：【question】 Visits：
The RoHS Directive is a mandatory standard established by EU legislation, namely the "Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment." The complete process and key points for obtaining an EU RoHS test report for power adapters are summarized in conjunction with EU directive requirements and testing agency practices:
I. Core Process
A [Confirm product suitability] --> B [Select a certification body]
B --> C [Prepare samples and documents]
C --> D [Laboratory testing]
D --> E {{Is it compliant?}}
E --> |Yes | F [Obtain RoHS report]
E --> |No | G [Retest after material rectification]
F --> H [Apply the CE mark for entry into the EU market]
II. Step-by-Step Guide
1. Confirm testing requirements
- Applicability: Power adapters fall under the "Information Technology and Communications Equipment" category, which is subject to mandatory control under the RoHS Directive.
- Testing Items:
✅ Heavy Metals: Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent Chromium (Cr⁶⁺)
✅ Flame Retardants: Polybrominated Biphenyls (PBBs), Polybrominated Diphenyl Ethers (PBDEs)
✅ Plasticizers: DEHP/BBP/DBP/DIBP (Phthalates)
- Limit Requirement: ≤ 0.1% (≤ 0.01%) for each hazardous substance in homogeneous material (Cadmium).
2. Selecting a Testing Agency
- Qualification Requirements: Laboratories with CNAS/CMA accreditation are preferred (e.g., Dezewei CNAS Registration Number: L8083).
- Cost Reference:
- Single Material/Single Color: Approximately 500-800 RMB
- Multi-Material/Complex Structure: 1,000-2,000 RMB (charged by the number of components).
- Turnaround Time: Standard 5-7 business days (expedited processing can be shortened to 3 days).
3. Sample and Document Preparation
| Material Type | Requirements
| Test Samples | Provide 2-3 complete adapters, representing a mass production batch
| Technical Documents | Include: Schematic, Product Manual, Bill of Materials (BOM) (with component material information)
| Separation Requirements | Metal components (housing/solder joints) and non-metal components (plastic/coating) must be submitted for testing separately.
4. Laboratory Testing Methods
- Initial Screening: XRF scanning for rapid detection of heavy metals.
- Precision Analysis: Chemical dissolution method for detection of phthalates and hexavalent chromium.
- Special Treatment: Focus on testing high-risk materials such as solder, plastic housings, and insulating coatings.
5. Report Obtaining and Using the Report
- Report Content: Includes product model, test standard, limit comparison, and compliance conclusion.
- Validity Period: Default: 1 year (retesting is required if materials/process changes are made).
- Market Access:
- The report must be used in conjunction with CE certification (RoHS 2.0 falls under the CE Directive).
- E-commerce platforms (such as Amazon) require the report to indicate the brand name and the qualifications of the testing agency.
III. Key Considerations
1. Material Risk Management:
- Avoid using lead-containing solder, cadmium-based stabilizers, or DEHP-plasticized PVC.
2. Standard Update Alert:
- The EU plans to add restrictions on medium-chain chlorinated paraffins (MCCPs) in 2025; please monitor this in advance.
3. Document Retention:
- Technical documentation (including test reports and declarations of conformity) must be retained for 10 years.
IV. FAQs
▸ Q: Which components of the power adapter require key testing?
- High-risk components: PCB (including solder), plastic casing, power cord insulation, and internal connectors.
▸ Q: What should I do if my report is questioned by EU customs?
- Supplementary test data and laboratory qualification documents are required.
