REACH certification is the abbreviation of the EU Regulation, Evaluation, Authorization and Restriction of Chemicals, \"Registration, Evaluation, Authorization and Restriction of Chemicals\", and is a chemical regulatory system implemented on June 1, 2007. The REACH Directive requires that all chemicals imported and produced in Europe must go through a comprehensive set of procedures such as registration, evaluation, authorization and restriction, in order to better and more simply identify the composition of the chemical to achieve the purpose of ensuring environmental and human safety.
The USB fan is a miniature electric fan used in the USB interface of a desktop computer or a notebook computer. The new type of brushless DC motor fan is quieter, more power-efficient, and has a longer lifespan than traditional motor fans. The following is a related introduction on the handling of RoHS testing for small fans.
REACH is the abbreviation of the EU regulation \"Registration concerning the Registration, Evaluation, Authorization and Restriction of Chemicals\" (REGULATION concerning the Registration, Evaluation, Authorization and Restriction of Chemicals). It was established by the EU and implemented on June 1, 2007. Regulatory system. This is a regulatory proposal concerning the safety of chemical production, trade, and use. The regulation aims to protect human health and environmental safety, maintain and improve the competitiveness of the EU chemical industry, and develop innovative capabilities for non-toxic and harmless compounds to prevent market fragmentation , Increase transparency in the use of chemicals, promote non-animal experiments, and pursue sustainable social development.
The circuit board is mainly composed of pads, vias, mounting holes, wires, components, connectors, filling, electrical boundaries, etc. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. The circuit board can be called a printed circuit board or a printed circuit board. The export of circuit boards to the EU requires environmental ROHS testing.
RoHS certification is also called environmental certification, which is in line with European and American standards. It is the abbreviation of \"The restriction of the use of certain hazardous substances in electrical and electronic equipment\" (The restriction of the use of certain hazardous substances in electrical and electronic equipment). It stipulates that if lead, Pb, Imports of harmful heavy metals such as cadmium Cd, mercury Hg, hexavalent chromium Cr6+, polybrominated diphenyl ethers PBDE and polybrominated biphenyls PBB have been banned by the EU from July 1, 2006.
With the widespread use of lithium batteries in mobile communications, electronic appliances and other fields, safety accidents caused by lithium battery explosions are not uncommon in recent years. You can often see in the news that lithium batteries explode or lithium batteries explode during battery charging while mobile phones are being charged. Safety accidents caused by fires, etc., so the battery performance test through the standard system is a way to solve whether the battery is safe and reliable.
