This test method is used to measure the tear resistance in vulcanized rubbers and thermoplastic elastomers. The tests can be used to predict the point of failure (tear) when a product is in service.

Test Details

This test method is used to evaluate the tear strength of common vulcanized rubbers and thermoplastic elastomers. Tear strength can be influenced by mechanical fibering (surface cracking), stress distribution, strain rate, and size/dimensions of the test specimen. Therefore, the tests used to predict tear resistance should have a direct correlation to the service conditions during testing.

Types of products / materials generally tested in our laboratory under this method:

  • Vulcanized rubber
  • Thermoplastic materials

*Please Note: The information outlined above is to be used as reference for ASTM D624 Standard Test Method for Tear Strength of Conventional Vulcanized Rubber and Thermoplastic Elastomers and ISO 34-1 Rubber, vulcanized or thermoplastic -- Determination of tear strength -- Part 1: Trouser, angle and crescent test pieces. Please refer to the appropriate standards agencies for full details and the most current revisions.
