These test methods cover the 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 Test specimens made from powder metallurgy (P/M) materials are exempt from this requirement by industry-wide agreement to keep the pressing
