Covers the tensile testing of metals in the form of flat products, round and square bar, tube and wire. It includes definitions and symbols, the form and dimensions of standard test pieces and their preparation. Procedures are outlined for the determination of tensile properties at room temperature; yield stress, proof stress and proving tests for permanent set stress at different rates of straining; and the calculation of tensile strength, percentage elongation and percentage reduction of area. Notes on straining-rate control in the determination of yield stress, proof stress and permanent set stress, and guidance for committees drafting product specifications are in appendices.
