4. Summary of Test Method

4.1 Test Method A (Burst Test)Packages are tested in an apparatus that internally pressurizes the package until the package fails. The pneumatic supply and pressurization equipment need the capability to maintain an increasing pressure until the package bursts.The test measure is the maximum pressure detected before the package fails.

4.2 Test Method B,(Creep Test)Packages are tested in apparatus that internally pressurizes the package to a specified pressure and maintains that internal package pressure for a specific time. The test measure is pass/fail.

4.3 Test Method B, (Creep to Failure)-Packages are creep-tested and held until the package fails. Test setup is similar to that of the Creep Test except the pressure setting will need to be higher to ensure the package fails in a reasonable amount of time (that is, about 15 s). The test measure is the time until failure.
