1. What is ROHS certification mark?

ROHS certification is the directive on restricting the use of certain hazardous substances in electrical and electronic equipment. It stipulates that if electrical and electronic products contain harmful heavy metals such as lead, cadmium, mercury, hexavalent chromium, polybrominated diphenyl ethers and polybrominated biphenyls, the EU will ban the import on July 1, 2006.

2. ROHS certification

On January 27, 2003, the European Parliament and the European Council adopted Directive 2002 / 95 / EC, that is, the directive on restricting the use of some hazardous substances in electronic and electrical equipment, referred to as RoHS directive. The basic content is: from July 1, 2006, the use of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers will be restricted in newly listed electronic and electrical equipment products.

After the RoHS directive was issued, it has become a formal law within the EU since February 13, 2003; Before August 13, 2004, EU Member States will be transformed into their own laws / regulations; On February 13, 2005, the European Commission re examined the scope of the directive and formulated additional items in the list of prohibited substances taking into account the development of new technologies. After July 1, 2006, the EU market will officially prohibit the sale of products with excessive content of six substances.

RoHS mark

(1) Hazardous substances refer to.

RoHS lists six hazardous substances, including lead Pb, cadmium Cd, mercury Hg, hexavalent chromium Cr6 +, polybrominated diphenyl ether PBDE and polybrominated biphenyl PBB.

(2) Why launch RoHS?

It was noted for the first time that electrical and electronic equipment contained heavy metals harmful to human health, which was cadmium found in a batch of game console cables sold on the market in the Netherlands in 2000. In fact, at present, the solder and ink printed on packaging boxes widely used in the production of electrical and electronic products contain harmful heavy metals such as lead.

(3) When to implement RoHS.

RoHS will be implemented on July 1, 2006. At that time, electronic products using or containing heavy metals, PBDE, PBB and other flame retardants will not be allowed to enter the EU market.

(4) What products are involved in RoHS?

For all electronic products that may contain the above six hazardous substances in the production process and raw materials, EU ROHS mainly includes:

White household appliances, such as refrigerator, washing machine, microwave oven, air conditioner, vacuum cleaner, water heater, etc.; black household appliances, such as audio, video, DVD, CD, TV receiver, it, digital, communication, etc; Electric tools, electronic toys, medical appliances, etc.

3. Identification precautions for ROHS certification:

1. The sign shall be clearly visible and not easy to fade or remove;

2. When marking on the product, it shall generally be marked at the obvious position of the product, such as the front of the product, the side and back of the function key;

3. Other suitable eye-catching colors can also be used, in which the molding can be the same as the product color.

4. If the product cannot be marked due to the limitations of product volume, shape, surface material or function, the marking carrier can also be paper manual, manual CD or packaging.
