Tests Compliant with ASTM D 3574 Standard

Flexible foams are widely used in automotive, furniture, packaging, and sports equipment industries. Their mechanical strength, elasticity, and deformation properties are critical for product quality and safety. The ASTM D3574 Flexible Foam Testing Machine provides precise and reliable measurements of these properties, supporting production and quality control processes.

Main Purpose of the Machine

The machine is designed to measure the mechanical properties of flexible foam materials. It performs tensile, compression, and permanent deformation tests to objectively evaluate material performance.

Tests Performed by the Machine

  • Tensile Test: Measures the material’s tensile strength and elasticity.

  • Compression Test: Evaluates the material’s resistance to compressive forces.

  • Compression-Set Test: Determines the material’s resistance to long-term deformation.

  • Permanent Deformation Test: Measures shape changes under prolonged load.

  • Flexibility Test: Analyzes the elastic limits and durability of the material.

Importance and Purpose of Testing

These tests ensure quality control of flexible foams, allow early detection of production defects, and improve product safety. ASTM D3574-compliant tests enable objective and repeatable measurement of material performance.

Scientific Basis of Testing

Tests are based on Newtonian mechanics. The force applied to the material and resulting deformation are measured to calculate elastic modulus, tensile strength, and permanent deformation. ASTM D3574 ensures standardized evaluation of polyurethane foams and similar flexible materials.

Machine Usage

The machine’s touch screen and user-friendly interface allow easy testing. Test speed, force units, and stopping options can be set by the user. The sample is placed in the grips, the test cycle is started, and results are displayed and recorded.
