ASTM D642 & Other Compression Strength Tests
Materials behave differently in compression than they do in tension. Depending on the specific application, it can be important to perform mechanical tests which simulate these forces the material will experience in actual use.
Compression testing is typically used to test materials such as plastics, elastomers, rubber, composites, foam, rock, concrete and asphalt. It is rarely used to test metals.
Compression testing is also used in product testing to evaluate the behavior of finished products. For example, foam is compressed to determine how well it mantains its cushioning properties.
