RoHS: the Restriction of the use of certain hazardous substances in electrical and electronic equipment.
The regulation is a European Union (EU) ban on the use of six hazardous substances in electronic products entering Europe.
In the RoHS standard, the maximum limits of six hazardous substances are: lead (Pb), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) maximum allowable content of 0.1%(1000ppm), cadmium (CD) is 0.01%(100ppm). This limit is the legal basis for determining whether a product complies with the RoHS directive.
