Din: 53357 Pdf [verified]

Technical Overview: DIN 53357 (Testing of Plastic Sheets; Adhesion Test) is a historically significant German standard used to measure the bond strength (adhesion) between layers of laminated or coated plastic sheets and films. Although officially withdrawn as of November 2013 , it remains a frequent reference in technical specifications for packaging, automotive interiors, and protective coatings. Intertek Inform 1. Scope and Core Purpose The standard provides a methodology for assessing the mechanical force required to separate the individual layers of a composite material. It is primarily applied to: eurolab.net Multilayer Plastic Films : Evaluating the integrity of food and medical packaging. Coated Fabrics : Ensuring coatings (like PVC or rubber) do not delaminate from their substrates. Adhesive Tapes : Measuring the peel strength of pressure-sensitive adhesives (PSA). 2. Key Test Methods DIN 53357 traditionally defined two primary approaches, often referred to as Method A and Method B: eurolab.net DIN 53357:1982-10 TESTING OF PLASTICS SHEET DIN 53357:1982-10 TESTING OF PLASTICS SHEET; ADHESION TEST.

Review: DIN 53357 – Testing of Plastics; Bending Test Type: German Industrial Standard (PDF format) Status: Withdrawn (superseded by DIN EN ISO 178) – Check if you need the current or historical version Overview DIN 53357 was a German standard specifically describing the bending test for plastics and elastomeric materials. It defined how to determine flexural properties such as bending strength, bending modulus, and deflection behavior. What the PDF Contains (Typical Structure)

Test principle: A supported beam (specimen) is deflected at a constant rate at its center (three-point bending). Specimen dimensions: Typically 80×10×4 mm (molded or machined). Test conditions: Span length, test speed (e.g., 2 mm/min or 14 mm/min depending on material), temperature. Calculation formulas: Bending stress, strain, and modulus. Precision & reporting: Statistical evaluation, number of specimens, conditioning requirements. din 53357 pdf

Strengths (Why you might need this PDF)

Historical reference: Essential if you are comparing old test data certified to DIN 53357 with newer results to ISO or ASTM. Specific German industry habits: Some German quality labs or legacy contracts still reference this withdrawn standard. Clear, concise setup: Like most DIN standards, it is methodical and less verbose than the international versions.

Limitations & Replacement

Withdrawn status: DIN 53357 has been replaced by DIN EN ISO 178 (identical to ISO 178). Do not use DIN 53357 for new product certifications unless explicitly required. Lacks modern updates: The ISO version includes additional details (e.g., four-point bending, precision data from interlaboratory tests, and support for fiber-reinforced plastics) not present in the old DIN. No ISO equivalence in old version: DIN 53357 was a purely national standard; the formulas and test speeds may differ slightly from ISO 178, so results are not directly interchangeable without conversion.

Recommendation

Buy/use this PDF only if: You must verify compliance with an old specification, or your customer/market specifically demands "DIN 53357" as a test method. Otherwise, use DIN EN ISO 178 (current, harmonized across Europe). If you already have access to ISO 178, you generally do not need DIN 53357.
