Note: This test standard aligns with ISO 604. Test Procedure for ASTM D695. Specimen Measurement: Measure the specimen's width and thickness (or diameter) at multiple points along its length to an accuracy of 0.025 mm (0.001 in.). Calculate the minimum value of the cross-sectional area and document. Measure and record the length of the specimen.
Compressive Strength Testing of Plastics. The compressive strength of a material is the force per unit area that it can withstand in compression. This is in contrast to the more commonly measured tensile strength. ASTM D695 is the standard test method in the USA. The figure below, from Mitsubishi Chemical Advanced Materials, shows the test .While in EN 826 and ISO 844 the movement of the compression platen is typically measured by the crosshead travel of the testing machine with a defined minimum accuracy, ASTM D1621 describes an additional method that compensates for the self-deformation of the testing machine. Alternately, all standards permit direct displacement measurement of .
