ASTM E8 Tensile Test Specimens
Metal tensile test specimens for ASTM E8 (Tension Testing of Metallic Materials). These test specimens may be made from a wide range of metal alloys, including aluminum, steel, stainless steel, and cast metals. ASTM E8 describes two specimen types, standard or full-size specimens and subsize specimens. Both specimen types have the same shape: a flat bar with a reduced diameter in the center. Tensile specimens are sometimes referred to as dogbone specimens for this shape.
ASTM E8 specimens are also used in testing by ASTM G129 and ASTM G49.
