The RoHS testing process for home printers is indeed a crucial step in product compliance, and a clear process guide can help you complete certification efficiently. As electronic and electrical equipment, home printers require a China RoHS test report obtained according to the prescribed procedures.
I. Complete Process for Obtaining a China RoHS Testing Report (Applicable to Home Printers)
Step 1: Document Preparation
- Core Documents
- Completed RoHS Testing Application Form (must include product name, model, manufacturer information, etc.)
- Provide Product BOM (Bill of Materials), specifying the materials and suppliers of each component
- Product manual, circuit diagram, structural cross-sectional view (for easy disassembly and testing in the laboratory)
- RoHS testing reports for key components (e.g., power adapter, PCB board, etc., to reduce redundant testing)
- Sample Requirements
- 1-2 complete unit samples (must be functional for functional verification)
- If the product structure is complex, samples of disassembled components can be provided (e.g., plastic casing, metal bracket, electronic components, etc.)
Step 2: Cooperation with Testing Institutions
- Selecting a Laboratory
Must possess CNAS (China National Accreditation Service for Conformity Assessment) and CMA (China Metrology Accreditation) qualifications, for example, Dezeway Testing CNAS registration number: L8083
- Cost Assessment
Pricing is based on the complexity of the product materials:
- Single material (e.g., pure metal parts): Approximately 500-1000 RMB/item
- Complex products (multi-material combinations): Costs increase with the number of materials used; home printers typically range from 2000-5000 RMB.
Step 3: Laboratory Testing Stage
- Testing Items
According to the Chinese standard GB/T 26125-2011, six hazardous substances are tested:
| Substance | Limit
| Lead (Pb) | ≤0.1%
| Mercury (Hg) | ≤0.1%
| Cadmium (Cd) | ≤0.01%
| Hexavalent Chromium (Cr⁶⁺) | ≤0.1%
| Polybrominated Biphenyls (PBBs) | ≤0.1%
| Polybrominated Diphenyl Ethers (PBDEs) | ≤0.1%
II. Testing Process
1. Sample Breakdown: Classified by material (metal, plastic, electronic components, etc.)
2. Initial Screening Test: Rapid screening using X-ray fluorescence spectrometry (XRF)
3. Precise Detection: For materials suspected of exceeding standards, quantitative analysis is performed using ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) or GC-MS (Gas Chromatography-Mass Spectrometry)
Step 4: Report Issuance and Rectification
- Cycle: Routine testing 5-7 working days (expedited service can be shortened to 3 working days)
- Result Processing
- Pass: A RoHS test report is issued, typically valid for 1-2 years (if the product material remains unchanged)
- Fail: Rectification of the non-compliant components is required (e.g., replacing with environmentally friendly raw materials), and resubmission for testing until passing.
Step 5: Compliance Labeling and Archiving
- Mark "Restricted Use of Hazardous Substances" on the product nameplate or instruction manual (refer to SJ/T 11364-2014 standard)
- Retain test reports and related technical documents for at least 5 years in case of random inspections by market supervision departments.
III. Precautions for Testing Home Printers
- Key components to focus on: printhead, motherboard, power module, plastic casing (prone to containing cadmium, lead, etc.)
- Cost optimization techniques: Prioritize purchasing components that have passed RoHS certification, which can significantly reduce the overall testing cost.
- Regulatory updates: China RoHS 2.0 (Regulations on the Restriction of Hazardous Substances in Electrical and Electronic Products) has been implemented; ensure that testing items are synchronized with the latest standards.
