Hardness testing (indentation method)
The purpose of this test is to determine the compressive strength of the test specimen (the force required to compress the specimen by 40% of its thickness) and to determine whether the foam is comfortable enough for use in a seat.
The test involves measuring the forces required to produce specified indentations under prescribed conditions. The specimen is compressed to 25%, 40%, 65%, and 70% of its initial thickness; the forces required for compression are then measured, and these correspond to the indentation hardness values.
