Overview
EN 15766:2009 is a European standard developed by CEN that specifies a test method for determining the polymerization of the internal coating of flexible aluminium tubes using acetone. This standard is essential for manufacturers and quality control laboratories involved in packaging solutions that utilize aluminium tubes with internal epoxy-phenolic coatings. It ensures that the polymerization process of the tube's internal coating meets quality requirements, preventing product contamination or coating failure.
Key Topics
- Scope: The standard defines a procedure to assess the degree of polymerization of internal coatings in aluminium tubes by using acetone as a solvent agent.
- Principle: Epoxy-phenolic coatings, commonly applied inside aluminium tubes, dissolve in acetone before polymerization. Properly polymerized coatings resist dissolution, allowing quality verification by rubbing the coating with acetone-soaked cotton wool and observing any coloring or surface degradation.
- Test Materials:
- Acetone (CAS No. 67-64-1)
- Cotton wool
- Testing Procedure:
- Cut and flatten the aluminium tube section.
- Rub the coated surface 10 ± 1 times with acetone-soaked cotton wool applying ~10 N/cm² pressure.
- Evaluate any color transfer to the cotton wool and changes to the coated surface (mattness, stickiness).
- Result Evaluation: No discoloration on cotton wool and no adverse surface reaction confirms sufficient polymerization. Minor coloration is acceptable if no surface changes occur.
- Reporting: Complete test reports include standard references, batch information, test conditions, results, and tester details.
Applications
EN 15766:2009 serves a critical role in the packaging industry where flexible aluminium tubes are widely used for products such as:
- Pharmaceuticals
- Cosmetics
- Food products and condiments
- Industrial adhesives and pastes
By ensuring the internal coating of aluminium tubes is properly polymerized, the standard helps avoid contamination risks or chemical interactions between the tube material and its contents, maintaining product safety and integrity.
Related Standards
- EN 1230 series for aluminium tube packaging dimensions and mechanical properties
- ISO 1133 for polymer melt flow testing, relevant in coating polymer characterization
- CEN/TC 261 standards on packaging materials and testing methods
- Other regional or international regulations addressing packaging safety and quality control methods
Adherence to EN 15766:2009 supports manufacturers and quality assurance teams in delivering high-quality, safe, and reliable flexible aluminium tubes by verifying the crucial internal coating's polymerization status using a standardized, reproducible test method. This helps maintain consistent product performance and consumer protection across the packaging supply chain.
