【国外标准】 Standard Test Methods for Internal Pressurization Failure Resistance of Unrestrained Packages

5.1 These test methods provide a rapid means of evaluating tendencies for package failure when the package is exposed to a pressure differential. Pressure differentials may occur during processes such as sterilization and transportation.5.2 These test methods are frequently used to quickly evaluate packages during the manufacturing process and at various stages of the package's life cycle.5.3 If correlations between pieces of test equipment are to be made, it is important that all parameters of the test method be exactly the same. Typical parameters may include, but are not limited to, package size, material, seal configuration, test equipment, rate of air flow into the package, sensitivity (machine response to pressure drop), and position of test article (see Fig. 1).FIG. 1 Open Package Test Positions5.4 These test methods do not necessarily provide correlation with actual package seal strength as typically measured using Test Method F88 (or equivalent).1.1 These test methods explain the procedure for determining the ability of packages to withstand internal pressurization.1.2 The burst test increasingly pressurizes the package until the package fails.1.3 The creep test maintains a specified pressure for a specified time or until the package fails.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 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.
