DIN 53357 is a German standard for "Testing of plastics; determination of the density of plastics". Here's a draft paper based on the standard:

Title: Determination of Density of Plastics according to DIN 53357

Introduction: The density of a plastic material is an important physical property that can affect its performance, processing, and applications. In this paper, we will discuss the method for determining the density of plastics according to the German standard DIN 53357.

Scope: This standard specifies a method for determining the density of plastics by measuring the mass of a specimen of known volume. The method is applicable to all types of plastics, including thermoplastics, thermosets, and elastomers.

Principle: The principle of the method is based on Archimedes' principle, which states that the buoyancy force exerted on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. By measuring the mass of the specimen in air and in a fluid of known density, the density of the specimen can be calculated.

Apparatus:

Test Specimen: The test specimen should be a rectangular prism or a cylindrical shape with a volume of at least 10 cm³. The specimen should be free from air bubbles and any other defects.

Procedure:

ρ_specimen = m_air / (m_air - m_fluid) * ρ_fluid

Calculations: The density of the specimen is calculated using the formula above. The result should be expressed in units of g/cm³ or kg/m³.

Precision and Accuracy: The precision of the method is ± 0.1% for densities up to 1.5 g/cm³ and ± 0.2% for densities above 1.5 g/cm³.

Conclusion: The determination of density of plastics according to DIN 53357 is a straightforward method that provides accurate results. The method is widely used in the plastics industry to characterize the properties of plastic materials.

Technical Report: DIN 53357 (Adhesion Testing of Plastic Sheets and Films)

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 While currently withdrawn, it remains a critical reference for quality assurance in industries such as packaging and manufacturing where laminated or coated materials are widely used.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 primary purpose of DIN 53357 is to measure the bond strength or ply adhesion of laminates made from flexible materials.

Adhesion Testing: Evaluates how well different layers of a material (e.g., in multi-layer packaging or adhesive tapes) are bonded together.

Material Types: Specifically designed for plastic films, sheets, and laminated structures where layer separation (delamination) is a potential failure mode.

Quality Control: Manufacturers use this standard to verify that materials meet performance criteria for durability and functionality. 2. Testing Methodology

The standard defines procedures for the layer separation test (Trennversuch der Schichten).

Method A: A common variant of the test often performed without a roller to determine the force required to peel layers apart.

Calculation: Bond strength is typically calculated as an average based on several measurement points (often 10) spread evenly across a specified measuring distance.

Performance Metrics: Results are often expressed in units such as Newtons per width (e.g., 96N/5cm) to quantify the force needed for separation. 3. Current Status and Successors

As of October 1982, the definitive version of the standard was DIN 53357:1982-10. However, it has since been withdrawn and replaced by newer international and local standards to align with global trade requirements.

Withdrawal Date: The standard was formally withdrawn in November 2013. Recommended Successors:

DIN EN ISO 2411: Specifically for rubber- or plastics-coated fabrics.

DIN 55543-5: Specifically for the testing of packaging films. 4. Technical Considerations

When interpreting results from DIN 53357, technical laboratories like Innoform Testservice note that:

Bending Stiffness: The inherent stiffness of the laminate layers can influence the measured bond strength. Directly comparing results from laminates with different stiffness levels can lead to misinterpretation of the actual adhesive bond. din 53357 pdf

Environmental Factors: Tests may be conducted across varying temperature ranges (e.g., -40°C to +120°C) to simulate real-world usage environments. 5. Document Availability

Though no longer an active standard, the historical document is still accessible for research and legacy compliance: Formats: Available in PDF and Hardcopy. Languages: Typically published in German and English.

Procurement: Can be purchased through technical standards libraries like DIN Media or Intertek Inform.

is a German technical standard used for the adhesion testing

of plastic sheets and films. It specifically outlines the "Layer Separation Test," which measures the force required to separate layers of a multi-layer material. Core Test Overview This standard is primarily used in industries dealing with laminates, packaging, and technical textiles

(such as architectural membranes). It describes two main methods for assessing how well layers are bonded together: Method A (Separation Test):

Focuses on separating five specimens (each 200 mm long) lengthwise and crosswise from the material web.

Typically 50 mm for composite sheets; 15 mm for thin multi-layer films. Method B (Split Test): A rectangular test specimen with a pre-cut slit

Uses five specimens (15 mm wide and 250–300 mm long) taken across the material slab. eurolab.net Technical Specifics The test is often performed using a 90° peel angle (also known as the German wheel peel test). Apparatus:

A tensile tester equipped with a specialized wheel extension (often 90 mm in diameter). A standard rate of 100 mm/min is commonly applied. The primary value evaluated is the maximum peel force

or average peel force (often expressed in N/5 cm or N/15 mm). Current Status It is important to note that DIN 53357 was withdrawn

in 2006. It has largely been superseded by international standards like DIN EN ISO 2411 (for rubber- or plastic-coated fabrics) or

(T-peel test for flexible-to-flexible bonded assemblies). However, it remains a frequent historical reference in technical datasheets for specialized materials like architectural membranes Common Applications Multilayer Pipes: Testing for rapid gas decompression resistance. Safety Glass: Evaluating the adhesion of anti-shatter films. Conservation: Testing adhesives used for lining old paper documents. ResearchGate

A primary feature of the DIN 53357 standard is its specialized peel testing methodology used to measure the bond strength and adhesion of laminated or coated plastic sheets and films. Key technical features of this standard include: Dual Testing Methods:

Method A (Separation Test): Typically involves specimens 200 mm long and 15 mm or 50 mm wide, pulled to test layer separation.

Method B (German Wheel Test): Uses a specialized rotating wheel fixture (often called the German Wheel) to maintain a constant 90-degree peel angle throughout the test, ensuring high precision for flexible materials.

Measurement Metrics: It focuses on determining the average separation force required to delaminate materials, providing a standard benchmark for quality control in packaging and industrial laminates.

Historical Context: Although widely used for decades, DIN 53357 is currently withdrawn as an active standard. It has largely been replaced by newer standards like DIN 55543-5 or international equivalents such as ISO 2411. DIN 53357 Test | Thwing-Albert
