Introduction of ROHS certification
RoHS is the English abbreviation of the " Restriction of the use of certain hazardous substances in electrical and electronic equipment ".
Harmful Substance
RoHS lists a total of six harmful substances, including: lead Pb , cadmium Cd , tribute Hg ,Hexavalent chromium Cr6 + , polybrominated diphenyl ether PBDE , polybrominated biphenyl PBB .
Authentication role
The purpose is to prevent the incorporation and use of substances that are prohibited from being used in the components and materials of electronic and electrical equipment, environmentally controlled substances, planned to be abolished, and reduced substances (harmful substances). Protect the global environment and mitigate the deteriorating impact on ecosystems, protect human health, and maintain the sustainable and healthy development of human society.
RoHS Standard Implementation Time
The EU in 2006 Nian 7 Yue 1 date of implementation RoHS , when the use of or containing heavy metals and polybrominated diphenyl ethers PBDE , polybrominated biphenyls PBB and other flame retardants in electrical and electronic products will not be allowed to enter the EU market.
Products covered by RoHS standards
RoHS targets all electrical and electronic products that may contain the above-mentioned six hazardous substances in the production process and raw materials, mainly including:
1. Large household appliances: refrigerators, washing machines, microwave ovens, air conditioners, white goods, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc.
2. Small household appliances: vacuum cleaners, electric irons, hair dryers, ovens, clocks, black appliances, such as audio and video products, DVDs , CDs , television receivers, IT products, digital products, communication products, etc.
3 , IT and communications equipment: computers, fax machines, telephones, mobile phones, power tools; electric and electronic toys; medical electrical equipment.
4. Civil equipment: radio, television, video recorder, musical instrument, etc.
5. Lighting equipment: Fluorescent lamps other than domestic lighting, lighting control devices
6. Power tools: electric drill, lathe, welding, sprayer, etc.
7. Information technology and telecommunications equipment (although infrastructure equipment is exempted in some countries) 4 . Consumer equipment. 5 . Lighting equipment including bulbs.
6. Electronic and electrical tools. 7 toys, leisure and sports equipment.
8. Medical devices (currently exempted)
9. Monitoring and control instruments (currently exempt)
10. Vending machines.
11. Semiconductor devices.
RoHS standard test method
Send related products to professional laboratories for testing, and test the products after splitting them into a single material with uniform materials, including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB) , polybrominated diphenyl ethers (PBDE) Wait for the six hazardous substances to meet the requirements of the RoHS Directive. If they comply, you will get RoHS conformity reports and certificates. If they do not, you will have to find another product that meets the requirements to replace them.
