
　　2. Mercury (mercury) examples of the use of this substance: thermostats, sensors, switches and relays, light bulbs
　　3. Examples of cadmium (CD < g é >) using this substance: switch, spring, connector, shell and PCB, contact, battery
　　4. Example of hexavalent chromium (Cr6 + < g è >) using this material: metal anticorrosion coating
　　5. Examples of polybrominated biphenyls (PBB) using this substance: flame retardant, PCB, connector, plastic shell
　　6. Examples of polybrominated diphenyl ether (PBDE) using this substance: flame retardant, PCB, connector, plastic shell
