Standard RoHS testing procedures and key points for electronic boards exported to the EU:
I. Preliminary Preparation
1. Confirm product scope
- Electronic boards fall under the category of electrical and electronic equipment (EEA) specifically regulated by the RoHS Directive (2011/65/EU).
- Applicable voltage range: AC ≤ 1000V, DC ≤ 1500V.
2. Technical Documentation Preparation
- Required materials: Circuit schematic, product manual, BOM (including all component material information).
- Sample Requirements:
- Provide 2-3 complete electronic board samples;
- Separation by material: Metal components (e.g., solder joints, housing) must be separated from non-metallic components (e.g., substrates, plastic parts);
- Sample weight requirements: 5-10g for metal materials, 10-30g for plastic/coating materials (depending on the test item).
2. Testing Implementation Process
1. Selecting a certification body
- A third-party laboratory with ISO 17025 certification (such as Dezewei Testing) must be selected.
2. Submission and test items
- Test items and limits [[6]()][[10]()]:
| Hazardous substances | Limit (ppm)
| Cadmium (Cd) | ≤100
| Lead, mercury, hexavalent chromium, etc. | ≤1000
| 4 phthalates | ≤1000
- Test methods:
- Metal parts: XRF scanning (rapid screening);
- Non-metal parts: GC-MS/HPLC (precise chemical analysis).
3. Laboratory testing cycle
- The routine process takes 3-5 working days, and complex samples may be extended to 7 days.
III. Certification and Compliance Stage
1. Report and Certificate
- After passing the test, obtain a RoHS test report containing sample data and compliance conclusions.
- Apply for a RoHS Certificate of Compliance (optional, but helpful for market acceptance).
2. Technical Documentation and CE Marking
- Prepare technical documentation (including test reports, design drawings, and Declaration of Conformity).
- Affix the CE mark to the product (mandatory under RoHS 2.0).
3. Ongoing Compliance Management
- Retesting is required when materials/processes change.
- Annual supply chain audits are recommended to ensure raw material compliance.
IV. Common Issues and Costs
- Cost Reference:
Basic testing fee is approximately ¥1,000-2,000 (based on the number of materials).
- Frequent Failure Points:
- Hexavalent chromium (plating process);
- Phthalates (plastic cables/connectors).
