Chemical Testing
RoHS Testing

With an aim to tackle with the associated environmental problems, EU Parliament and European Council announced the directive of Waste of Electrical and Electronic Equipments (WEEE) and Restriction of Hazardous Substances (RoHS) on 27th January 2003. At the same time, China, Japan, Korea and US have also established their own Green regulation.


The European directive on the Restriction of Hazardous Substances (RoHS) holds electrical and electronic equipment companies directly responsible for the chemical compliance of their products. This means all products must conform to strict standards, provide extensive compliance documentation, and ensure that electrical and electronic products sold in the EU do not contain lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs) above the legal threshold. Manufacturers, owners, retailers, and importers alike need to ensure that their products comply in order to be distributed and sold in the EU.
