Belts carrying sharp rocks or metals cannot allow a small puncture to turn into a full-length split.
The core objective of DIN 53507 is to measure an elastomer’s sensitivity to notch damage and its ability to withstand the expansion of an existing cut under tensile load. DIN 53507 – Tear Resistance of Elastomers - Power Rubber
In the global effort to harmonize standards, many national standards have been superseded by International Organization for Standardization (ISO) standards.
The standard defines a specific procedure to quantify how easily a tear travels through a pre-damaged material: Test Specimen din 53507 pdf
Typically 2.0 ± 0.2 mm (Test Piece A) or 6.3 ± 0.3 mm (Test Piece B).
DIN 53507, though a withdrawn standard, played a significant role in the history of materials testing. It established a crucial method for understanding a key failure mechanism in rubber and elastomers:
While both standards relate to tear resistance, they use different test specimens: Belts carrying sharp rocks or metals cannot allow
The test equipment required for DIN 53507 includes:
If you are searching for the , you are likely running into its "retirement" story: DIN 53507 - 1983-03
DIN 53507 provides standard guidelines for calculating how well an elastomer material resists the extension of an existing cut or nick. Unlike traditional tensile testing—which measures the force needed to snap a pristine, uncut piece of material—tear propagation testing evaluates structural vulnerability after an initial physical injury has already occurred. Core Technical Objectives The standard defines a specific procedure to quantify
This test, known as the strip test or trouser test, was one of two classic methods used historically. The second was the Graves angle test, specified in the now-withdrawn .
This article provides a comprehensive overview of the DIN 53507 standard, its purpose, test procedures, and the key terminology found in the documentation. 1. What is DIN 53507?
During the test, the testing machine continuously measures the force required to propagate the tear. This force is then calculated relative to the thickness of the specimen. The final result is the , which is expressed in Newtons per millimeter (N/mm) .
