Pressure resistance test procedures for products bottled with aluminium screw caps
Scope of application
This data sheet provides test methods that enable evaluating the level of sealing obtained with an aluminium screw cap applied on a filled glass bottle.
Different tests are proposed covering the various objectives for such a test, either for product development, for routine checks during filling operations or troubleshooting, etc.
These are:
Different tests are proposed covering the various objectives for such a test, either for product development, for routine checks during filling operations or troubleshooting, etc.
These are:
- Climatic simulation test (§ 3)
- Bubble point test (§ 4)
- Secure seal test (§ 5). This test applies to both aluminium screw caps and crown caps. For crown caps, refer to Chapter 6.3 in GUIDE NO. 4 - 26 mm CROWN CAPPING

This joint group aims to coordinate the production of documentation at the junction of glass container production and closure application. It accompanies the development of documentation for glass containers for different types of closures including, but not limited to, aluminum screw caps, crown caps, and their components (liners). This joint group also provides an opportunity for cap and liners manufacturers to open discussions on specific work items of the permanent glass groups
