* RoHS Directive
The RoHS (Restriction of Hazardous Substances (in electrical and electronic equipment)) Directive is an environmental directive enacted
to regulate the use of designated chemical substances (lead, cadmium, hexavalent chromium, mercury, polybrominated biphenyls and
polybrominated diphenylether) in electrical equipment. All household products subject to this Directive and sold in Europe from July 1,
2006 are legally bound to comply with the RoHS Directive.
