On july21,2011, the EU restricted the use of lead (PB), mercury (Hg), cadmium (CD), hexavalent chromium (cr6+), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) in the production of electrical and electronic equipment sold in the EU.

2011/65/eu directive or RoHS 2: on January 2, 2013, EU restricted lead (PB), mercury (Hg), cadmium (CD), hexavalent chromium (CR VI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), di (2-ethylhexyl) phthalate (DEHP), toluene butyl phthalate (BBP), dibutyl phthalate (DBP), diisobutyl phthalate (DiBP) (hereinafter referred to as "phthalic 4P").

In addition to the European Union, other countries and regions around the world, such as China, California, Singapore, India, the United Arab Emirates and Turkey, have also successively introduced RoHS control requirements, making RoHS the most basic access threshold for electronic and electrical products to enter the global market.

Test items and regulatory requirements

The content of each homogeneous material shall not exceed the following limits:

Lead: limit 1000ppm

Mercury: limit 1000ppm

Hexavalent chromium: limit 1000ppm

Cadmium: limit 100ppm

Polybrominated biphenyls (PBB): limit 1000ppm

Polybrominated diphenyl ether (PBDE): limit 1000ppm

Di (2-ethylhexyl) phthalate (DEHP): limit 1000ppm

Dibutyl phthalate (DBP): limit 1000ppm

Butyl benzyl phthalate (BBP): limit 1000ppm

Diisobutyl phthalate (DiBP): 1000ppm

Applicable product range

RoHS directive covers a wide range of products, covering almost all electronic and electrical products and their raw materials:

Application materials

1. Only heavy metal detection: about 5-10g for solid and 5-10ml for liquid;

2. Only brominated flame retardants are tested: about 10-20g for solid and 10-20ml for liquid;

3. Detection of heavy metal and organic pollutants: provide about 20-30g samples;

4. Detection of other organic pollutants: provide about 30g sample;

5. Only the samples of the coating (coating) parts shall be tested, and the approximate weight of the material parts of the coating (coating) shall be indicated; If the weight of the coating (coating) part fails to meet the requirements of sample delivery, the coating (coating) raw materials shall be provided.
