Description

1.1 This draft Standard covers the determination of gross leaks in flexible packaging containing a headspace gas. Test sensitivity is limited to 1 × 10−5 atm cm3/s (1 × 10−6 Pa m3/s) or even less sensitive as indicated in a recent inter laboratory test (reported in Section 12).1.2 Small leaks may not be detected by this procedure. Viscoelastic effects on the products, or entrapped air, become significant and prevent passage through small openings. Positive pressure inside the pouch after the vacuum is drawn may force the product to plug small leaks. The size of the leak that can be detected is dependent upon the products contained, the nature of the packaging material, and the test parameters selected.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.Worth mentioning is that this draft standard is technically identical with  ASTM D3078 − 2021
