European standards specify the technical document requirements of the "Restriction of Hazardous Substances Directive 2"
European standards stipulate the technical document requirements of the "Restriction of Hazardous Substances Directive 2". On November 23, 2012, the European Union's "Official Journal" published the reference materials and name of the European Union's harmonized standard EN 50581. Manufacturers must comply with this new standard if they want to prove that their products comply with the revised Directive 2011/65/EU on the restriction of the use of hazardous substances in electrical and electronic equipment (RoHS2). The new standard has been approved by the European Committee for Electrotechnical Standardization (CENELEC). It stipulates that EU countries must implement unified standards before July 16, 2013, and EU standards that conflict with EN 50581 must be withdrawn before July 16, 2015. RoHS2 imposes restrictions on homogeneous material standards for six hazardous substances contained in electrical and electronic equipment placed on the EU market, and is exempted in only a few cases. Homogeneous materials refer to materials that cannot be mechanically separated into different substances through mechanical decomposition processes such as unscrewing, shearing, crushing, grinding and grinding. Therefore, all parts of electrical and electronic equipment must comply with the maximum content limits of hazardous substances within RoHS2. This maximum content limit is the same as the maximum content limit set out in the original Restriction of Hazardous Substances Directive. RoHS2 Annex II specifies restricted substances and their maximum content limits. The new standard requires manufacturers of end products to demonstrate compliance with applicable substance restrictions. However, the new standard recognizes that it is unrealistic to require manufacturers to conduct their own testing of all homogeneous materials in final assembled products.
