Tear propagation resistance measures how well an elastomer resists the further tearing of a material that has already been notched or cut. This is distinct from tensile strength, which measures the force required to tear an undamaged sample. This parameter is critical for assessing in components like:

The DIN 53507 PDF document provides detailed information on the testing procedure for determining the tear resistance of elastomers. The standard outlines the following:

The scope of DIN 53507 includes:

Do not waste time searching for a free, illegal PDF of DIN 53507—it will likely lead to outdated or malicious files. Instead, adopt ISO 34-1 for current testing, or purchase the historical document from a certified standards retailer.

: The specimen is a flat strip with a longitudinal cut down the center of one end, creating two "legs".

The standard DIN 53507 applies to vulcanized rubber and thermoplastic elastomers, including:
