For professionals in the plastics, packaging, and automotive industries, material durability is non-negotiable. One critical property is tear resistance, especially for films, foils, and flexible sheets. The German standard DIN 53357 provides a precise method for measuring this property. If you are searching for the “DIN 53357 PDF,” this guide explains what the standard covers and how to obtain it.

A rectangular test specimen with a pre-cut slit or notch is placed in a tensile testing machine. The specimen is pulled in such a way that the tear propagates from the pre-cut area. The maximum force required to continue tearing the leather is recorded. If you meant you need a review of
It is common to confuse DIN 53357 with international equivalents. Here is a quick comparison:
| Standard | Title | Key Difference | | :--- | :--- | :--- | | DIN 53357 | Testing of rubber and plastics – liquid media exposure | German standard; historically used more in Central Europe. Often references specific test fluids (e.g., IRM 901, Fuel C). | | ISO 1817 | Rubber, vulcanized or thermoplastic – Determination of the effect of liquids | International version. Very similar in methodology. Many modern labs treat DIN 53357 as equivalent to ISO 1817. | | ASTM D471 | Standard Test Method for Rubber Property—Effect of Liquids | US standard. Uses different reference oils (e.g., ASTM Oil No. 1, 2, 3 vs. IRM oils). Temperatures may vary. |
Important: When a client asks for a DIN 53357 PDF, verify whether they explicitly require the German method or if they accept ISO 1817. Many modern testing houses have replaced DIN 53357 with ISO 1817, but older specifications still cite the DIN number.
