ROSH Certification

1, What is RoHS?
RoHS is "electrical and electronic equipment in the Restriction of Hazardous Substances Directive" (the Restriction of the use of certain hazardous substances in electrical and electronic equipment) abbreviation.
rohs certification also known as environmental certification is in line with European and American standards.
2, which refers to harmful substances?
A total of six hazardous substances listed in RoHS, including: lead Pb, cadmium Cd, Hg Hg, hexavalent chromium, Cr6 +, PBDE PBDE, PBB PBB.
RoHS directive restricting the use of the following six types of hazardous substances
A mercury (Hg) using the substance for example: temperature control, sensors, switches and relays, bulbs
2 examples of use of the substance of lead: solder, glass, PVC stabilizer
3 Examples of use of the substance of cadmium: switches, springs, connectors, casing and PCB, contacts, battery
4 chromium (VI) examples of the use of the material: metal with corrosion coating
5 Polybrominated biphenyls (PBB) example of the use of the material: flame retardants, PCB, connectors, plastic shell
6 Polybrominated diphenyl ethers (PBDE) example of the use of the material: flame retardants, PCB, connectors, plastic shell
3, why introduce RoHS?
First noted that electrical and electronic equipment containing heavy metals harmful to human health in 2000, a group of Dutch cable market of game found in cadmium. In fact, the electrical and electronic products are currently widely used in the production of solder, packaging printing inks contain harmful heavy metals such as lead.
4, when the implementation of RoHS?
The EU will in the July 1, 2006 implementation of RoHS, when the use of or containing 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.
5, RoHS specifically related to those products?
RoHS for all production processes and raw materials may contain six hazardous substances in the electrical and electronic products, including: white appliances, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, black appliances, such as audio, video products , DVD, CD, TV receivers, IT products, digital products, communication products; power tools, electric and electronic toys, medical electrical equipment
6, 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.
7, RoHS Electronics Industry in 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, carry out and Electronic Information Products Pollution Prevention 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.
8.RoHS certification cycle
RoHS certification cycle: seven working days RoHS banned hazardous substance testing standards and methods (currently used test is the default way the industry is not mandatory under the European Union)
9. Test Method
1, heavy metals - cadmium
RoHS limit is: 100PPM
Test Standards: EN1122
Method:
a, the samples will be cut into small pieces beaker, add concentrated sulfuric acid, heating to the sample is completely dissolved,
b, the board removed the beaker from the heating, cooling, and then adding hydrogen peroxide
c, repeat step b, the reaction solution is no longer bubbling and clarification, to remove the beaker from the heating plate and cooling
d, the solution to the filtrate to support quantitative ionized water, and then the yard by inductively coupled plasma emission spectrometer detection.
2, heavy metals - lead
RoHS limit is: 1000PPM
Test Standard: US EPA3050B
Method:
a, will be joined HN03 heated sample into the beaker
b, cool at room temperature, add H202 and then heated until the reaction is complete
c, repeat steps b
d, cooled at room temperature, then add HCI and heated
e, the cooling fluid to be deionized water, filtered and quantitatively, then the original plasma inductively coupled plasma emission spectrometer detection.
3, heavy metals - mercury
RoHS limit is: 1000PPM
Test Standard: US EPA3052
Method:
a, the cut pieces into the microwave sample digestion flask, add and nitric acid and hydrofluoric acid
b, digestion bottle into the microwave until completely dissolved by microwave digester reaction
c, the solution to the filtrate with deionized water, quantitatively. Then inductively coupled plasma atomic emission spectrometry detection
4, heavy metal - chromium
RoHS limit is: 1000PPM
Test Standard: US EPA3060A & 7196A
5, brominated flame retardants
RoHS limit is: 1000PPM
Test Standard: US EPA3540C
10.ROHS significance of the implementation of
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.
11.ROHS implementation of the national
RoHS EU Member States involved are Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Spain, Sweden, United Kingdom, Slovenia, Cyprus, Malta, Poland, the Czech Republic, Estonia, Hungary , Latvia, Lithuania, Slovakia, Iceland, Norway, Liechtenstein
12.ROHS certification testing sample preparation
Product manufacturer for inspection before the inspection ahead of the best split itself the product, packaging, and were marked on each package the product name and number, in principle, the weight of each component required for the test: Solid 10 -20 g liquid 10-20 mg.
