According to German LFGB regulations, coffee machine filters, as materials intended for direct food contact, must undergo LFGB certification before entering the German and EU markets. The following is the detailed testing process and key considerations:
I. Core Certification Process
1. Confirming Testing Standards and Items
- Material Type: Select the corresponding testing standard based on the filter material (e.g., metal, nylon, silicone, PP plastic, etc.).
- Core Testing Items:
- Chemical Migration Test: Dissolution of heavy metals (lead, cadmium), plasticizers (phthalates), formaldehyde, etc.
- Sensory Test: Evaluates whether the filter produces odor or flavor transfer after being immersed in high-temperature water.
- Specific Material Tests:
- *Nylon Filter*: Caprolactam Migration (applicable to CPSIA standards).
- *Metal Filter*: Chromium and Nickel Dissolution (16 CFR Part 175.300).
2. Select a CPSC-accredited laboratory
- The laboratory must be ISO/IEC 17025 accredited and CPSC authorized (e.g., ID 1552).
- Provide the laboratory name, address, and contact information for certificate preparation.
3. Submit samples and materials
- Sample requirements:
- Provide 3-5 complete filter samples (including packaging).
- Mark the material composition ratio (e.g., nylon content ≥ 80%).
- Technical documents: Product specifications, material declaration, and production process description.
4. Laboratory Testing Phase
| Test Content | Simulation Conditions
| Chemical Migration Test | Immersion in 3% Acetic Acid Solution and 10% Ethanol Solution
| Sensory Evaluation | Odor/Taste Evaluation after High-Temperature Water Immersion
| Thermal Stability Test | 100°C High-Temperature Cycling (for plastics)
5. Obtain Report and Certificate
- Test Report: The laboratory will issue a detailed data report (approximately 5-7 business days).
- CPC Certificate Drafting: The manufacturer or importer drafts the certificate based on the report and must include:
- Product model and production batch
- Laboratory information and test standards
- Declaration of Conformity ("Complies with LFGB §30-31").
II. Special Requirements for Filters
1. High Temperature Resistance: Must pass a 100°C water cycle test to ensure no deformation or chemical release.
2. Structural Integrity: Must not break or fall off after repeated use (e.g., metal filters require salt spray rust testing).
3. Labeling: The product or packaging must be labeled with the cutlery logo and material code (e.g., PP > 5).
III. Common Causes of Failure
1. Excessive Heavy Metal Content: Chromium leaching from stainless steel filters > 0.1 mg/dm² (limits refer to BfR recommendations).
2. Sensory Disqualification: Silicone filters release odor at high temperatures.
3. Incomplete Certificate Information: Missing the laboratory ID or production address (must be accurate to the city).
IV. Fees and Time
- Basic Fee: Starting from ¥800 (single-material filter);
- Expedited Service: 3 business days (fee increases by 30%-50%)
