The GB6675 standard applies to all toys, meaning all products or materials designed or intended for use by children under the age of 14. Regarding "mechanical and physical properties," Chinese and EU toy standards are largely similar. The process and key points for obtaining a China GB6675 certification report for children's jewelry, compiled from historical conversations and the latest search results, ensure compliance with national mandatory standards:
I. Confirming the Testing Scope and Standard Applicability
1. Product Definition
- Children's jewelry refers to decorative items such as necklaces, bracelets, earrings, and hair accessories intended for children under the age of 14. Regardless of the material (metal, plastic, textile, etc.), all must comply with the GB6675 standard.
- Special Exclusions: Pure gold or silver jewelry (without added components) may be exempt, but jewelry containing alloys, coatings, or plastic components must be tested.
2. Core Testing Standards
| Testing Section | Corresponding Items
| Mechanical and Physical Properties | Risk of Small Parts Falling Off, Sharp Edges, Cord Length
| Migration of Specific Elements | Leachable Heavy Metals (Lead, Cadmium, Mercury, Chromium, etc.)
| Flammability | Burning Rate of Textile or Hair Accessories
| Plasticizer Limits | Phthalates (DEHP/DBP, etc.) Content
II. Selecting a Testing Agency and Submitting Samples
1. Agency Qualification Requirements
- The laboratory must possess CMA (China Metrology Accreditation) and CNAS (China National Accreditation Service) certification, such as Dezewei Testing.
- Preference is given to agencies with experience in children's product testing (qualification number required).
2. Sample Preparation Specifications
- Provide three complete sets of samples (including packaging and labels), covering all material types (e.g., metal chains, plastic beads, coated parts).
- Indicate the usage scenario (e.g., whether it will come into contact with the mouth) to determine migration testing conditions.
III. Testing Process and Core Items
1. Laboratory Testing Phase
- Mechanical and Physical Testing:
- Tensile Testing (to check whether small parts are prone to detachment and to prevent swallowing risks);
- Sharp Edge/Point Inspection (to simulate child skin contact).
- Chemical Safety Testing:
- Heavy Metal Migration (Lead ≤ 90 mg/kg, Cadmium ≤ 75 mg/kg);
- Total Phthalates ≤ 0.1%.
- Additional Items:
- Burning Rate Test for Textile Components (Flame Spread ≤ 30 mm/s).
2. Special Requirements
- Metal accessories require additional nickel release testing (≤ 0.5 μg/cm²/week).
IV. Report Generation and Certification
1. Report Content Requirements
- Must include: test method (e.g., ICP-OES), instrument model, and comparison of measured data with the limit.
- Attach the laboratory's CMA/CNAS accreditation seal and interline stamp.
2. Compliance Labeling
- Products must include an age warning (e.g., "Not suitable for children under 3"), material description, and the applicable standard number (GB6675).
V. Cycle, Cost, and Notes
| Item | Description
| Cycle | Routine testing: 5-7 working days, including migration testing, which can be extended to 10-15 days
| Cost | Basic testing: ¥1,000-2,500; metal/multi-material jewelry: ¥2,500+ (due to increased project volume)
| Validity | Typically 1 year; e-commerce platforms (e.g., Tmall and JD.com) require annual renewal.
| High-Risk Items | Spot checks focus on small parts detachment, excessive lead in coatings, and excessive phthalates.
Key Recommendations
Pre-test Optimization: Conduct heavy metal screening on coatings and welds before production to reduce rectification costs.
