    Significance and Use

    The vacuum, bubble test method, as described in Test Method D3078, and various other leak detection methods described elsewhere (Test Method D4991, Guide E432, Guide E479, Test Method E493, Test Method E498, Test Method E499, and Test Method E1603) have been successfully used widely in various industries and applications to determine that a given package is or is not a leaker. The sensitivity of any selected leak test method has to be considered to determine its applicability to a specific situation.

    The procedures presented in this test method allow the user to carry out package and seal integrity testing with sufficient sensitivity to quantify seals in the previously defined moderate to very fine seal ranges.

    By employing seal-isolating leak testing fixtures, packages constructed of various materials can be tested in the full range of seal performance requirements. Design of these fixtures is beyond the scope of this method.

    These seal/package integrity test procedures can be utilized as:

    A design tool,

    For tooling qualification,

    Process setup,

    Process validation tool,

    Quality assurance monitoring, or

    Research and development.

    1. Scope

    1.1 This test method includes several procedures that can be used for the measurement of overall package and seal barrier performance of a variety of package types and package forms, as well as seal/closure types. The basic elements of this method include:
