Edit this paragraph 5, the progress of the current RoHS?
Some large companies have begun to take note RoHS and response measures, such as SONY's digital camera has been declared on the packaging: This product is lead-free soldering; lead-free ink. Ministry of Information Industry in 2004 also introduced the "Electronic Information Product Pollution Control Regulations" similar content and RoHS, and set up in October, "Electronic Information Products Pollution Control Standards Working Group" to study in line with China's national conditions and the establishment of electronic information products control standards; carry out pollution control and electronic information products and related research and revision of standards, in particular, urgently needed to accelerate development of industrial materials, processes, terminology, test methods and test methods and other basic standards.
Edit this paragraph 6, RoHS on the electronics industry of China
China Electrical Equipment Industry Association, according to the latest data, the first quarter of 2004, China's export of electromechanical products in China's export share of 55%. The EU has become China's export of electromechanical products in the major markets. As Chinese manufacturers and technological level of environmental concepts behind, RoHS directive makes the nearly 27 billion U.S. dollars of Chinese machinery and electronic products face EU environmental barriers. Give the Chinese government has been closely and look for a solution, the State Council instructed the Ministry of Information Industry is responsible for special EU environmental directives for research and response. Ministry of Information Industry, under the "Cleaner Production Promotion Law" and "Solid Waste Pollution Prevention Law" and other relevant laws and regulations to develop the "Electronic Information Products Pollution Control Measures for the Administration" has been completed, and in January 1, 2005 shall come into force. "Electronic Information Products Pollution Control Management Measures", from July 1, 2006, the inclusion of Electronic Information Products Pollution Prevention and Control of electronic information products in the directory shall not contain lead, mercury, cadmium, hexavalent chromium, brominated polymer diphenyl ether and polymerization of brominated biphenyls and other toxic and harmful substances. For the July 1, 2006 some time ago, the Chinese government requires manufacturers of electronic information products are toxic and harmful substances in the implementation of the production reduction measures, and actively looking for alternatives. At the same time, called "Electronic Information Products Pollution Control Standards Working Group," the authorities have already begun preparations for the establishment of the agency's main task is to study and establish consistent with China's electronic information product pollution control standards, conduct and Electronic Information Products Pollution Control research and development of relevant standards, in particular speed up the development of urgently needed materials, processes, test methods and experimental approach is based on standards. Price and non-RoHS RoHS prices (according to the official statement) general difference of 15% ~ 30%, but generally have according to their own products for processing.
Edit this paragraph 7.RoHS certification cycle
RoHS certification cycle: seven working days RoHS testing standards against harmful substances and methods (test method currently used is the industry's default method is not mandatory under the European Union)

Edit the significance of the implementation of this paragraph 9.ROHS
RoHS directive made sense with the WEEE directive in promoting environmental protection and energy conservation. WEEE is "directive waste electrical and electronic products" (Waste Electrical and Electronic Equipment) abbreviation. The directive by the European Parliament and the Council, the European Union Member States 13 August 2005 began to enforce. Its main purpose is to prevent the generation of waste, followed by waste to facilitate recycling, reuse, remanufacturing, reduce the waste of resources. Instruction covers almost all of the following 10 categories of electrical and electronic equipment. The directive aims to make manufacturers supplier afford their own recovery and recycling of electrical and electronic equipment, financial responsibility. Manufacturers, brands (including retailers selling its own brand products), importers and exporters must comply with the EU on the electrical and electronic equipment, these new requirements. From August 13, 2005 from EU countries and the extension of the WEEE directive 2003/108/EC promulgated for implementation. For the 10 new EU accession countries, extend the time limit as follows: 12 months: Slovenia (2004/312/EC); 24 months: the Czech Republic, Estonia, Hungary, Latvia, Lithuania and Slovakia (2004 / 312/EC); Cyprus, Malta and Poland (2004 * 486/EC)
