Detailed process and key points of China GB4806 testing for coffee machines, integrating the latest standard requirements and practical guidelines:
I. Preparation stage before testing
1. Material splitting and list submission
- Provide a list of materials for each component of the coffee machine (such as stainless steel filter, plastic cup body, silicone seal ring, coated liner, etc.), and clarify the parts that come into contact with food.
- Supplier information and material certification (such as food-grade ABS plastic, 304 stainless steel certification) must be included.
2. Sample requirements
- Submit 3-5 sets of complete samples (including different colors/production batches) for testing;
- Special parts (such as heating element coating, sealant) need to be sampled separately.
II. Laboratory testing process
Phase 1: Sample pretreatment
- Classification and processing by material: plastic parts need to be subjected to dissolution test, metal parts need to be surface cleaned, and coatings need to be subjected to scratch test simulating actual use conditions.
Phase 2: Core test items
Test categories
Basic safety indicators: sensory requirements (no odor, fading), total migration (≤10mg/dm²), potassium permanganate consumption (≤10mg/kg)
Metal parts: migration of lead, cadmium, chromium, nickel, arsenic (such as stainless steel filter needs to measure hexavalent chromium ≤0.005mg/kg)
Plastic/silicone parts: phthalates (6 types), bisphenol A (≤0.6mg/kg), volatile organic compounds (TVOC)
Coating parts: perfluorinated compounds (PFAS), hexavalent chromium migration, wear resistance test
Phase 3: Special additional tests
- Electronic components: If it contains a heating module, additional heavy metal migration (such as lead content in circuit board plating) is required.
- Microbiological testing: Long-term water storage components (such as water tanks) need to measure the total number of colonies (≤100CFU/g).
III. Report generation and review
1. Cycle and cost
- Regular test cycle: 5-7 working days, cost about 1000-2000 yuan (basic package);
- Expedited service: report in 3 days (cost increased by 30%).
2. Report content
- Contains CMA/CNAS qualification identification, test methods, limit comparison and compliance conclusion.
IV. Key points of enterprise compliance
1. Label specification
- Need to mark "food contact" logo, applicable temperature range (such as high temperature resistance 120℃) and cleaning instructions.
2. Supply chain management
- Require raw material suppliers to provide GB4806 compliance declaration, and re-submit for inspection when batches are changed.
3. Subsequent maintenance
- Regular sampling (recommended once every 6 months), pay attention to standard updates (such as the addition of chloropropanol testing in 2025).
V. Recommendations for selecting a testing agency
- Give priority to laboratories with dual CMA/CNAS qualifications (such as Shenzhen Dezewei Testing);
- Confirm whether the laboratory has the ability to test the entire coffee machine (not single material testing).
> Note: If the coffee machine contains imported parts (such as German heating tubes), it must simultaneously comply with the standards of origin (such as EU EC1935/2004) and undergo additional testing.
