The is a critical benchmark for testing the adhesion of plastic sheets and films , specifically focusing on the separation of layers in laminated or coated materials . While the official document was withdrawn in 2013 and replaced by DIN EN ISO 2411 , it remains a widely cited reference in historical data and specific industrial quality control protocols for multilayer packaging and adhesive tapes. Core Purpose of DIN 53357
It is common to confuse DIN 53357 with international equivalents. Here is a quick comparison:
The core piece of equipment for the DIN 53357 test is a tensile testing machine that meets the requirements of DIN 51220 and DIN 51221. The machine's measuring range must be selected such that the average separation force does not fall within the first fifth of the device’s measurement range. Additionally, a special clamping device for peel tests is required, with a defined peel roller (so-called "German Wheel Peel Fixture") that complies with DIN 53357-B. din 53357 pdf
The most important takeaway: If you need a legally valid test specification, the withdrawn DIN 53357 is not sufficient. You should instead switch to the replacement standards , DIN EN ISO 11339 , or DIN EN ISO 2411 , depending on the specific application. In most laboratories, these modern standards have taken the place of the former German adhesion test method for plastic sheets.
Because the standard is withdrawn, it may be challenging to find a free PDF online. For official, legally binding copies, your best recourse is to purchase the PDF from authorized standards distributors: The is a critical benchmark for testing the
standard, titled "Testing of plastic sheets; adhesion test," specifies methods for determining the separation force
: A tensile testing machine (universal testing machine) conforming to DIN 51220 and DIN 51221 standards was required. The force measurement device needed to have a low inertia and be at least Class 1 accuracy. A key piece of equipment was a specialized peel wheel fixture (often referred to as a "German wheel" for test method B). This fixture held the specimen at a constant 90-degree angle throughout the test, ensuring a consistent and repeatable peel angle. Here is a quick comparison: The core piece
Impact resistance testing is essential for evaluating the performance and safety of rigid plastics. A high impact resistance indicates that a material can withstand rough handling and harsh environmental conditions. This property is critical in applications where plastic materials are exposed to impact, such as in automotive components, construction profiles, and packaging materials.
: One separated end of the specimen was gripped in the machine's stationary jaw, while the other was attached to the peel wheel. As the crosshead moved, the wheel rotated, peeling the material at a constant 90° angle and a specified constant speed, and the required force was recorded.
is the historical German testing standard used to evaluate the adhesion strength and layer separation of laminated, coated, or bonded plastic sheets and films . Published by the German Institute for Standardisation ( Deutsches Institut für Normung ), this standard outlines the precise methodology for performing mechanical peel and delamination tests. In manufacturing sectors like flexible packaging, automotive interiors, and multi-layer structural films, downloading and adhering to a DIN 53357 PDF document ensures that composite materials resist separation under mechanical stress. 1.
