    Stainless steel products for RoHS certification test items

    Author:中認聯(lián)科 time:2020-08-15 Ctr:1112

    Stainless steel (Stainless Steel) is the abbreviation of stainless and acid-resistant steel. It is called stainless steel that is resistant to weak corrosive media such as air, steam, and water, or is stainless steel; and chemically resistant to chemical corrosion media (acid, alkali, salt, etc.) Corrosion steel is called acid-resistant steel. Stainless steel products are relatively common in our lives, and ROHS testing is required for such products to be sold in the EU. If the product is not certified for RoHS, it will cause an incalculable loss to the exporter, and may cause no one to care about your product; but if it enters the market and is found to have not done relevant testing, it will also cause significant losses to the company!

    The scope of products covered by the ROHS directive is very wide, covering all electronics, electrical, toys, electrical appliances, communications, medical, security information and other products. The ROHS directive not only applies to the complete machine product, but also applies to the parts, fasteners, original materials and packaging used in the production of the complete machine. ROHS touches the entire production chain and even the industrial chain. RoHS testing is to test whether lead Pb, cadmium Cd, chromium Cr, mercury Hg, polybrominated biphenyls PBBs, and polybrominated diphenyl ethers PBDEs in electronic and electrical products or raw materials of electronic and electrical products exceed the limit requirements of EU RoHS2.0. The test is simple and the cost is not high.
