|The "Restriction of Hazardous Substances Directive," most commonly referred to as RoHS, is an initiative that was proposed in 2003 by the European Union as a method to stop the sales of items that include six different hazardous materials. Since the time of RoHS enactment (July 2006) the United States and Canada have also enacted much of the compliance rules originally set forth by the EU. It is a directive adopted by member countries of the European Union in 2004 controlling the use of six hazardous materials in the manufacturing of electronic equipment. It is closely linked with the Waste Electrical and Electronic Equipment Directive, also known as WEEE. The RoHS helps prevent dangerous chemicals from reaching landfills in large numbers, while providing additional safety to consumers.
RoHS mandates controlled usage of harmful substances in electrical and electronic manufacturing processes. Being ROHS Compliant is necessary and mandatory for all businesses that manufacture or market their electrical and electronic products in the EU. There are no exemptions, and even third-party suppliers of components, resellers and distributors have to abide by the laws. Non-compliance to RoHS is strictly penalized. The listed substances have been identified as posing the most significant threats to worker safety in manufacturing procedures, and to the environment when goods containing these harmful substances are disposed of in landfills. It is very difficult to test every piece of electronic equipment for RoHS compliance. According to RoHSGuide.com, X-ray fluorescence is used to verify that electronics do not contain prohibited substances.
