Types of Tests

Puncture (Burst, Sharpness)

What is a Puncture test?

Simply stated, a puncture test determines the resistance of film to the penetration of a probe at a single constant test speed and tries to emulate what happens in the end use applications of the film.  Puncture strength tests are used to determine the puncture or rupture characteristics of a material and is typically a compressive type test where the specimen compressed by a probe until it ruptures, or until a defined travel limit is reached.

Puncture testing is commonly used to determine the strength of film, rubber or membrane, but is also by food processors to determine the ripeness of a product. Puncture testing may be used in medical applications for determining the sharpness of a hypodermic syringe or a scalpel blade etc.
