RoHS Directive and "WEEE Directive" provides for the inclusion of hazardous substances restrictions on the management and end-of-life recycling management of ten categories of 102 kinds of products, the first seven categories of products are China's main export electrical products. Including large household appliances, small household appliances, information and communication equipment, consumer products, lighting equipment, electrical and electronic tools, toys, leisure and sports equipment, medical equipment (except for implanted or infected products), monitoring and control instruments, vending machines. [edit]The RoHS Directive restricts the use of the following six hazardous substances 1. Lead (Pb) Examples of the use of this substance: solder, glass, PVC stabilizers
2. Mercury (Hg) (mercury) Examples of the use of this substance: thermostats, sensors, switches and relays, light bulbs
3. Cadmium (Cd) Examples of the use of this substance: switches, springs, connectors, Cadmium (Cd) Examples of use: switches, springs, connectors, housings and PCBs, contacts, batteries
4. Hexavalent chromium (Cr 6+) Examples of use: metal-attached corrosion coatings
5. Polybrominated biphenyls (PBB) Examples of use: flame retardant, PCBs, connectors, plastic housings
6. Polybrominated diphenyl ethers (PBDE) Examples of use: flame retardant, PCBs, connectors, plastic housings [Edit, Plastic enclosure [Edit] Test Principle: According to the EU WEEE& RoHS Directive requirements, AOV is to split the product according to the material, to different materials are tested for hazardous substances. Generally speaking:
6?1 metal materials need to test four kinds of harmful metal elements such as (Cd cadmium / Pb lead / Hg mercury / Cr6 + hexavalent chromium) 6?1 plastic materials in addition to checking the four kinds of harmful heavy metal elements need to be detected in addition to the detection of brominated flame retardants (polybrominated biphenyls PBB / polybrominated diphenyl ethers PBDE) 6.1 At the same time, the packaging material of the different materials need to be carried out separately. Packaging materials are also tested for heavy metals (94/62/EEC)The following are the upper limit concentrations of the six hazardous substances specified in RoHS:
Cadmium: less than 100ppm
ROHOS lead: less than 1000ppm
Steel alloys less than 3500ppm
Aluminum alloys less than 4000ppm
Less than 40,000ppm in copper alloys
Mercury: less than 1,000ppm
Hexavalent chromium: less than 1,000ppm [Edit] Reasons for the introduction of RoHS The first time that the presence of heavy metals harmful to human health in electrical and electronic equipment was noticed was the discovery of cadmium in cables of a batch of marketed game consoles in the Netherlands in 2000. In fact, electrical and electronic products in the production of a large number of current use of solder, packaging box printing ink contain lead and other harmful heavy metals. [Edit paragraph] When to implement RoHS The EU will implement RoHS on July 1, 2006, when the use or the presence of heavy metals and polybrominated diphenyl ethers PBDE, polybrominated biphenyls PBB and other flame retardants in electrical and electronic products will not be allowed to enter the EU market [Edit paragraph] RoHS specifically related to those products RoHS for the production of all production processes and raw materials may contain the above six kinds of Hazardous substances in all production processes and raw materials may contain the above six electrical and electronic products, including: white goods, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc.; black appliances, such as audio, video products, DVDs, CDs, TV receivers, IT products, digital products, communication products, etc.; power tools, electric toys, electrical and electronic medical and electrical equipment [Edit paragraph] Currently the RoHS progress A number of large companies have already paid attention to RoHS and started to take action to address the issue. Some big companies have already noticed RoHS and started to take measures to deal with it, such as SONY's digital camera has already declared on the box: this product adopts lead-free soldering; and adopts lead-free ink printing.
The Ministry of Information Industry (MII) also issued the Measures for the Administration of Pollution Prevention and Control of Electronic Information Products (EIPP) in 2004, which is similar to RoHS, and set up the "Working Group on Standards for the Prevention and Control of Pollution from Electronic Information Products" in October, to study and establish a standard system for the prevention and control of pollution from electronic information products in line with China's national conditions, and to carry out the work of developing standards related to the prevention of pollution from electronic information products. Pollution prevention and control of electronic information products related to the standard research and revision work, in particular, to speed up the development of the industry's urgent need for materials, processes, terminology, test methods and test methods and other basic standards. [Editorial] RoHS impact on China's electronics industry According to the latest data of China Electrical Appliance Industry Association, in the first quarter of 2004, China's exports of electromechanical products in China's exports accounted for 55%. And the European Union has become the main market for China's mechanical and electrical products exports. Due to the backwardness of Chinese manufacturers' environmental protection concepts and processes, the RoHS directive has made nearly 27 billion dollars of Chinese mechanical and electrical products face the EU's environmental barriers.
