In 2000, when cadmium was found in the cables of some game machines sold in the Dutch market, people first noticed that electrical and electronic equipment contained heavy metals harmful to human health. In fact, solder and ink printed on packaging boxes widely used in the production of electrical and electronic products all contain harmful heavy metals such as lead.
Second, the ROHS testing standard is 20 1 1/65/EU, so there are six items required to be tested by European RoHS 201/65/EU, namely:
1, lead
2. cadmium
3. Mercury
4. Hexavalent chromium (Cr6+)
5. Polybrominated biphenyl
6. Polybrominated diphenyl ethers
The contents of six harmful substances in the above homogeneous substances should not exceed the limit value, of which cadmium is 0.0 1% and the rest is 0. 1%. Common white appliances in our life, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc. Black household appliances, such as audio-visual products, DVDs, CDs, TV receivers, IT products, digital products, communication products, etc. Electric tools, electric toys, medical electrical equipment, etc. These six harmful substances may be contained in the production process and raw materials, so it is impossible to enter the EU market without passing the test, because RoHS is a mandatory standard formulated by EU legislation.
Three. 201the latest news on June 4th, May: The European Union issued the revised RoHS 2.0 directive, which formally brought four kinds of toxic and harmful substances (DEHP, BBP, DBP and DIBP) into the control scope of RoHS 2.0, and added four kinds of toxic and harmful substances with restricted use in 10 as follows:
1, lead
2. cadmium
3. Mercury
4. Hexavalent chromium (Cr6+)
5. Polybrominated biphenyl
6. Polybrominated diphenyl ethers
7. Diisobutyl phthalate (DIBP)
8. Phthalic acid (2- ethylhexyl ester) (DEHP)
9. Dibutyl phthalate
10, butyl benzyl phthalate (BBP)
