Restriction of Hazardous Substance (RoHS) Directive

RoHS is an European directive imposing restrictions on the use of certain hazardous substances in electrical and electronic equipment. It is meant to reduce health and environmental risks by restricting the use of listed substances in electronic components. Unless an exception applies, the concentration thresholds should not be exceeded for the following:

  • Cadmium and cadmium compounds
Cd < 100 ppm <0.01%
  • Hexavalent chromium             
Cr6+ <1000 ppm <0.1%
  • Mercury or mercury compounds
Hg <100 ppm <0.01%
  • Lead or lead compounds
Pb <1000 ppm <0.1%
  • PolyBrominated DiphenylEthers
PBDEs <1000 ppm <0.1%
  • PolyBrominated Biphenyls
PBBs <1000 ppm <0.1%


These thresholds apply to any homogenous materials or component that cannot be mechanically disjointed such as wires, plastics, solders, or alloys.
