The DGCCRF certification and testing process required for baking molds exported to France is organized in combination with French regulatory requirements and the characteristics of silicone products. The process is explained in detail step by step as follows:
I. Preliminary preparation stage
1. Submission of materials and information
- Product information: Provide mold name, model, material (such as food-grade silicone), production process, formula (including vulcanizer type, additives, etc.).
- Instructions for use: Specify the type of food contact (grease/acid/alcohol), operating temperature (such as -40℃~230℃), and contact time (long-term/short-term).
- Sample preparation:
- Provide 3 batches of finished products, with 5 to 10 unused clean samples per batch;
- Composite molds with metal supports need to provide silicone parts and metal substrate samples separately.
2. Select a certification body
- A laboratory approved by DGCCRF must be selected (such as [Shenzhen Dezewei Technology Testing]).
2. Core test items
Based on the characteristics of silicone, the test focuses on chemical safety and physical stability:
Test items Test standards
Full migration test EN 1186
Peroxide value test DGCCRF 2004-64
Volatile organic matter (VOM) HS-GC method
Heavy metal dissolution French Décret 92-631
Sensory test NF D25-001
> Note: Coated molds (such as non-stick silicone) need to test the coating and substrate separately.
3. Key points of production control (avoiding the core of failure)
1. Raw material control
- Choose medical grade gas phase silicone to avoid filler contamination in industrial glue;
- The preferred vulcanizing agent is double 25 type (the residual amount is lower than double 24 type).
2. Vulcanization process optimization
- Primary vulcanization: 120℃~160℃ molding (2~5 minutes);
- Secondary vulcanization (critical): 180℃~200℃ for 4~6 hours, forced ventilation to remove volatiles.
3. Production environment
- Clean workshop to prevent dust pollution, molds must be made of stainless steel to avoid heavy metal migration.
IV. Certification process and cycle
1. Laboratory testing (3~5 working days)
- Migration test (40℃×10 days or 100℃×2 hours accelerated experiment) → VOM thermogravimetric analysis → heavy metal ICP-MS detection.
2. Report review (1 working day)
- DGCCRF reviews the data, and if it fails, it needs to be rectified and retested.
3. Issuance of certification
- After meeting the requirements, obtain DGCCRF's declaration of conformity, which is valid for 3 years.
5. Common failure cases and solutions
- Problem: VOM exceeds the standard (inadequate secondary vulcanization) → Solution: Extend the vulcanization time to 6 hours, and calibrate the temperature to ±2°C.
- Problem: Odor in sensory test (vulcanizing agent residue) → Solution: Replace low-volatile vulcanizing agent and increase ventilation intensity.
- Problem: Nickel migration of metal support parts → Solution: Use 304 stainless steel (chromium ≥ 13%) as the base material.
