This European standard specifies the method for
tensile testing of metallic materials and defines the mechanical properties that can be determined at ambient temperature. The test involves straining a test piece in tension, generally to fracture, for the purpose of determining one or more mechanical properties.
Today, this standard remains in common usage by industry, although it was withdrawn in August 2009 and replaced by ISO 6892-1.
The test pieces are defined according to the shape and type of product tested. Products that may be tested in accordance with this standard include metallic sheets and plates, wire, bar or section, and tubes. Specimens are gripped ensuring that the specimen is aligned axially to minimize bending. The specimen is then strained in tension until failure, and finally the load and strain data are recorded. Results determined typically include yield and proof strengths, ultimate tensile strength, and elongation at fracture.
A typical testing system will include a universal testing machine, with suitable wedge or hydraulic grips, and a clip-on or non-contacting video extensometer to measure strain directly at the specimen.
We recommend that you read and review the standard in full to ensure suitability for the products you wish to test before selecting test equipment.
