RoHS is the English abbreviation of "The Restriction of the use of certain hazardous substances in electrical and electronic equipment" (The Restriction of the use of certain hazardous substances in electrical and electronic equipment), also translated as "Prohibition on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment" Restriction on Hazardous Substances in Electronic Products. This regulation is a European Union (EU) ban on the use of six hazardous substances in electronic products entering Europe.
The RoHS standard requires manufacturers to ensure that the following six hazardous substances are not included or used to a minimum in the production and handling of products: lead (Pb) (affects the central nervous system and renal system), cadmium (causing kidney failure) ), mercury Hg (affects the central nervous system and renal system), hexavalent chromium Cr+6 (hereditary gene defect) and other heavy metals, as well as polybrominated diphenyl ethers PBDE (also known as polybromophenyl ethers) and polybrominated biphenyl PBB (also known as polybrominated biphenyl ethers) Benzene) and other flame retardants (can cause cancer and fetal abnormalities).
The RoHS standard stipulates that the maximum limits for six hazardous substances are: lead (Pb), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyl (PBB), polybrominated diphenyl ether ( The maximum allowable content of PBDE is 0.1% (1000ppm) and cadmium (cd) is 0.01% (100ppm). This limit is the legal basis for determining whether a product complies with the RoHS directive.
RoHS targets all electrical and electronic products that may contain the above six hazardous 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.; And "black appliances": such as speakers, CD players, video recorders, DVD players, set-top boxes, etc.; and IT products: such as computer parts, digital products, communication products, etc.; in addition, it also includes power tools, electric electronic toys, medical electrical appliances Equipment etc.
The RoHS standard was officially implemented on July 1, 2006. Judging from the purpose of the EU's formulation of the RoHS standard, consumers will be the biggest beneficiaries of the standard. After the implementation of the RoHS standard, users can reduce the chance of being harmed by harmful substances hidden in electrical and electronic products.
In electronic components, the main thing is whether the tube leg plating is lead or lead-free. If the IC is lead-free printing, there will be a white spot. If the original factory does not conduct RoHS management at all, downloading the report is just a lie. If the customer detects that it is not environmentally friendly, it will be a big deal to make a claim.
Departments that can conduct RoHS testing can issue relevant reports. You can find it in BAIDU:
