ASTM D3574 Flexible Cellular Materials-Slab, Bonded, and Molded Urethane Foams
ASTM D3574 is a set of standard test methods used to evaluate the physical properties of flexible cellular materials used for cushioning, packaging, and insulation. The tests include measurements for density, compression force deflection, tear strength, and other properties to ensure that the materials meet industry standards and customer specifications.
GET STARTED
Introduction to ASTM D3574
ASTM D3574 is a collection of test methods developed by the American Society for Testing and Materials (ASTM) to evaluate the physical properties of flexible cellular materials used for cushioning, packaging, and insulation. These materials include foams made from polyurethane, polyethylene, and other polymers, as well as natural rubber and cork. The purpose of these test methods is to ensure that the materials meet the required specifications and can perform their intended functions. The results obtained through this method are especially used for quality control, reliability check, performance evaluation, and specification purposes.
ASTM D3574 is a standard test method generally applied to determine the properties of flexible cellular materials such as slab, bonded, and molded urethane foams. The test method covers a range of properties, including density, compressive strength, tear strength, resilience, and fatigue.
ASTM D3574 Test Method
The test method ASTM D3574 consists of a series of tests that measure the physical properties of the flexible cellular materials. These tests include the determination of density, compression deflection, tear resistance, tensile strength, elongation, and resilience. The tests are conducted on samples that have been conditioned at a specific temperature and humidity level for a specific period of time.
Density
This test method determines the mass per unit volume of a foam specimen.
Compression Force Deflection (CFD)
This test method measures the force required to compress a foam specimen to a specified percentage of its original thickness.
Tensile Strength and Elongation
These test methods measure the force required to break a foam specimen and the percentage of elongation at break.
Tear Strength
This test method measures the force required to tear a foam specimen.
Resilience
This test method measures the ability of a foam specimen to recover its original shape after compression.
Indentation Force Deflection (IFD)
This test method measures the force required to indent a foam specimen to a specified depth.
Compression Set
This test method measures the permanent deformation of a foam specimen after compression.
Dynamic Fatigue
This test method measures the ability of a foam specimen to withstand repeated compressions and recover its original shape.
ASTM D3574 Specimens
Specimen details
ASTM D3574 requires materials such as slab, bonded, and molded urethane foams.
Specimen dimensions
The acceptable specimen thickness for ASTM D3574 depends on the specimen being used.
Specimen preparation
To perform the test, samples are cut from the foam material in a specific shape and size, and are conditioned at a specific temperature and humidity level for a specific period of time.
ASTM D3574 Results
The results of ASTM D3574 tests are used to determine whether a foam material meets the required specifications for its intended use. These test results can also be used to compare different materials and to identify potential areas for improvement in material design and manufacturing processes.
Tests related to ASTM D3574
Other related tests include ASTM D1621, which measures the compressive properties of rigid cellular plastics, and ASTM D3575, which measures the properties of flexible cellular materials made from olefin polymers. These tests provide additional information about the properties of foam materials, and can be used in conjunction with ASTM D3574 to evaluate the quality of the material.
