Packaging - Flexible aluminium tubes - Test method to check the resistance of the internal protective coating against ammonia

The ammonia test is a quick test to check the chemical resistance of the internal protective coating of aluminium tubes. The test is used for flexible aluminium tubes for ammonia containing fillings and as an introductory test for newly developed internal protective coatings.

Overview

EN 15653:2009 (CEN) specifies a quick, practical test method (ammonia test) to check the chemical resistance of the internal protective coating of flexible aluminium tubes against ammonia. Approved by CEN in 2009, this method is intended for tubes used with ammonia-containing fillings and as an introductory screening test for newly developed internal coatings.

Key topics and technical requirements

• Test solution: aqueous ammonia with a mass fraction of 20–25%.
• Test equipment / safety: ventilated hood, test tube holder/rack, scissors and protective glasses.
• Test procedure (summary):
  • Stand tube samples on their caps and fill with the ammonia solution under a ventilated hood.
  • Place open tubes in a rack and immediately cover the open ends.
  • Store for 2 hours at room temperature.
  • Empty and rinse samples, then carefully cut open for inspection.
• Evaluation criteria:
  • The internal protective coating must not show large blisters or softening (checked by a scratch test).
  • Occasional blisters up to 5 mm diameter and detachment at cut edges are acceptable.
• Test report contents: the standard requires recording items including reference to EN 15653, batch and tube identification, sample description and dimensions, coating type, ammonia concentration, test results and defect counts, number of samples, acceptance/rejection decision (if applicable), factors affecting results, and date/place/tester identity.

Applications and who uses it

• Flexible aluminium tube manufacturers and converters use EN 15653:2009 for routine quality control of internal coatings intended for ammonia-containing products.
• Coating developers and R&D teams use the test as an introductory screen for new internal protective formulations.
• Quality assurance laboratories apply this quick method before more extensive chemical resistance testing.
• Brand owners and packaging specifiers reference the test when specifying coating performance for products that may contact ammonia or ammonia derivatives.

Practical value and limitations

• Provides a fast, reproducible screen for coating resistance to ammonia - useful for production checks and early-stage formulation evaluation.
• Not a comprehensive ageing or long‑term chemical resistance test; follow-up or more rigorous tests may be needed for full qualification.

Related standards and references

• EN 15653:2009 was developed by CEN/TC 261 (Packaging) and based on ETMA recommendations. For complete conformity and national implementation, consult your national standards body or the CEN Management Centre. For broader coating and packaging compliance, consider additional CEN packaging and coating test standards as applicable.
