There are many tests in this specification including tests for density, ball rebound, airflow, etc. However, the most common tests in the specification areASTM D1621 | Plastics and Elastomers | Compression Testing. Prepare the specimen as described in the standard. The specimen should be square or circular in cross section with a minimum of 25.8 cm 2 (4 in 2) and maximum of 232 cm 2 (36 in 2).Minimum height should be 25.4 mm (1 in) and the maximum height shouldn’t exceed the width or the diameter of the specimen.

ASTM D3574 Test C and ISO 3386 both measure the force deflection properties of flexible polyurethane foam at a constant test speed, or rate of extension (CRE). The test is setup to measure the force required to compress the test sample to a level of 50 per cent of thickness. The sample is placed between two compression platens that are larger than the sample size. Significance — The data obtained from a compression test may include the yield strength, the yield point, Young's modulus, the stress-strain curve, and the compressive strength (see Terminology E6).In the case of a material that does not fail in compression by a shattering fracture, compressive strength is a value that is dependent on total strain and specimen .Foam Compression Fixture, 10 kN ( 907 kg, 2000 lbf).
