ASTM E8 Tensile tests provide information on the strength and ductility of materials under uniaxial tensile stresses. ASTM E8 covers tension testing of metallic materials in any form at room temperature, specifically, the methods of determination of yield strength, yield point elongation, tensile strength, elongation, and reduction of area. The gage lengths for most round specimens are required to be 4D for E8 and 5D for E8M. The gage length is the most significant difference between E8 and E8M test specimens. ASTM E8 test procedures call you to zero the test machine, inset the test sample into the chosen grip type, select or determine test mode of control (constant stress rate, constant strain rate or constant crosshead travel speed), set the test speed and start the test. There are many variables involved with this test including aspects around machine control.
