This part of ISO 6892 specifies the method for tensile testing of metallic materials and defines the mechanical properties which can be determined at room temperature.The shape and dimensions of the test pieces may be constrained by the shape and imensions of the metallic product from which the test pieces are taken.The test piece is usually obtained by machining a sample from the product or a pressed blank or casting.However, products of uniform cross-section (sections, bars, wires, etc.) and also as-cast test pieces (i.e. for cast iron and non-ferrous alloys) may be tested without being machined.The cross-section of the test pieces may be circular, square, rectangular, annular or, in special cases, some other uniform cross-section.
