Tear Strength - ASTM D624
The force required to tear a specified test specimen divided by the specimen thickness.
This test provides a measure of resistance to tearing. Tear strength may also be used to illustrate the anisotropy of a material.
Testing is performed by pulling specimens apart using a tensile test machine. The maximum force required to tear a test specimen is used to calculate the tear strength of the Die A, B, and C specimens while the mean force is used for the T and CP specimens.
|Die A||Nicked Crescent||500 mm/min (20 in/min)|
|Die B||Nicked Tab End||500 mm/min (20 in/min)|
|Die C||Right Angle||500 mm/min (20 in/min)|
|T||Trouser||50 mm/min (2 in/min)|
|CP||Constrained Path||50 mm/min (2 in/min)|
