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 test relies on a distinct "trouser" shape. The test piece is a rectangular strip with a precut down the middle, creating two "legs" that are pulled in opposite directions.
Engineers use these results (recorded in N/mm ) to choose materials that won't catastrophically fail if they get a minor surface injury. Approximately €80–150 depending on VAT and user rights
If you are looking for the official test methodology, be sure to acquire the from a reputable standards source.
According to the standard, the values obtained using this method and do not directly predict the behavior of finished structural parts, particularly regarding other notch effects. This parameter is critical for assessing in components
Clamp one leg of the specimen into the top grip and the other leg into the bottom grip of the tensile tester.

You will frequently see DIN 53507 mentioned alongside . It is important to understand the difference, as they are alternative test methods for tear propagation resistance, not different standards for the same test.
