RoHS is a compulsory standard formulated by EU legislation. Its full name is "restriction of hazardous substances". The standard was formally implemented on July 1, 2006. It is mainly used to standardize the material and process standards of electronic and electrical products, so as to make them more conducive to human health and environmental protection. The purpose of this standard is to eliminate lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products.
With regard to the recommendation of appropriate methods within the scope of RoHS directive, the International Electronic Technology Committee (IETC) proposed that X-ray fluorescence spectrometry analysis has the least sample preparation requirements, so it is suitable for rapid quantitative inspection.
