However, DIN 53507 was not harmonized with international standards. This led to confusion, especially for companies exporting rubber goods to global markets. As a result, DIN officially withdrew this standard and replaced it with an international equivalent.

DIN 53507 is a critical historical German industrial standard used for testing rubber and elastomers, specifically to determine their tear propagation resistance using a trouser test piece. While it was officially withdrawn in 1983 and largely replaced by international standards like ISO 34-1, it remains a fundamental reference in elastomer technology.  Core Concept: Tear Propagation Resistance 

Unlike tensile strength, which measures the force needed to break an undamaged sample, tear propagation resistance focuses on the "worst-case scenario". It measures how much force is required to further pull apart a material that already has a small cut or notch. 

Significance: For industrial components like O-rings, seals, and gaskets, this value is vital because it determines how a part will behave if it is slightly damaged during assembly or stressed by sharp edges.

Measurement: Results are typically expressed in N/mm (Newton per millimeter), representing the force required per unit of material thickness.  The Trouser Test Method 

The standard defines the geometry of the test specimen, known as the "trouser test piece". 

Shape: The specimen is a flat strip with a longitudinal cut down the center of one end, creating two "legs". din 53507 pdf

Procedure: These legs are clamped into a tensile testing machine and pulled in opposite directions.

Observation: The machine measures the force needed to continue the tear from the base of the initial cut through the rest of the strip.  Modern Relevance and Transition 

Although DIN 53507 is technically obsolete, you will still find its legacy in technical data sheets for heavy-duty industrial materials: 

Sika Waterbars: High-performance PVC-P products often cite DIN 53507 A for tear strength specifications (e.g., values ).

Standardization: Most modern labs have shifted to ISO 34-1 or DIN ISO 34-1, which harmonize these testing procedures globally to ensure consistent material quality across international borders.  DIN 53507 - 1983-03

in 2004, it remains a foundational reference in elastomer technology for characterizing "notch sensitivity"—the material's ability to resist further tearing once a cut or damage has already occurred. Intertek Inform 1. Scope and Objective

Unlike a standard tensile test which measures the force required to break an undamaged specimen, DIN 53507 specifically assesses the worst-case scenario

: how easily a pre-existing cut or notch propagates through the material. This is critical for industrial components like O-rings, seals, and membranes that may suffer minor assembly damage or surface nicks during operation. Kremer-tec.de 2. Test Methodology The standard utilizes the Trouser Test

geometry, so named because the specimen is cut into two "legs" that resemble trousers. Hepako GmbH Specimen Preparation Go to www

: A narrow rubber strip (typically 100mm long and 2mm thick) is given a defined longitudinal pre-slit.

: The test is conducted using a universal tensile testing machine.

: The two "legs" of the specimen are clamped into separate grips of the machine. The grips separate at a constant rate—specified as 100 mm/min

in the 1983 edition—pulling the legs apart and propagating the tear along the length of the strip. Data Recording

: A force-distance diagram is recorded during the tearing process to capture the peak and average forces required to sustain the tear. 3. Evaluation and Units The primary result is the Tear Propagation Resistance ( cap T sub s , expressed in Newtons per millimeter (N/mm)

. This value represents the force required to propagate the tear divided by the thickness of the material. Kremer-tec.de 4.

: Sulfur-cured vs. peroxide-cured systems change the network density and tear behavior.

: The quantity and type of carbon black or silica can increase tensile strength but sometimes decrease tear resistance if the compound becomes too brittle. Temperature

: Rubber modulus and tear resistance are highly temperature-dependent; tests are typically standardized at Kremer-tec.de

DIN 53507 is a historic German industrial standard for determining the tear propagation resistance of rubber and elastomers using a "trouser" test specimen.

As of March 1998, this standard has been withdrawn and replaced by the international standard DIN ISO 34-1, which provides the current requirements for tear strength testing. Quick Guide to DIN 53507 (Historical Context)

Purpose: Measures the force required to propagate a cut in a rubber sample.

Test Specimen: Uses a "trouser" shaped specimen (Test Piece A) approximately 100 mm long and 2.0 mm thick.

Measurement: Results are typically expressed in N/mm (force per unit thickness). Higher values indicate better resistance to cuts and operant damage.

Replacement: For modern compliance, refer to DIN ISO 34-1 (Method A for trouser specimens). Where to Find Full Documents

Because DIN 53507 is withdrawn, it is primarily available through archives or standard resellers:

Current Standards: You can purchase the replacement, DIN ISO 34-1, from official retailers like DIN Media (formerly Beuth Verlag).

Historical Reference: Full archival copies of the 1983 edition can occasionally be found on document sharing platforms like Scribd for research purposes. Din 53507 | PDF - Scribd

DIN 53507 is a German standard that specifies a test method for determining the resistance of elastomers (rubber materials) to accelerated aging in air — typically an oven aging test that measures changes in physical properties (hardness, tensile strength, elongation) after exposure to elevated temperature for set times.
