The primary objective of is to evaluate the adhesion strength, specifically by measuring the force required to separate the layers of a laminated or multi-layer material. Primary Applications:
Using a tensile testing machine (often with a low-force capacity, such as a Thwing-Albert VantageNX ), the sample is pulled apart.
is a historical German standard titled "Testing of plastic sheets; adhesion test" ( Prüfung von Kunststoffbahnen und -folien; Trennversuch der Schichten ). It describes a specific method for assessing the adhesion force (separation force) between layers in multi-layer plastic sheets or between a top layer and its substrate.

The primary objective of the test is to measure the mechanical force required to separate multi-layer flexible structures, such as: Coated fabrics and textile materials. Multi-layer composite packaging films. Pressure-sensitive adhesive (PSA) tapes and labels.
The layers are manually separated at one end to allow clamping. The primary objective of is to evaluate the
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.
An edge of the composite strip is pre-separated or chemically delaminated to create manual "tabs" for initial gripping. The Peel Wheel Test Setup It describes a specific method for assessing the
DIN 53357 is a historical German technical standard established by the Deutsches Institut für Normung (DIN) that provides a consistent methodology for testing the mechanical adhesion properties of plastic sheets and films. While currently withdrawn, it remains a critical reference for quality assurance in industries such as packaging and manufacturing where laminated or coated materials are widely used. 1. Scope and Application
The ends are clamped directly into a tensile testing machine.
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.
