RoHS – Restriction of hazardous Substances


Due to the environmental concerns around the world, RoHS directive is implemented to thereby contributing to the protection of human health and the environment. The RoHS Directive, stands for “the restriction of the use of certain hazardous substances in electrical and electronic equipment.” This Directive will ban the placing on the EU market of new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants from 1st July 2006.



RoHS Limit: MCV

1. Lead (P)

<0.1% = <1,000 PPM

2. Mercury (Hg)

<0.1% = <1,000 PPM

3. Cadmium (Cr VI)

<0.01% = <1,000 PPM

4. Hexavalent Chromium (Cd)

<0.1% = <1,000 PPM

5. Polybrominated biphenyls (PBBs)

<0.1% = <1,000 PPM

6. Polybrominated diphenyls ethers (PBDEs)

<0.1% = <1,000 PPM


Manufacturers will need to understand the requirements of the RoHS Directive to ensure that their products, and their components, comply.



RoHS Compliance Sustem ISO 14001


As a component supplier, Hong Kong Watch Dial Factory Ltd. must take responsibility for the content of its products under the RoHS Directive. We enter the route of RoHS Compliance following the system – based approach.


We’ve developed a large and sophisticated database by sub-assemblies and components. This effort is made to enable control and identification RoHS complaint material throughout the supply chain. This system also facilities upload information and compliance reports on these materials. In addition, a quality management compliance system is also in force for compliance approvals and risk assessment controls.


We understand there’s the growing concern on the environmental quality issues. Therefore, HK WATCH DIAL has also obtained the ISO 14001 in order to take the duties of an environmental management. For the future, we can foresee more requirements and standards will come into place. As we have already received environmental requirements other than RoHS from our customers. We’re confident with the new systems and open for discussions for standards and requirements issues.
