RoHS certification introduction

The full name of the RoHS directive is The Restriction of the use of Certain Hazardous Substances in Electrical and Electronic Equipment). In 2002, the European Union first put forward the concept of RoHS-the directive restricting the use of hazardous substances in electrical and electronic products (EEE).

Directive 2002/95/EC or RoHS: On July 21, 2011, the European Union restricted lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers ( PBDE) is used in the production process of certain electrical and electronic equipment sold in the European Union.

Directive 2011/65/EU or RoHS 2: On January 2, 2013, the EU restricted lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr VI), polybrominated biphenyls (PBB), polybrominated biphenyls Ether (PBDE), bis(2-ethylhexyl) phthalate (DEHP), tolylbutyl phthalate (BBP), dibutyl phthalate (DBP), phthalic acid Diisobutyl ester (DIBP) (abbreviated as o-benzene 4P).

In addition to the European Union, other countries and regions around the world such as China, California, Singapore, India, UAE, Turkey, etc. have also introduced RoHS control requirements, making RoHS the basic entry barrier for electronic and electrical products to enter the global market.
