The following are the core processes and precautions for California 65 testing of electronic devices, integrated from relevant regulations and testing agency requirements:
I. Preliminary preparation
1. Confirm the scope of testing
- All accessible parts (such as shells, buttons, interfaces and other parts that directly contact the human body) need to be tested for chemical substances.
- Exemption conditions: If non-removable parts (such as packaged chips) meet RoHS standards, partial exemptions can be applied.
2. Prepare materials
- Technical documents: product manual, material list (BOM table), production process description.
- Test samples: Usually 2-3 sets of complete samples are required, focusing on testing accessible parts.
II. Core testing process
1. Select a certified laboratory
- Prioritize laboratories with CNAS/CMA qualifications and officially recognized by California.
2. Test items and limits
Total lead (Pb), ≤100ppm (non-coated materials), housing, circuit board, solder joints, etc.
Total cadmium (Cd), ≤300ppm (special parts such as batteries), batteries, plastic housings
Phthalates, single type ≤0.1% (1000ppm), cables, soft plastic parts
Bisphenol A (BPA), ≤1000ppm, polycarbonate parts (such as display screens)
Flame retardants, TDCPP≤25ppm, etc., plastic housings, insulating materials
3. Test methods
- Determination of heavy metals using ICP-MS and atomic absorption spectrometry.
- Detection of phthalates by gas chromatography-mass spectrometry (GC-MS).
III. Reporting and Compliance
1. Testing Cycle
- Routine testing: 5-7 working days
- Expedited service: can be shortened to 3 days
2. Certification Mark
- If the test exceeds the standard, a warning (such as "contains lead") must be marked on the product or packaging, and the format must comply with California 65 requirements.
3. Subsequent Maintenance
- The report is valid for 2 years, but the material list must be updated and reviewed every year.
- Re-testing is required when the product process or material changes.
