Tear

What is a tear test?

Simply stated, tear resistance is the measurement of the ability of a specimen to resist tearing. Tear resistance can be considerably affected by the speed of the test, much like ripping a piece of paper, and the results commonly used when materials such as paper and rubber are tested.

Tear is a property also found in extensive use by the textile industry where tear strength is defined as the tensile force required to rupture a pre-slit woven fabric specimen.  Tear resistance testing can be found in plastic film, paper and textile industries; tear resistance in textiles involves the load required to propagate a single "rip-tongue" type of tear (tear coming from a cut); and edge tearing strength of paper is the load required to tear a sample over a V-notch fixture.
