This standard provides a method for testing the gas tightness of closures on flexible tubes used in packaging. It outlines procedures to assess the integrity of the seal under specific conditions, ensuring consistent evaluation methods. The test procedures are designed to simulate real-world scenarios that may affect the performance of the closure. The standard specifies the equipment, materials, and conditions required for conducting the tests. It also includes details on the preparation of samples and the interpretation of results. The methodology described is intended to ensure that the closures meet the necessary requirements for maintaining gas tightness during storage and transportation.
