GB/T 39560.701-2020 《Determination of certain substances in electrical and electronic products—Part 7-1:Hexavalent chromium—Presence of hexavalent chromium [Cr(VI)] in colourless and coloured corrosion-protected coatings on metals by the colorimetric method》 Related products

GB/T 39560.701-2020 for electronic and electrical products, focusing on the determination of hexavalent chromium. This part uses Colorimetry, which is specially used to detect hexavalent chromium in colorless and non-ferrous anti-corrosion platings on metals. The standard details the determination principle, stipulates the reagents, instruments, etc., covers Sample Handling, testing operation procedures, and clarifies the calculation and reporting methods of results. Through standardized testing, it helps to control the mass of electronic and electrical products, ensure the environmental friendliness of products, and reduce the potential harm of hexavalent chromium to the environment and human body.
