RoHS - Restriction of Hazardous Substances：
The EU RoHS Directive (2011/65/EU) restricts the maximum allowable levels of lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants to 0.1% or 1000 ppm (except for cadmium, which is limited to 0.01% or 100 ppm) by weight of homogeneous material in electrical equipment and electronic products. In order to manufacture these products within or import into the European Union, manufacturers are responsible for providing due diligence documentation.
Since the adoption of EU RoHS, a number of other jurisdictions have, or are in the process of creating, similar Restriction of Hazardous Substances (RoHS) legislation including China RoHS, Korea RoHS, California RoHS, Taiwan RoHS, Turkey RoHS, and India RoHS.
RoHS Test Method:
IEC 62321: Electrotechnical products - Determination of levels of six regulated substances (lead. mercury. cadmium. hexavalent chromium. polybrominated biphenyls. polybrominated diphenyl ethers)
RoHS Test Requirement:
RoHS Directive 2002/95/EC and its subsequent amendments
RoHS Limit：
1. Lead 0.1% (1000 ppm)
2. Mercury 0.1% (1000 ppm)
3. Cadmium 0.01%（100 ppm)
4. Chromium (VI) 0.1% (1000 ppm)
5. Polybrominated biphenyls (PBB’s) 0.1% (1000 ppm)
6. Polybrominated diphenyl ethers (PBDE’s) 0.1% (1000 ppm)
