RoHS stands for the restriction of hazardous substances. It is a set of rules that restricts the use of certain hazardous substances in electrical and electronic equipment sold within the European Union. RoHS legislation came into effect on July 1, 2006. RoHS certification is required for all products intended for sale within the EU. RoHS legislation restricts the presence of specific hazardous substances in electronic equipment, which may pose a danger to human health or the environment. The goal of RoHS certification is to drastically reduce the amount of these substances in electrical and electronic products by banning their use, limiting them to certain quantities or requiring them to be removed through technical processes.
