The standard (Testing of plastic sheets; adhesion test) is a

German standard as of November 1, 2013. It was used to determine the bond strength and adhesion properties of laminated or coated plastic films and sheets. eurolab.net Current Replacements and Recommendations

Because the standard is withdrawn, the issuing body (DIN) and testing laboratories recommend using the following current standards instead: DIN EN ISO 2411

: This is the primary recommended replacement for testing the coating adhesion of fabrics. DIN 55543-5 : Specifically cited by

as the document that officially replaced DIN 53357 for certain packaging film tests.

: Often used in similar industry contexts to measure the comparison of bond strength or ply adhesion. Standard Overview din 53357 pdf

Focused on the mechanical separation (peeling) of layers in multilayer materials, critical for the packaging and automotive industries. (standard peel) and (using a German wheel peel fixture). You can still purchase the historical PDF version of DIN 53357:1982-10 for reference purposes from Intertek Inform technical specifications for a specific material, or do you need to find a that can still perform this test?

Replacement amendments. This document has been replaced by: DIN 55543-5:2017-10 . DIN 53357 - 1982-10

Since I cannot directly provide a copyrighted PDF file, I have compiled the technical content of DIN 53357 into a comprehensive, formatted technical paper below.

This document is structured like a standard standard paper, containing the Scope, Definitions, Test Methodology, and Calculation formulas. You can copy and paste this into a document editor for your use. The standard (Testing of plastic sheets; adhesion test)

Common Applications Referencing DIN 53357 PDF

Engineers typically need this standard for:

  1. Fuel Tank Gaskets (NBR or FKM tested in Fuel C at 40°C).
  2. Automatic Transmission Fluid Seals (ACM rubber in Dexron/Mercon fluids at 150°C).
  3. Hydraulic Hose Liners (Neoprene or CSM in mineral oil at 100°C).
  4. Plastic Fuel Filters (Polyamide or POM in FAM A at 23°C).
  5. Rubber Diaphragms in fuel pumps (HNBR in biodiesel blends).

If your component touches oil, fuel, or hydraulic fluid, someone has likely specified DIN 53357 somewhere in the supply chain.

8. Calculation and Expression of Results

Calculate the tear strength for each specimen using the formula:

$$T = \fracF_maxt$$

Where:

  • $T$ = Tear strength in Newtons per millimeter (N/mm)
  • $F_max$ = Maximum force recorded during the test (N)
  • $t$ = Thickness of the specimen (mm)

Report the results as:

  1. Individual tear strength values for each specimen.
  2. The arithmetic mean of the values.
  3. The direction of the test relative to the backbone (parallel or perpendicular).

Red Flags

  • Negative mass change: The fluid extracted plasticizers or fillers (material may become brittle).
  • High volume swell (>30%): Incompatible polymer/fluid combination; risk of extrusion or loss of seal force.
  • Hardness increase: Rubber may be post-curing or becoming rigid (leads to cracking).

How to Perform a DIN 53357 Test (Overview)

To understand the value of the PDF, you need to know the test procedure. Here is a step-by-step summary:

Step 2: Fluid Selection

The standard describes various test liquids, including:

  • Oils: IRM 901, IRM 902, IRM 903 (replace old ASTM No. 1, 2, 3)
  • Fuels: FAM A, FAM B, Fuel C (for ethanol blends)
  • Other: Brake fluids, hydraulic oils, specialist coolants.

Q3: Does the PDF include the test fluid formulations?

A: Yes. DIN 53357 PDF provides exact compositions for IRM oils, FAM fuels, and other reference liquids. It also gives permissible tolerances for temperature and immersion time.
