ASTM D1621 Method for Compressive Properties of Rigid Cellular Plastics

ASTM D1621 test method determines the compressive properties of hard cellular materials, namely expanded plastics. This test method provides information on the compressive properties of cellular materials, including compressive strength, modulus of elasticity, and deformation characteristics. The data, i.e., the complete load-deformation curve, obtained by ASTM D1621 test method can be used to compute the compressive stress at any load (such as compressive stress at proportional-limit load or compressive strength at maximum load) and to compute the effective modulus of elasticity.


Introduction to ASTM D1621

The ASTM D1621 test method gives information about the compressive behavior of cellular materials. By gathering test data and utilizing a complete load-deformation curve, it becomes possible to compute the compressive stress at any load (e.g., compressive stress at the proportional-limit load or compressive strength at the maximum load) as well as the effective modulus of elasticity. Compression tests are used to obtain data for research, quality control, acceptance, and special purposes.

The data obtained from ASTM D1621 test method is used for research and development, quality control, acceptance or rejection under specifications, and special purposes. MaTestLab has the best network of testing labs in the USA to carry out ASTM D792 test for clients.

ASTM D1621 Standard Test Method

Test SetupThe testing machine is equipped with load and deformation measuring devices to apply a compressive force at a controlled rate. The specimen is placed between two compression plates, and the dimensions are measured and recorded before the compressive force is applied.
ProcedureA compressive force is applied to the specimen at a constant rate until it fails or reaches a specified deformation or load level, depending on the requirements of the test.
Data CollectionThe highest amount of pressure that the specimen can withstand when compressed, along with the associated amount of deformation or strain, is measured and recorded until the test is finished.

ASTM D1621 Test Specimen

Specimen detailsASTM D1621 is a test method for compressive properties of rigid cellular plastics with a minimum of five specimens per sample.
Specimen dimensionsThe most important idea is that the specimen must have a minimum area of 25.8 cm2 (4 in.) and a maximum area of 232 cm2 (36 in.).
Specimen preparationThe loaded ends of the specimen should be parallel to each other and perpendicular to the sides. If the material is suspected to be anisotropic, specify the direction of compressive loading relative to the suspected direction of anisotropy.

ASTM D1621 Test Results

A test report is prepared with all relevant information, including specimen details, test conditions, results, observations, and deviations from the standard. Information about the testing machine, calibration, and other pertinent details should also be included.

Other Tests Related to ASTM D1621

ASTM D1621 is related to other tests, including ASTM D618 for conditioning plastic for testing and ASTM E4 for force verification of testing machines.
