Tensile Testing
Tensile Testing Of Metallic Materials
概要： Tensile testing of metallic materials is specified according to European EN 10002 standard. In this article the terms, definitions and designation for tensile test made at ambient temperature is described. The test involves straining a test piece in tension, generally to fracture, for the purpose of determining mechanical properties.
Tensile testing of metallic materials is specified according to European EN 10002 standard. This standards consists of five parts:
• EN 10002-1 - Method of testing at ambient temperature
• EN 10002-2 - Verification of the force measuring system of the tensile testing machine
• EN 10002-3- Calibration of force proving instruments used for the verification of uniaxial testing machines
• EN 10002-4 - Verification of extensometers used in uniaxial testing
• EN 10002-5 - Method of testing at elevated temperatures
In this article the terms, definitions and designation for tensile test made at ambient temperature is described. The test involves straining a test piece in tension, generally to fracture, for the purpose of determining mechanical properties.
Terms and definitions
For the purpose of this European Standard, the following terms and definitions apply:
• gauge length (L) - length of the cylindrical or prismatic portion of the test piece on which elongation is measured. In particular, a distinction is made between: o original gauge length (Lo) - gauge length before application of force o final gauge length (Lu) - gauge length after rupture of the test piece o parallel length (Lc) - parallel portion of the reduced section of the test piece
• elongation - increase in the original gauge length (Lo) at any moment during the test
• percentage elongation - elongation expressed as a percentage of the original gauge length (Lo)
• percentage permanent elongation - increase in the original gauge length of a test piece after removal of a specified stress, expressed as a percentage of the
