DIN 53357 is a historical German technical standard titled "Testing of plastics sheet; adhesion test" (Prüfung von Kunststoff-Folien; Trennversuch).
Although it is a widely referenced standard for measuring the bond strength of laminated materials and plastic sheets, it was officially withdrawn in November 2013 and has not been directly replaced by a single successor. Key Technical Details
Based on its application in industry datasheets and testing guides, the standard typically involves the following:
Primary Objective: To determine the adhesion or peel strength of plastic sheets and laminated materials. Testing Method:
Peel Angle: The standard is often divided into Method A and Method B. DIN 53357-B specifically refers to a 90-degree peel angle test.
Apparatus: Requires a tensile testing machine capable of maintaining a specific constant speed, often 100 mm/min.
Measurement: Results are typically expressed in units of force over width, such as N/5cm or kg/5cm. Common Applications: din 53357 pdf
Testing the bond between layers in automotive interior laminates.
Measuring the adhesion of coatings on outdoor billboard and banner fabrics.
Determining the bond strength of pressure-sensitive tapes and laminated release coatings. Availability and Replacement
Because the standard is withdrawn, "long content" or the full text is primarily available through archives or specialized standard distributors:
Official Purchase: You can still obtain the 1982-10 version in German or English from Intertek Inform or DIN Media.
Modern Alternatives: For new projects, engineers often use DIN EN ISO 2411 (for rubber- or plastics-coated fabrics) or ISO 8510-1/2 (for adhesives and peel tests) as contemporary substitutes for adhesion testing. DIN 53357 - 1982-10 DIN 53357 is a historical German technical standard

The current version of DIN 53357 was reaffirmed in 2020 (with corrections from 2017). Do not use a version older than 2010, as reference oils have changed.
Modern vehicles contain hundreds of rubber and plastic parts—fuel lines, O-rings, tank gaskets, and engine mounts. Exposure to E10, biodiesel, or synthetic motor oil can cause degradation. DIN 53357 allows manufacturers to predict failure points before mass production. Option 4: University or Institutional Access If you
DIN 53357 is a German industrial standard that describes a test method for determining the behavior of rubber and plastics when subjected to liquid media—specifically oils, fuels, and other fluids. The full title translates to: "Testing of rubber and plastics - Determination of the behavior when exposed to liquid media."
The standard is widely used in the automotive, aerospace, industrial machinery, and petrochemical sectors. It helps predict how seals, gaskets, hoses, and other polymer-based components will perform over time in oily or fuel-rich environments.
When a seal swells or a gasket cracks in the field, engineers replicate the service conditions using DIN 53357 to investigate the root cause.
Results are reported as percentage change:
Engineers typically need this standard for:
If your component touches oil, fuel, or hydraulic fluid, someone has likely specified DIN 53357 somewhere in the supply chain.
