What is ROHS certification? ROHS certification, which stands for "Directive Restricting the Use of Certain Hazardous Substances in Electronic and Electrical Equipment", is a mandatory environmental regulation formulated by the European Union (EU). The main purpose of this directive is to restrict the use of specific hazardous substances in electrical and electronic equipment in order to reduce the impact of these substances on the environment and human health.
The application process for EU ROHS certification is roughly as follows:
1. Determine product scope and applicable standards: First, companies need to clarify whether their products fall within the scope of application of the ROHS directive, and determine the applicable specific standards and restrictions.
2. Product testing: Choose a qualified laboratory to test products for harmful substances. Common detection methods include X-ray fluorescence spectrometry (XRF) for preliminary screening, and chemical analysis methods such as inductively coupled plasma mass spectrometry (ICP-MS), gas chromatography-mass spectrometry (GC-MS), etc. for accurate determination.
3. Preparation of technical documents: including detailed description of the product, design drawings, circuit diagrams, raw material list, production process flow, hazardous substance analysis report, etc.
4. Declaration of conformity: The company prepares a statement of compliance based on test results and technical documents to indicate that the product meets the requirements of ROHS certification.
5. Certification application: Submit a certification application to the certification agency, including product information, test reports, technical documents and compliance statements, etc.
6. Certification audit: The certification body will review the application materials and may conduct on-site audits to verify the company's production process and quality management system.
7. Certificate issuance: After passing the audit, the certification body issues a ROHS certification.
Hazardous substances targeted by EU ROHS testing include:
1. Lead (Pb): shall not exceed 0.1% (1000ppm).
2. Mercury (Hg): shall not exceed 0.1% (1000ppm).
3. Cadmium (Cd): shall not exceed 0.01% (100ppm).
4. Hexavalent chromium (Cr6+): shall not exceed 0.1% (1000ppm).
5. Polybrominated biphenyls (PBB): shall not exceed 1000ppm.
6. Polybrominated diphenyl ethers (PBDE): shall not exceed 1000ppm.
7. Di(2-ethylhexyl) phthalate (DEHP): shall not exceed 1000ppm.
8. Dibutyl phthalate (DBP): shall not exceed 1000ppm.
9. Butyl benzyl phthalate (BBP): shall not exceed 1000ppm.
10. Diisobutyl phthalate (DIBP): shall not exceed 1000ppm.
