RoHS Certification

1. What is RoHS?
RoHS is "electric and electronic equipment in the restrictions on the use of certain hazardous substances directive" (the Restriction of the use of certain hazardous substances in electrical and electronic equipment) of the initials.
2. Harmful substances is what »
RoHS listed a total of six hazardous substances, including: lead, Pb, Cd Cd, mercury Hg, hexavalent chromium Cr6 +, PBBs ether PBDE, PBB PBB.
3. Why should we launch RoHS?
The first took note of electrical and electronic equipment containing harmful to human health is of heavy metals in the Netherlands in 2000 a group of marketing the game of cadmium found in the cable. In fact, electric and electronic products in the production of the current large-scale use of solder, the package printing inks contain lead, harmful heavy metals.
4. When the implementation of RoHS?
The EU will be July 1, 2006 implementation of RoHS, will use or contain heavy metals and PBBs ether PBDE, PBB PBB, such as 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 harmful substances above the six electrical and electronic products, mainly including:
White appliances such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters,
And domestic electrical appliances, such as audio, video products, DVD, CD, TV receivers, IT products, digital products, communications products;
Electric tools,
Electrical electronic toys
Medical electrical equipment
6. RoHS current progress »
Some large companies have begun to take note that RoHS and response measures, such as SONY company's digital cameras have been in the box on the statement: This product is a lead-free welding, a lead-free printing ink.
Ministry of Information Industry in 2004 also introduced a "pollution prevention and control of electronic information products management approach" with the RoHS similar content, and in October the establishment of the "electronic information products pollution control standards working group" to study and establish the conditions of our country's electronic and information products pollution Control standard system for electronic and information products and pollution control standards relating to research and revision of the system, in particular the urgent need to accelerate the development of industrial materials, technology, terminology, test methods and test methods, and other basic standards.

CHB is to provide professional PFOS perfluorooctane sulfonate test
Perfluorooctane sulfonate (Perfluorooctane sulfonates-PFOS) in the form of anions in salt, and derivatives of polymer, because of their anti-oil and water as raw materials of which are widely used in textiles, carpets, paper, coatings, fire foam , Video materials, aviation hydraulic oil products.
2006/122/EC directive that the EU made of material on the market in perfluorooctane Sulfonyl compounds (PFOS) can not exceed the quality of the content of 0.005 percent, finished and semi-finished products and spare parts in the limit is 0.1 percent. This indicates that the EU official in a total ban on PFOS products in use.
2006/122/EC directive also pointed out that, PFOA and PFOS have similar risk, will also discuss ban
Electrical and electronic products, textiles, leather and some special coating materials need to pay attention to PFOA and PFOS, fluorine polymer materials such as PTFE generally contain PFOA.
● PFOA, PFOS testing methods: extraction, LC-MS, GC-MS testing.
