Puncture strength testing is used to determine the puncture or rupture characteristics of a material. It is generally a compressive test where a material is compressed by a probe or other type of instrument until the material bursts or an elongation limit is achieved.
Puncture tests are commonly used to determine the strength of materials such as film, rubber or membranes. It is also often used in the food processing industry to determine the ripeness of a product. The puncture test can be used in medical applications to determine the sharpness of a syringe, scalpel or blade, or to measure the resistance and ductility of synthetic skin.
This test method determines the resistance of the film to the penetration of a probe at a constant test speed. Performed under standard conditions, the test provides a biaxial tension that is similar to the type of stress encountered in many product end user applications.
Tinius Olsen provides force measurement equipment and material testing machines for puncture testing. All testing hardware is fully complemented by our Horizon software.
