Description of content:
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
