ASTM F2054 PDF

The seal is around a flexible package that is internally pressurized and enclosed with restraining plates. This burst test will increase pressure of the package until the seal bursts. The restraining plates serve to stabilize the product and ensure that pressure is distributed evenly. Uniform pressure distribution will help to identify the weakest point in the seal.

Full Description 1. Test Methods F describes methods of burst testing that do not include the use of restraining plates and are suitable to determine a packages general ability to withstand pressurization stresses. Under Test Methods F the stresses are not distributed uniformly to all areas of the package seal.

Under unrestrained conditions the stress on the package is highest at the middle of the pouch where it inflates to the packages maximum diameter; therefore, Test Methods F may not reliably detect the weakest area of the seal.

By placing the package within restraining plates during pressurization, the dimensional stability of the package is maintained in a manner that results in stresses applied more uniformly along the perimeter of the package, where seals are normally placed.

In particular it is intended as applicable to packages with seals that have a peelable seal feature peeled open by end user to remove contents of package. See Appendix X4 for information.

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. Particular caution is advised where users of this procedure may be required to design and fabricate restraining plate fixtures.

Reference Appendix X3 for further information regarding calculation of stress factors and structural design considerations.
