Tensile tests produce a stress-strain diagram, which is used to determine tensile modulus.
The data is often used to specify a material, to design parts to withstand application force and as a quality control check of materials. Specimens are placed in the grips of the Instron at a specified grip separation and pulled until failure. An extensometer is attached to test specimen to determine elongation and tensile modulus. I tensile bar. The most common specimen for ISO 527 is the ISO 3167 Type 1A multipurpose specimen .
