LFGB testing is applicable to all materials, including those manufactured using the latest technologies. Examples include testing the chrome plating on grills, the heat resistance of Teflon coatings on cooking pans, and testing the silicone seals in kettles. According to the German LFGB (Food and Household Commodities Act), food contact materials such as dinner plates must pass the following core testing items. The specific content and basis are as follows:
I. Basic Testing Items (Common to All Materials)
1. Sensory Testing (Odor and Taste Transfer)
- Evaluates whether the dinner plates release unusual odors or affect the taste of food when in contact with food.
2. Initial Material Inspection
- Conducts a preliminary analysis of the material composition and potential risks.
II. Specific Testing by Material
1. Plastic Dinner Plates (e.g., PP, melamine)
- Transferable Components Test: Detects the migration of chemical substances such as plasticizers and monomer residues.
- Heavy Metal Leaching Test: Detects the leachable amount of heavy metals such as lead, cadmium, and mercury (limits must comply with BfR standards).
- Overall Migration Level (OML): Tests the total migration of non-volatile substances in a simulated food environment (e.g., acid, oil, alcohol) (limit: ≤10 mg/dm²).
2. Metal Plates (e.g., stainless steel)
- Composition Analysis: Confirms that the material meets food-grade alloy requirements.
- Heavy Metal Release Test: Focuses on testing the migration of elements such as chromium, nickel, and manganese (according to EDQM standards).
3. Silicone Plates (e.g., potholders)
- Volatile Organic Compound (VOM) Test: Tests the release of organic compounds from silicone (limit: ≤0.5%).
- Peroxide Residue Test: Ensures the absence of harmful residues from processing.
4. Ceramic/Glass Plates
- Lead and Cadmium Release Test: Tests strictly in accordance with DIN 51032 (with stricter limits for the lip contact area).
III. Additional Testing for Special Coatings or Composite Materials
- Non-stick Coatings (e.g., Teflon):
- Formaldehyde, phenol, and primary aromatic amine (PAA) migration testing (limit: PAA must not be detected).
- Color Coatings/Printed Patterns:
- Azo Dye Testing (banned carcinogenic dyes).
IV. Testing Process and Cycle
1. Sample Submission: Provide a dinner plate sample and material description.
2. Project Evaluation: The laboratory will determine a specific testing plan based on the material.
3. Testing Cycle: Typically 5-7 working days.
4. Report and Certification: Upon passing the test, a LFGB Certificate of Conformity will be issued.
Notes
- Material Complexity: If a dinner plate contains multiple materials (e.g., a metal handle and a ceramic body), each component must be tested separately.
- Regulatory Updates: After 2023, restrictions on overall migration and specific chemicals (e.g., bisphenol A) will be tightened. It is recommended to monitor the latest BfR recommendations.
