Puncture resistance testing This test method determines the resistance of film to the penetration of a probe at a single constant test speed. Performed under standard conditions, the test imparts a biaxial stress that is similar to the type of stress encountered in many product end user applications.

Consequently, puncture testing methods are governed by standardized test procedures that specify the test set up including the rate, the specimen size, as well as the puncture probe geometry. This blog post will cover puncture testing, recommended equipment, and the test methods that outline test setups to test certain materials at the optimal test conditions.
Typical probes/fixtures used for puncture/penetration tests Penetration tests usually employ cylinders (2mm – 10mm diameter), cones, ball probes or needles. Small probes are particularly recommended for the assessment of rupture force or for the testing of multiple structure products e.g. measuring skin/crust/coatings and continuing to test the underlying material.
