If you are involved in the sale or manufacture of electric or electronic equipment or parts, you must know RoHS regulations. The definition and aim of the RoHS directive is quite simple. The RoHS directive aims to restrict certain dangerous substances commonly used in electronic and electronic equipment. Any ROHS Compliant component is tested for the presence of Lead, Cadmium, Mercury, Hexavalent chromium, Polybrominated biphenyls, and Polybrominated diphenyl ethers. For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. RoHS compliance means acting in full accordance with RoHS regulations and documenting your test for RoHS controlled substances.
RoHS and other efforts to reduce hazardous materials in electronics are motivated in part to address the global issue of consumer electronics waste. As newer technology arrives at an ever increasing rate, consumers are discarding their obsolete products sooner than ever. This waste ends up in landfills in many places of the world. RoHS and other environmental laws are in contrast to historical and contemporary law that seeks to address only acute toxicology, which is direct exposure to large amounts of toxins causing severe injury or death. Compliance is the responsibility of the company that puts the product on the market, as defined in the Directive.
