RoHS is a mandatory standard developed by the European Union legislation, its full name is "Restriction of the use of certain hazardous components in electrical and electronic equipment directive" (Restriction of Hazardous Substances). The standard has been formally implemented on July 1, 2006, mainly used to regulate the materials and process standards of electrical and electronic products, so that it is more conducive to human health and environmental protection. The purpose of the standard is to eliminate lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs) in electrical and electronic products***, with a focus on lead, the content of which should not be more than 0.1%. The main sources of lead involved are the following categories.
RoHS scope:
Only for July 1, 2006 onwards on the market for new products.
Including incandescent lamps and light sources for household use.
Not to violate the special safety and health requirements of specific directives or regulations - Vehicle ELV, Automotive Directive; Battery Directive, 91/157/EEC, 93/86/EEC & 98/101/EC
Excluding: medical devices or monitoring equipment (WEEE Directive No. 8) equipment (WEEE Directive Categories 8 and 9); spare parts for repairs placed on the market before July 1, 2006; reused products originally placed on the market before July 1, 2006.
Restricted Toxic Substances:
-Heavy Metals:
-Lead;
-Mercury;
-Cadmium;
-Chromium (VI) hexavalent chromium.
-Certain brominated flame retardants:
Polybrominated biphenyls (PBB's);
Polybrominated diphenyl ethers (PBDE's). ethers (PBDE's).
The maximum limits are:
-Cadmium: 0.01% (100ppm);
-Lead, Mercury, Hexavalent Chromium, Polybrominated Biphenyls, Polybrominated Diphenyl Ethers: 0.1% (1000ppm).
Six categories of hazardous substances
RoHS for all production processes and raw materials may contain the above six hazardous substances in electrical and electronic products, mainly including: white goods, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc., black appliances, such as audio, video products, DVDs, CDs, TV receivers, IT products, digital products, communication products, etc.; power tools, power tools, power tools, power tools and digital products. Black appliances, such as audio and video products, DVD, CD, TV receivers, IT products, digital products, communication products, etc.; power tools, electric and electronic toys, medical and electrical equipment.
1. Lead (Pb) Examples of the use of the substance: solder, glass, PVC stabilizers
2. Mercury (Hg) (mercury) Examples of the use of the substance: thermostats, sensors, switches and relays, light bulbs
3. Cadmium (Cd <gé>) Examples of the use of the substance: switches, springs, connectors, housings, and PCBs, Contacts, batteries
4. Hexavalent chromium (Cr 6+ <gè>) Examples of the use of the substance: metal-attached corrosion coatings
5. Polybrominated biphenyls (PBB) Examples of the use of the substance: Flame retardant, PCBs, connectors, plastic housings
