A test report for glass food storage jars under EU 1935/2004 is indeed a crucial document for compliant export of products. Understanding the specific testing items and procedures can help you complete the certification efficiently. As food contact containers, glass food storage jars must pass two core tests: heavy metal leaching and migration.
I. Core Testing Items for Glass Food Storage Containers (EU Regulation 1935/2004)
1. Heavy Metal Leaching Test (Mandatory)
- Detected Elements and Limits
| Element | EU Limit (mg/L) | Testing Standard | Source of Risk
| Lead (Pb) | ≤0.01 | 84/500/EEC | Colored Glazes, Crystal Glass Formulations
| Cadmium (Cd) | ≤0.005 | 2005/31/EC | Cadmium Red/Cd Yellow
| Arsenic (As) | ≤0.002 | EN 1388-3:2008 | Decolorizing Agent As₂O₃
| Antimony (Sb) | ≤0.015 | ISO 17765:2008 | Clarifying Agent Sb₂O₃
- Test Conditions: 1. **Immersion in 4% acetic acid solution (simulating acidic food) at 24℃±2℃ for 24 hours (extend to 72 hours for canned goods), with ICP-MS used to determine the dissolution concentration (detection limit 0.1 ppb).
2. **Migration Tests:**
- **Overall Migration:** ≤10 mg/dm² (simulated solutions such as 4% acetic acid and 50% ethanol, EN 1186 series standards)
- **Specific Migration:** For organic contaminants (such as aromatic amines and formaldehyde) in colorants and coatings, tested according to EN 13130 series standards.
3. **Physical Properties and Safety Tests:**
- **Thermal Shock Resistance:** No cracking after a temperature difference ≥120℃ (ISO 7459:2021, simulating a refrigerator to microwave oven scenario).
- **Corrosion Resistance:** No cracking after immersion in 5% NaCl solution for 72 hours (EN 12875-1:2005, assessing detergent resistance).
- Sensory Testing: Immersion solution shows no odor or discoloration (EU 82/711/EEC, ensuring no impact on food flavor).
II. Complete Process for Obtaining Testing Reports (2025 Practical Version)
Step 1: Document and Sample Preparation
- Required Documents
- Product Manual (Specify material: soda-lime glass/borosilicate glass/crystal glass)
- Coloring component pigment composition table (supplier must provide a heavy metal content declaration)
- Production process flow chart (highlighting annealing and painting processes)
- Sample Requirements
- 3-5 complete finished products (including lids, sealing rings, and other accessories)
- If metal accessories are included (e.g., stainless steel buckles), a separate accessory testing report is required.
Step 2: Selection and Testing of Testing Institutions
- Institution Qualifications: Must possess CNAS (ISO/IEC 17025) certification (e.g., Dezewei Testing CNAS registration number: L8083)
- Testing Cycle: Standard 5-7 working days (including lead/cadmium leaching + total migration + physical properties), expedited 3-5 working days
- Fee Reference:
- Basic Package (Lead/Cadmium Leaching + Total Migration): 800-1,200
- Full Item Testing (including arsenic/antimony + thermal shock resistance + sensory evaluation): 1,500-2,200
Step 3: Report Issuance and Declaration of Compliance
- Core Report Content
- Test Sample Information (Model, Batch, Material Description)
- Test Conditions and Methods Standards (Simulated Solution Type, Immersion Time Must Be Specifyed)
- Comparison of Individual Test Results with Regulatory Limits (with Spectrum)
- Declaration of Conformity (DoC): Must include manufacturer information, product intended use, compliance with 1935/2004/EC and specific standards (such as EN 13885:2021 Glass Container Standard)
Step 4: Market Access and Regulatory Response
- Labeling Requirements: Products must be labeled "For Food Contact Use" (English: "Food") Contact Materials”
- Record Keeping: Test reports and pigment safety data sheets (SDS) must be kept for at least 10 years, as EU market regulators (such as the German BfR) may conduct random checks at any time.
