Scope of standard 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 1 104 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:1.3.1 Test Method A-- Pressure Decay Leak Test for Nonporous Flexible Packages Without Restraining Plates1.3.2 Test Method B-- Pressure Decay Leak Test for Nonporous Flexible Packages With Restraining Plates1.4 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 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 and health practices and determine the applicability of regulatory limitations prior to use.
