Definition And Aim Of The Rohs Directive Although RoHS compliance and training seems to be a success story in the EU, in China it is still news and going strong. The first phase of China RoHS compliance a phase which involves mark and disclosure processes for products was implemented in February 2007. Chinas Ministry of Information Industry is defining RoHS compliance in that country and may head the RoHS compliance testing. So far,Ray Ban Outlet, the Ministry of Information Industry has not mentioned any exemptions for RoHS compliance,Cheap Ray Bans, which means that medical and military equipment may also be tested and forced to comply with RoHS definitions.Any RoHS compliant component is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and or the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance due to some issues in military grades.The sheer size of the Chinese tech market may also make compliance testing and enforcement challenging. So far, it is unknown how RoHS compliance will work in China, although some have voiced concern about the lack of RoHS training and the lack of warning tech companies have had about new regulations. Products and components which fail to meet RoHS compliance regulations will carry a different logo and are required to clearly list all the hazardous substances in the product. Each product not meeting RoHS compliance definitions also needs to list its Environmental Protection Use Period (EPUP),Ray Ban Sunglasses Outlet, or the number of years that the hazardous substances will not leak or cause any damage or injury (under normal use of the product).It looks as though China will define RoHS compliance differently than the EU. China requires all components and products that meet RoHS compliance regulations to carry a logo a green e in a circle.
