The RoHS Directive is a mandatory standard established by EU legislation and is the "Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment". The list of documents and key process instructions required for EU RoHS testing and certification of audio equipment is compiled based on the latest regulatory requirements and practical experience:
I. Core Required Documents
1. Basic Product Information
- Complete product manual (including technical specifications and usage scenarios)
- Product appearance, internal structure, and exploded view
- Model list of the entire device (if differences are within a product series, please indicate them)
2. Material Composition Documents
- Key Documents: A detailed Bill of Materials (BOM) must include all component names, material types, weights, and supplier information.
- Material Safety Data Sheets (MSDS) for each component, especially for high-risk materials such as plastic housings, cables, and solder.
3. Circuit Design Documents
- PCB Layout
- List of key components (such as power modules, Bluetooth chips, and speaker drivers), with model and supplier information.
4. Supply Chain Compliance Proof
- RoHS test reports provided by suppliers (for purchased components such as batteries, capacitors, and connectors)
- Declaration of Conformity (DoC) for key components (such as lithium batteries)
5. Labeling Documents
- Product Label Design (Must include CE Marking and RoHS Compliance Marking)
- Packaging Warning Draft (English Version, Must include Hazardous Substance Control Statement)
II. Supporting Materials Required by the Testing Agency
| Project | Specific Requirements
| Test Samples | Provide 2-3 finished products (including a full set of accessories), must be mass-produced models
| Disassembly Instructions | Provide instructions for separating easily removable components such as batteries and circuit boards
| Exemption Application | If exemption clauses are required (e.g., lead in high-temperature solder), submit documentation supporting the exemption
III. Certification Process and Cycle
A [Document Preliminary Review] --> B [Sample Disassembly and Material Classification]
B --> C [Laboratory Chemical Testing]
C --> D [Limit Compliance?] }}
D -->|Yes|E[Issue RoHS Test Report]
D -->|No|F[Correct and Retest]
E -->G[Issue CE-RoHS Certificate]
- Turnaround: Normally 5-7 business days (up to 15 days for complex products)
- Fees:
- Basic testing fee: ¥1500-3000 (based on the number of materials, e.g., metal/plastic/coating separately)
- Additional fees: Expedited service (+30%), multi-model consolidated report (+¥800/model)
IV. Special Considerations for Audio Equipment
1. Wireless Functionality
- Bluetooth/Wi-Fi modules require a separate RoHS report for the RF section.
- Antenna coatings require testing for hexavalent chromium (limit ≤ 1000 ppm).
2. Key Testing of High-Risk Components
- Speaker ferrite (cadmium risk)
- PCB solder joints (lead content testing)
- Cable Jacket (Phthalate Plasticizer)
3. Common Failure Points
- Exceeding the DEHP limit in PVC wire (limit 0.1%)
- Lead content in solder > 1000 ppm
- Missing supplier's declaration of compliance
> Laboratory Selection Tips: Prefer institutions with CNAS/CMA accreditation (such as Dezewei Testing) to avoid reports being rejected by EU customs.
> The latest exemption list can be found in: European Commission Decision (EU) 2023/2030 (Exemption for lead in high-temperature solder until 2027).
