Restriction of Hazardous Substances
RoHS stands for Restriction of Hazardous Substances. RoHS, also known as Directive 2002/95/EC, originated in the European Union and restricts the use of specific hazardous materials found in electrical and electronic products (known as EEE). All applicable products in the EU market after July 1, 2006 must pass RoHS compliance.
The substances banned under RoHS are lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four different phthalates (DEHP, BBP, BBP, DIBP).
Producers who comply with these principles and wish to create a competitive advantage for themselves by applying to a certification body RoHS Certificate demand. Having this certificate of course adds a lot of value to the manufacturers. For example,
- They prove their value to human health.
- It proves that they are sensitive to the environment and that they produce in accordance with
- environmental conditions.
- It proves that they make production to make recycling of such product wastes possible.
- It has proven that the dangerous elements listed minimize the interaction during the use of the
- As a company, it increases its market reputation and image.
- It has achieved a significant competitive advantage both at home and abroad.
- Testing: Either on-site or XRF testing and/or lab phthalate solvent extraction testing is done to determine values of the ten restricted RoHS substances.
- Process Audit: Inspect all applicable manufacturing processes used towards RoHS compliance on-site.
- Documentation Review: Review the Bill of Materials, Technical File, assembly drawings, materials declarations, test reports, and conformance/compliance certificates from all suppliers.
The Technical File must contain the following:
– General product description and design structure information
– Risk assessment of materials, parts and subassemblies
– Conformity information on materials, parts, and subassemblies
– Manufacturing documentation and records
– Harmonized standards, specifications, and conformity procedures
- Certification Statement: After a successful audit, a RoHS Certificate of Compliance (also known as a Certificate of Conformity or Declaration of Conformity) is issued.
