RoHS is a mandatory standard established by EU legislation. Its full name is "Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment." This standard, which officially came into effect on July 1, 2006, primarily regulates the materials and process standards of electrical and electronic products, making them more conducive to human health and environmental protection. The complete process and precautions for obtaining EU RoHS testing and certification for computer mice:
1. Clarifying Testing Items and Standards
According to the RoHS 2.0 Directive (2011/65/EU), mice must be tested for 10 hazardous substances:
1. Heavy Metals: Lead (Pb ≤ 0.1%), Cadmium (Cd ≤ 0.01%), Mercury (Hg ≤ 0.1%), Hexavalent Chromium (Cr⁶⁺ ≤ 0.1%).
2. Flame Retardants: Polybrominated Biphenyls (PBBs) and Polybrominated Diphenyl Ethers (PBDEs) ≤ 0.1%.
3. Plasticizers (Phthalates): DEHP, BBP, DBP, and DIBP are all ≤ 0.1%.
> ⚠️ Special Requirements: Wireless mice must also comply with the CE-EMC Directive (Electromagnetic Compatibility).
II. Certification Process
Step 1: Prepare Materials and Samples
- Required Documents:
- Product Technical Documents (including Bill of Materials, Circuit Diagram, and User Manual);
- Sample Quantity: 3-5 pieces (must include all material types, such as plastic housing, metal roller, circuit board, etc.).
- Separation Requirements: Metal and non-metal components must be tested separately.
Step 2: Select a Testing Agency
- EU-accredited laboratories (such as ECHA-authorized laboratories) are preferred, providing one-stop services (testing + document review).
Step 3: Laboratory Testing and Evaluation
- Testing Methods:
- XRF spectrometer for rapid screening of heavy metals (preliminary testing recommended);
- Chemical testing in accordance with EN 62321:2012.
- Turnaround time: Regularly 5-7 business days, expedited to 3 days (30%-50% additional fee).
Step 4: Obtaining Certification Documents
- Upon passing certification, the following will be issued:
- RoHS test report (with product images and batch number);
- Declaration of Conformity (DoC) (signed by the company's responsible person).
III. Cost Reference
| Project | Fee Range | Description
| Basic Testing | ¥2,000-3,000 | Discount available for mixed metal testing
| Non-metallic Components | ¥2,500+ | Plastics, silicone, etc. are priced separately
| Complete Device Testing | ¥40,000+ | Including 500+ materials (e.g., main unit)
IV. Key Considerations
1. Dynamic Compliance:
- The RoHS list may be updated every six months.
2. High-Risk Components:
- PCB solder (lead risk) and electroplated buttons (hexavalent chromium risk) require special testing.
3. Consequences of Non-Compliance:
- Exceeding the cadmium/lead limit will result in a sales ban in the EU and a fine of up to €100,000.
V. Action Recommendations
1. Internal Pre-Inspection: Purchase XRF equipment to conduct in-house screening for heavy metals to reduce rework costs.
2. Supply Chain Management: Require suppliers to provide RoHS compliance certification for raw materials.
