The RoHS Directive restricts the use of certain hazardous substances in electrical and electronic equipment. Within Germany, it is transposed into national law by ElektroStoffV (German Electronic Equipment Substances Ordinance). The aim is to regulate, restrict and, where possible, avoid the use of harmful or hazardous substances. Hazardous substances include mercury, lead, hexavalent chromium and cadmium. Plasticisers and brominated flame retardants are also affected. The directive provides for a gradually extended list of hazardous substances. As a distributor or manufacturer, you may only use these substances in electrical and electronic equipment up to certain maximum concentration values.
