In a similar test for the shear strength of solid wood, Test Methods D143, these effects are self correcting so that the measured strength is close to the true shear strength of the wood. By analogy the same may be true in this .ASTM D695 Test Systems. Test samples are end loaded in compression using low test speeds. A universal test machine with constant rate of crosshead displacement is commonly configured with ASTM D695 test fixtures. Depending on the maximum expected forces, either a single column or dual column universal testing machine works.Compression testing is one of the most fundamental types of mechanical testing, alongside tensile and flexion tests. Compression tests are used to determine a material’s behavior under applied crushing loads, and are typically conducted by applying compressive pressure to a test specimen (usually of either a cuboid or cylindrical geometry) using platens or specialized .
