RoHS

Introduction to RoHS Directive

With effect from July 1, 2006 RoHS (Restriction of Hazardous Substances) Directive (2002/95/EC) restricting the use of lead in electrical and electronic products and other hazardous substances. The aim is to limit the six kinds of substances in electrical and electronic products, in order to protect the safety and health of humans and the environment. For many businesses, this is a big challenge to the environment.

WEEE regulations to a minimum, Member States can be coupled with strict recycling standards, while the RoHS express those substances must be restricted and its limits.

Although RoHS is a European Union directive, the EEE producers located outside the EU if the final product sales to the EU Member States must also comply with RoHS requirements. The definitions and interpretations of the instructions there should be no differences within each country in the EU, RoHS verified its products will be the economic body unimpeded access.

RoHS directive control products project:

       
Large household products

       
Small household products

       
IT and telecommunications equipment

       
Consumer products

       
Lighting

       
Electrical and electronic tools

       
Toys, leisure and sports equipment

       
Vending Machine

RoHS Directive on the the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, referred to as the control for the electrical and electronic products (Class 8 medical devices and 9 monitoring equipment), asking that the six kinds of specific chemical substances, including:

Lead: commonly used in plumbing, fuel additives, packaging objects, plastic and rubber objects, dyes, pigments, coatings, electronic components and so on.

Cadmium: commonly used for packaging objects, plastic and rubber objects, stabilizers, dyes, pigments, coatings, electronic components, surface treatment.

Cr (VI): commonly used in packaging objects, objects of plastic and rubber, dyes, pigments, coatings, plating, surface treatment.

Mercury: commonly used in batteries, packaging objects, thermometers, electronic components and so on.

Polybrominated biphenyls (PBBs): commonly used in printed circuit board electronic components, wire and flame retardant agents.

Six polybrominated diphenyl ether (PBDE): commonly used in printed circuit boards, electronic components, wire and flame retardant agents.

The basis of the amount of control of these six substances identified in the table below, the amount of control here is to focus on the concentration of homogeneous material (homogeneous material), the homogeneous material is defined as "not through mechanical separation and further decomposition of a single materials. "

Limit of six hazardous substances in the RoHS Directive: the maximum allowable content of the RoHS directive, lead (Pb), mercury (Hg), hexavalent chromium (Cr6 +), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) 0.1% (1000ppm), cadmium (cd) 0.01% (100ppm), the limits are statutory basis on which to develop product is RoHS compliant.


The sophistication and complexity of the electrical and electronic goods, from upstream to downstream (of raw materials to finished product) has been operating the circumstances are rare, so the brand manufacturers for raw materials, parts, OEM supplier contract (in the contract may require declaration of conformity assurance, inspection reports and other relevant documents, and damages and liability provisions) requires that each order suppliers to meet RoHS requirements, so that the final product is inadvertently related specifications. International manufacturers of this multi-lists green procurement standards, and sets out more stringent allowable concentration to ensure the conformity of the goods.
