RoHS is the acronym for Restriction of Hazardous Substances. RoHS originated in the European Union and restricts the use of specific hazardous materials found in electrical and electronic products. All applicable products in the EU market after July 1, 2006 must pass RoHS compliance. Electrical and electronic manufacturers whose products are sold in the EU or some additional countries which have adopted RoHS must achieve RoHS compliance. They must also comply with the related WEEE directive, which defines disposal and recycling conditions for this equipment.
