The original version was published in . By July 1, 2004 , it was officially superseded. This means a newer version or a replacement document has taken its place. The primary reason for this change was the harmonization of German national standards with international ISO standards. The content and methodology of DIN 53507 have been effectively replaced by the international standard DIN ISO 34-1 , titled "Rubber, vulcanized or thermoplastic - Determination of tear strength".
The DIN 53507 standard specifies the following test parameters:
If you are looking for the modern equivalent of the , you should seek DIN ISO 34-1 . This updated standard provides the current regulations for the trouser test piece method.
The fundamental concept it defined is simple but crucial: once an elastomer component has a cut or nick, how much force is required to make that tear continue to propagate? This property is distinct from tensile strength, which measures the force needed to tear a completely intact sample. The test method used a specific "trouser-shaped" test piece (Streifenprobe) and a tensile testing machine to measure this resistance, with results expressed in Newtons per millimeter (N/mm). din 53507 pdf updated
: A force-distance diagram is recorded during the tearing of the specimen. The peak values of force recorded during this process are used to calculate the tearing strength ( ).

Tear propagation resistance differs fundamentally from standard tensile strength testing. While tensile strength tests evaluate a material's capability to withstand an initial fracture under maximum load, tear propagation testing measures how effectively a material . DIN 53507 - 1983-03
This method, along with a complementary test (DIN 53515, the Graves angle test), provided a quantitative measure of a material's resistance to tearing under duress. The result was a key indicator of an elastomer's notch sensitivity—the more sensitive a material, the more easily a cut or nick would lead to catastrophic failure.
Tear resistance is distinct from tensile strength; while tensile strength measures the force needed to break a material, tear propagation measures the force required to continue a crack in a material that has already been damaged or notched.
), dividing the required force by the thickness of the specimen. This yields a clean, geometry-independent metric representing the energy required to tear through a unit depth of the elastomer. 3. The Evolution and "Updated" Status of DIN 53507
