What Does a Tensile Test Determine?

A tensile test subjects a prepared specimen to controlled tensile loading until yielding and/or fracture. The test provides important information about the strength, ductility and deformation behaviour of the material.

Tensile testing may be used to determine ultimate tensile strength (UTS), yield strength, proof stress, elongation, reduction in area and other specified mechanical properties.

The results are commonly used for material qualification, quality control, incoming material inspection, manufacturing verification, product certification, research and development, welding qualification and engineering assessment.

Tensile Testing Standards

The applicable tensile testing standard depends on the material, product form, specification, specimen geometry, test temperature and customer or project requirements.

ASTM E8/E8M – Tension Testing of Metallic Materials

ASTM E8/E8M is widely used for tensile testing of metallic materials. Depending on the applicable requirements, tensile testing can determine yield strength, ultimate tensile strength, elongation and reduction in area.
