ASTM F2095-07R21 - Standard Test Methods for Pressure Decay Leak Test for Flexible Packages With and Without Restraining Plates

1.1 These test methods cover the measurement of leaks in nonporous film, foil, or laminate flexible pouches and foil-sealed trays, which may be empty or enclose solid product. If product is enclosed, seals or surfaces cannot be in contact with water, oils, or other liquid.

1.2 These test methods will detect leaks at a rate of 1 × 10⁻⁴ sccs (standard cubic centimetres per second) or greater, in flexible packages. The limitation of leak rate is dependent on package volume as tested.

1.3 The following test methods are included:

1.4 These test methods are destructive in that they require entry into the package to supply an internal pressure of gas, typically air or nitrogen, although other gases may be used. The entry connection into the flexible package must be leak-tight.

1.5 For porous packages, see 9.3.

1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.7 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.

1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
