ASTM F1140/F1140M-13 (2020) e1 standard test methods are used to evaluate the failure resistance of Encasement under internal pressurized conditions. These test methods are suitable for rapid assessment of the failure tendency of Encasement when it is exposed to differential pressure, especially during sterilization and transportation. Methods include blasting tests with gradual pressurization until Encasement fails, and creeping tests with specified pressure maintained for a period of time. The standard specifies that the test equipment, Encasement parameters and test conditions should be consistent to ensure the accuracy of test results. The user needs to use the standard separately according to the unit of the system used, and establish appropriate safety and health measures before use.
