What is RoHS test?

The purpose of RoHS testing is to limit the use of harmful substances in electronic and electrical products, so as to promote the environmental regeneration and final treatment of waste electronic and electrical equipment and ensure human health. The directive stipulates the limit requirements of toxic and harmful substances, and also requires countries to formulate corresponding punishment measures according to the Directive on Restricting the Use of Certain Hazardous Substances in Electronic and Electrical Equipment (2002/95/EC).

Eu RoHS1.0: in 2006, the eu issued the mandatory standard RoHS directive, which is mainly used to standardize the material and process standards of electronic and electrical products, aiming at eliminating six substances, namely lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers.

Eu RoHS 2.0: 20 15 in its official gazette, the eu issued directive (EU) 20 15/863, which revised annex ii of RoHS 2.0 (201165/eu) and officially put four kinds of phthalates.

RoHS promoted in China: According to AnnouncementNo. 2065438+23 of 2009 issued by the State Administration of Markets and the Ministry of Industry and Information Technology (hereinafter referred to as "Implementation Arrangement"), the products that are imported after 2011are included in the Implementation Arrangement.

ROHS detection and control scope: all products such as electronics, electrical appliances, medical care, communication, toys and security information. It includes not only the whole machine products, but also the parts, raw materials and packaging used in the whole machine production, which is related to the whole production chain.

RoHS detection principle: products are divided by materials, and harmful substances are detected by different materials. Generally speaking, metal materials need to detect four harmful metal elements such as cadmium, cadmium, lead, mercury, mercury and Cr6+ hexavalent chromium. In addition to these four harmful heavy metal elements, we should also test the brominated flame retardant (PBDE) of plastic materials.
