Micom laboratories is delighted to announce that it now offers the ASTM F1140 standard as part of its package testing and of its medical package testing services. This method details two tests procedures which rely on the use of a pressurization equipment to evaluate the ability of packages to withstand inner pressurization. However, this test protocol does not convey any correlation regarding the package seal strength. Hence, another standard must be used to characterize this property. Lastly, by associating this method with an accelerated aging test, it is possible to define the evolution of this attribute.
ASTM F1140 test
The goal of ASTM F1140 is to characterize the ability of a package to endure internal pressurization through the use of a burst test or of a creep test. More specifically, those two tests depict the response of the specimen towards a pressure differential. On the one hand, a burst test consists of steadily increasing the inner pressure of the sample until it fails. This test procedure allows to ascertain the peak pressure that the specimen can withstand before a breakdown occurs. On the other hand, a creep test consists of maintaining a specific internal pressure inside the specimen for a given time frame or until the latter fails. This test procedure assesses the ability of the specimen to retain its integrity for a particular time length at a given pressure. Lastly, if the package seal strength is a point a concern, the use of the ASTM F88 method is prescribed.
Micom offers polymer testing services for a wide selection of material and products. For more information about the ASTM F1140 test, we invite you to contact our material testing laboratory today. It will be our pleasure to answer your questions about either of those tests.
