Eucert providing a complete solution for RoHS certification. The RoHS directive aims to restrict certain dangerous substances commonly used in electronic and electronic equipment. Any RoHS compliant component is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component.
Directive 2011/65/EU was published in 2011 by the EU, which is known as RoHS-Recast. RoHS includes a CE-marking directive, with RoHS compliance now being required for CE marking of products. RoHS also added Categories 8 and 9, and has additional compliance recordkeeping requirements.
Any business that sells applicable electrical or electronic products, equipment, sub-assemblies, cables, components, or spare parts directly to RoHS countries, or sells to resellers, distributors or integrators that in turn sell products to these countries, is impacted if they utilize any of the restricted 10 substances.
RoHS specifies maximum levels for the following 6 restricted substances. The following six applied to the RoHS .
Lead (Pb): < 1000 ppm
Mercury (Hg): < 100 ppm
Cadmium (Cd): < 100 ppm
Hexavalent Chromium: (Cr VI) < 1000 ppm
Polybrominated Biphenyls (PBB): < 1000 ppm
Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
RoHS Steps to Certification
The following steps are involved for RoHS certification.
Documentation Review: Review Bill of Materials, assembly drawings, Materials Declarations for each component and product, test reports and Conformance Certificates.
Audit: Inspect all manufacturing processes needed to meet RoHS compliance for the six restricted substances.
Testing: On-site testing is done to determine values of the six restricted RoHS substances.
Certification: After successful audit, a RoHS certificate is issued.
