Yes. The current version is DIN 53357:2020-08 (published August 2020). It replaces older versions from 2014, 2006, 1981, etc.
Determination of Density of Plastics according to DIN 53357
: Uses a specialized rotating wheel fixture (often called the German Wheel ) to maintain a constant 90-degree peel angle throughout the test, ensuring high precision for flexible materials. din 53357 pdf
The test involves separating two layers of a sample at a specific speed and measuring the force required.
Peel force, usually expressed in Newtons (N) or Newton/centimeter (N/cm). DIN 53357 Test Methodology Determination of Density of Plastics according to DIN
DIN 53357, officially titled "Testing of plastic sheets and films - Separation test of layers" (or "Adhesion test"), was a German standard published by the Deutsches Institut für Normung (DIN), the German Institute for Standardization. Its primary purpose was to define a clear, repeatable laboratory procedure for determining the force required to separate the individual layers of multi-layer plastic products, such as laminates, coated films, and coextruded sheets. This information is crucial for quality control in manufacturing industries where the integrity of the bond between layers directly impacts the product's performance and durability.
Along with the force, technicians evaluate how the material fails (e.g., adhesive failure, cohesive failure, or tear). Applications and Importance DIN 53357 Test Methodology DIN 53357, officially titled
Typically 50 mm for composite sheets; 15 mm for thin multi-layer films. Method B (Split Test):
The standard outlines specific procedures for preparing samples and conducting tests using a tensile testing machine (often combined with a German Wheel Peel Fixture ). Methods: A vs. B
