DIN 53357 is a withdrawn German standard titled "Testing of plastics sheet; adhesion test" (Prüfung von Kunststoffbahnen und -folien; Trennversuch). It describes methods for determining the peel strength or interlayer adhesion of plastic sheets and coated fabrics. Standard Status & Content

Status: Withdrawn as of November 1, 2013. It has largely been replaced by newer standards like DIN EN ISO 11339 or DIN 16726 depending on the specific application. din 53357 pdf

Scope: The test measures the force required to separate two layers of material. It is commonly used for coated fabrics (like PVC-coated nylon) and multilayer polymer-based pipes. Methods: Method A: General adhesion test for plastic sheets.

Method B: Often associated with the "German wheel" or rotating wheel peel test, used to maintain a constant 90∘90 raised to the composed with power peel angle. Where to Access

Since this is a copyrighted technical standard, full "text" PDFs are typically not available for free legally, though some third-party document sharing sites may host copies.

Official Purchase: You can purchase the historical standard from DIN Media or the ANSI Webstore.

Technical Summaries: Many testing equipment manufacturers provide datasheets summarizing the test requirements, such as this Peel Fixture Datasheet from Morsetti Universali or Grip Engineering. DIN 53357 - 1982-10

DIN 53357 was a historical German standard used to test the adhesion (peel strength) of laminates and plastic films. Although it was officially withdrawn in the late 1990s and replaced by newer European standards, it remains a common reference in technical data sheets for legacy industrial materials. 1. Purpose and Scope

The primary goal of DIN 53357 was to determine the strength of the bond between layers of flexible materials. This is critical for: Plastic films and laminates. Synthetic leather (PVC/PU coated fabrics).

Adhesive-backed foils used in automotive and construction industries. 2. Testing Methodology

The test measured the force required to separate two bonded layers under specific conditions: Peel Angle: Typically a 90-degree or 180-degree peel test.

Constant Rate: The specimen was pulled apart at a fixed speed (usually 50 mm/min or 100 mm/min).

Measurement: The result was expressed in N/cm (Newtons per centimeter) or N/15mm, representing the average force needed to sustain the peeling process. 3. Current Status: Withdrawn and Replaced DIN 53357 is a critical historical technical standard

You will often find "DIN 53357" in PDF catalogs for older products, but for modern compliance, it has been superseded by:

DIN EN ISO 2411: Specifically for rubber- or plastics-coated fabrics (determination of coating adhesion).

DIN EN 28510-1 / ISO 8510-1: For general adhesives and peel tests for flexible-to-rigid bonded assemblies. 4. Why is the PDF still sought after?

Engineers and quality control specialists often look for the original DIN 53357 PDF to:

Compare legacy data: When a manufacturer’s datasheet still lists values according to the old standard.

Maintain continuity: For long-term projects (like aerospace or infrastructure) that were spec'd decades ago and require the exact original testing parameters. Summary Table Full Title

3. Definitions

For the purposes of this standard, the following definitions apply:

3.1 Tear Force ($F$): The maximum force applied to a test specimen to cause a tear to propagate, measured in Newtons (N).

3.2 Tear Strength ($T$): The tear force divided by the thickness of the test specimen. It represents the material's resistance to tearing independent of its thickness. $$T = \fracFt$$ Where: Ensure product quality : By following DIN 53357,

  • $T$ = Tear strength (N/mm)
  • $F$ = Maximum tear force (N)
  • $t$ = Thickness of specimen (mm)