The Chinese government has been paying close attention and studying countermeasures, and the State Council has specially tasked the Ministry of Information Industry (MII) to be responsible for the research and response to the EU environmental protection directives. The Ministry of Information Industry has completed the Administrative Measures for the Prevention and Control of Pollution of Electronic Information Products, which was formulated in accordance with the Law on Promotion of Cleaner Production and the Law on Prevention and Control of Environmental Pollution by Solid Wastes and other relevant laws and regulations, and came into effect on January 1, 2005, and is expected to be implemented by the end of this year.
The Administrative Measures for the Prevention and Control of Pollution from Electronic Information Products stipulates that, since July 1, 2006, electronic information products listed in the catalog of key prevention and control of pollution from electronic information products shall not contain lead, mercury, cadmium, hexavalent chromium, polymerized brominated biphenyls (PBB) ethyl ether and polymerized brominated biphenyls (PBB) or any other toxic or hazardous substances. For the period prior to July 1, 2006, the Chinese government required manufacturers of electronic information products to implement measures to reduce the production of toxic and hazardous substances and actively seek alternatives.
At the same time, a working group on standards for the prevention and control of pollution from electronic information products has begun preparations for its establishment. The main task of the group is to study and establish standards for the prevention and control of pollution from electronic information products in line with China's national conditions, and to carry out research on and formulate standards for the prevention and control of pollution from electronic information products, in particular, to speed up the development of urgently needed materials, materials, and materials for the prevention and control of pollution. The main task of the organization is to research and establish standards for pollution prevention and control of electronic information products in line with China's national conditions, and to carry out research and formulation of standards related to pollution prevention and control of electronic information products, in particular, to accelerate the formulation of basic standards for materials, processes, testing methods and experimental methods that are urgently needed.
Overview of ROHS in China
Legal basis:
Ministry of Information Industry of the People's Republic of China (MIC), National Development and Reform Commission of the People's Republic of China (NDRC), Ministry of Commerce of the People's Republic of China (MOFCOM), General Administration of Customs of the People's Republic of China (GAC), State Administration for Industry and Commerce of the People's Republic of China (SAIC), General Administration of Quality Supervision, Inspection and Quarantine (GACQSIQ), General Administration of Quality Supervision, Inspection and Quarantine (GACQSQ), General Administration of Quality Supervision, Inspection and Quarantine (GAVQSIQ). General Administration of Supervision, Inspection and Quarantine of the People's Republic of China and the State Environmental Protection Administration of the People's Republic of China jointly signed the "Management Methods for Controlling Pollution by Electronic Information Products" (No. 39)
(Management Methods for Controlling Pollution by Electronic Information Products / Ministry of Information Industry Order # 39). Products / Ministry of Information Industry Order #39)
Scope of Application:
These methods shall be applied to control and reduce the pollution of the environment and other public hazards caused by electronic information products in the process of production, sale and import of electronic information products within the territory of the People's Republic of China*** and the People's Republic of China. However, the production of export products is excluded.
Summary content:
Electronic information products in the design, production and sales process should be in line with the national standards or industry standards for the control of toxic and hazardous substances or elements of electronic information products in two phases:
Phase I:
Environmental protection should be marked on the electronic information products on the market should be marked with the period of time for environmental protection, marking the toxic contained therein, Harmful substances or elements contained in the name, content, where the components and whether they can be recycled; electronic information products packaging, should be labeled with the name of the packaging material. Can be in accordance with the requirements of the standards SJ/T 11363-2006, SJ/T 11364-2006, SJ/T 11365-2006, GB 18455-2001.
The second stage:
To enter the key management directory (in the development) of the product must ensure that toxic and hazardous substances in the product has been replaced, or the content does not exceed the limit standards and through the mandatory product certification (CCC certification)
European Union RoHS system and the Chinese RoHS system in the specific implementation of the difference: the European Union practice is to first legislate to prohibit the electronic product Containing six hazardous substances, and then list a series of temporary exceeded the standard categories, and so on the future technical conditions are ripe in the move out of this catalog. China is the other way around: once the technical conditions for a product are ripe, it is put into the catalog, and the products in the catalog cannot exceed the standards. [edit]EU RoHS Directive added 6 exemptions On June 11, 2009, the EU OJ published 2009/443/EC, added 6 exemptions to the RoHS Directive, as follows:
