Tensile Stress-Strain, Strength, Modulus and Poisson's Ratio
A universal testing machine (UTM) is used. The test specimen is loaded between the grips of the UTM. A mechanical (contact) extensometer is used to measure axial strain, and a mechanical (contact) extensometer for transverse strain. For soft materials, video (non-contact) equipment are used. The specimen is stretched at a constant speed while load and strain are recorded.
NOTE: speeds below 1 mm/min are subject to a surcharge due to long test duration.
The speed of testing is specified by the relevant standard; measurements at speeds slower than 1 mm/min may be assessed an additional charge if excessive instrument time is required.
