The purpose of RoHS testing is to limit the use of hazardous substances in electronic and electrical products, to promote the environmentally friendly regeneration and final treatment of waste electronic and electrical equipment, and to ensure human health. The directive stipulates the limit requirements for toxic and hazardous substances, and also requires countries to formulate corresponding penalties in accordance with the "Directive on Restrictions on the Use of Certain Hazardous Substances in Electronic and Electrical Equipment" No. 2002/95/EC. \x0d\EU RoHS 1.0: In 2006, EU legislation established a mandatory standard RoHS Directive, which is mainly used to standardize the material and process standards of electronic and electrical products. It aims to eliminate lead, mercury, cadmium and hexavalent chromium in electronic and electrical products. , polybrominated biphenyls and polybrominated diphenyl ethers*** 6 substances. \x0d\EU RoHS 2.0: In 2015, the European Union issued Directive (EU) 2015/863 in its official journal to amend Annex II of RoHS 2.0 (2011/65/EU), officially including four phthalates (DEHP). , BBP, DBP, DIBP) are listed in RoHS 2.0 and listed in Appendix II. So far, Appendix II*** has ten mandatory controlled substances. After the directive is issued, each EU member state must convert the directive into national regulations and implement it before December 31, 2016. \x0d\Nationally promoted RoHS: According to the "Implementation Arrangements for the Conformity Assessment System for Restricted Use of Hazardous Substances in Electrical and Electronic Products" issued by the State Administration for Market Regulation and the Ministry of Industry and Information Technology in 2019 No. 23 (hereinafter referred to as the "Implementation Arrangements"), Products shipped and imported after November 1, 2019 that are included in the "Restricted Use of Hazardous Substances in Electrical and Electronic Products Management Catalog (First Batch)" should meet the requirements of the "Implementation Arrangement". \x0d\ROHS testing has CMA qualification unit:\x0d\Zhongke Testing\x0d\ROHS testing control scope:\x0d\All electronic, electrical appliances, medical, communications, toys, security information and other products, it not only includes complete products, It also includes the parts, raw materials and packaging used in the production of the complete machine, which is related to the entire production chain\x0d\RoHS testing principle:\x0d\Split the product according to the material, and use different materials to detect hazardous substances separately. Generally speaking: ·\x0d\Metal materials need to be tested for four harmful metal elements such as (Cd cadmium/Pb lead/Hg mercury/Cr6 hexavalent chromium); \x0d\In addition to testing these four harmful heavy metal elements, plastic materials also need to be tested Detection of brominated flame retardants (polybrominated biphenyl PBB/polybrominated diphenyl ether PBDE)
