A complete guide to the China RoHS testing process (GB/T 39560 standard) for landline phones, compiled based on the latest policies and testing requirements:
I. Core Testing Standards and Limit Requirements
1. Testing Standards
- Based on the GB/T 39560 series of standards (equivalent to the IEC 62321 international standard), covering testing for six hazardous substances.
- Limits:
- Cadmium (Cd) ≤ 0.01% (100 ppm)
- Lead (Pb), Mercury (Hg), Hexavalent Chromium (Cr⁶⁺), Polybrominated Biphenyls (PBB), Polybrominated Diphenyl Ethers (PBDE) ≤ 0.1% (1000 ppm).
2. Applicable Products
- Landline phones fall under the "telephone terminals" category (including fixed and cordless phones) in the "Catalogue for the Administration of the Restriction of Hazardous Substances in Electrical and Electronic Products" and must pass the China RoHS conformity assessment.
II. Application Process (5-Step Detailed Explanation)
Step 1: Material Preparation
- Required Documents:
- Product Specifications, Circuit Diagram, and Bill of Materials (BOM) (listing all homogeneous materials);
- Copy of Business License;
- Completed RoHS Testing Application Form.
- Sample Requirements:
- Provide samples of homogeneous materials, both complete and disassembled (metallic and non-metallic components must be separated, approximately 50–100g).
Step 2: Select a Testing Agency and Send Samples
- Select a laboratory with CNAS/CMA accreditation (such as Dezewei Testing);
- Sign a contract and mail samples, specifying the test items (e.g., only four heavy metals for metal parts, six for non-metallic parts).
Step 3: Laboratory Testing Process
1. Disassembly and Screening:
- Disassemble into the smallest homogeneous unit and use an XRF spectrometer for preliminary screening of heavy metals and bromine.
2. Confirmatory Testing:
- Exceeding standards will be sent for chemical analysis (e.g., GC-MS for brominated flame retardants, colorimetric analysis for hexavalent chromium).
3. Turnaround Time: Approximately 5–7 business days (excluding rectification time).
Step 4: Report Review and Rectification (if necessary)
- If the test fails:
- Replace the offending materials (e.g., lead solder, hexavalent chromium plating) and resubmit for testing.
- Upon passing the test, issue a GB/T 26125 test report confirming the accuracy of the product model and company information.
Step 5: Compliance Marking and Market Access
- Affix a green "e" mark to the product or packaging and disclose a table of hazardous substance content.
- Complete a self-declaration filing (not mandatory certification, but technical documentation must be retained for future reference).
III. Key Considerations
1. Cost Reference:
- Pricing depends on the number of materials and color complexity; the test costs approximately ¥500–¥2000.
2. Exemptions:
- Military, aerospace, and export-specific equipment are exempt. Civilian landline telephones are not exempt.
3. International Differences:
- EU RoHS 2.0 adds four new o-phenyl esters (with a limit of 0.1%). Exports to the EU require additional testing.
