The maximum stress, usually found near the onset of tearing, is recorded as the tear resistance in newtons or pounds-force. In most cases, comparison between films of dissimilar thickness is not valid. The challenges of testing to this standard are: By continuing to use our site, you accept our cookie policy.

The shape of the specimen is designed to create a tear when the specimen is pulled in tension.

Work Asttm s – proposed revisions of this standard. The specimen geometry of this test method produces a stress concentration in a small area of the specimen. Need help or have a question?

It is often used for quality control checks or for material comparison where tear failures are possible. Therefore, it is advisable to refer to that material specification before using this test method. Non-repeatability of results — ASTM D requires the operator to exclude results that deviate markedly from the mean value.

Tear resistance measures the wstm force required to tear film or sheet.

Tear Resistance ASTM D

Preventing specimen slippage — When testing thin films, the specimens typically undergo thinning as they are stretched. This test method aims to measure force to initiate tear for plastic films that do no exhibit brittle failure or do not elongate greater than Hence, tearing forces measured in newtons or pounds-force cannot be normalized over a wide range of specimen thickness without producing misleading data as to the actual tearing resistance of the d100.

The specimen is die cut to the appropriate shape from a sheet. WaveMatrix 2 for Dynamic Testing. Next Checking to see if you are a returning visitor….
