The nationally promoted RoHS certification is a requirement outlined in the "Catalogue of Electrical and Electronic Products Subject to Restriction of Hazardous Substances" issued in 2019 by the State Administration for Market Regulation and the Ministry of Industry and Information Technology.
Projector RoHS Testing Full Process Guide (2025 Latest Version)
I. Pre-Test Preparation (Core Steps)
Product Disassembly and Homogeneous Material Definition
Disassemble into the smallest homogeneous units according to GB/T 26572-2023 standard (e.g., plastic casing, circuit board, lens assembly, power adapter, etc.)
Focus on High-Risk Components:
LCD Screen (Contains Mercury Risk)
Power Board (PBDE Flame Retardant)
Solder Joints (Lead Content)
Plastic Casing (Phthyl Acrylate Plasticizers)
Technical Document List
| Required Materials | Specific Requirements
| Product BOM | Must indicate the material, supplier, and model of all components
| Photos of the Complete Unit and Components | Clearly show the structure and location of key components
| Supplier Compliance Declaration | Must include a commitment to limits for 10 substances including lead, mercury, and cadmium
| Production Process Flow | This section focuses on key processes such as welding and painting that may introduce hazardous substances.
II. Testing Implementation Process (5-Step Method)
**Laboratory Selection**
**Qualification Requirements:** Must possess CNAS accreditation (check the official website: China National Accreditation Service for Conformity Assessment)
**Recommended Standards:** GB/T 26125-2023 (Test Methods for Hazardous Substances), GB/T 39560-2025 (New Phthalate Testing)
**Sample Submission**
**Sample Quantity:** 1 complete unit + 2 each of key components (power board, motherboard, casing, etc.)
**Submission Requirements:** Model number and batch number must be clearly indicated, along with a disassembly description.
**Testing Items and Methods**
| Substance Category | Test Method Standard | Limit Requirements
| Lead (Pb) | ICP-MS (GB/T 26125-2023) | ≤0.1% (1000ppm)
| Cadmium (Cd) | ICP-OES (GB/T 26125-2023) | ≤0.01% (100ppm)
| Phthalate Esters | GC-MS (GB/T 39560-2025) | Total of four items ≤0.1%
Report Acquisition
Standard processing time: 5-7 working days (expedited to 3 days)
Report Validity: Must include CNAS stamp, testing engineer's signature, and a comparison table of measured data and limits.
Compliance Declaration and Labeling
Sign the "Declaration of Compliance on Restriction of Hazardous Substances" (DoC). The template can be downloaded from the Ministry of Industry and Information Technology website.
Affix a green e-label to the product (size ≥5mm×5mm), format as per SJ/T. Standard 11344-2021
III. Notes on New Regulations in 2025
New Control Requirements
Mandatory testing for four phthalates (DEHP, DBP, BBP, DIBP), with a total limit of 0.1%
Adjustment to Exemption Clause: Solder with lead content ≤85% requires a separate exemption certificate (valid for 3 years)
Solutions to Common Non-Compliance Items
Excessive Phthalate Content: Replace PVC material with TPU wire, increasing cost by approximately 2 RMB/meter.
Hexavalent Chromium Plating Layer Issues: Switched to a chromium-free passivation process, increasing the pass rate to 98%.
Power Board PBDE Exceeding Standards: Replaced with brominated epoxy resin flame retardant (supplier SDS report required).
IV. Cost and Timeline Reference
Testing Fee: Approximately 1000-2000 RMB for whole-machine testing (charged based on the number of disassembled materials).
Timeline Optimization: Confirm expedited processing with the laboratory in advance; timeline can be reduced to 3 working days.
Long-Term Compliance: Quarterly sampling and retesting of key components is recommended to ensure supply chain stability.
