The most common tests done on a universal testing machine are tensile tests. Tension tests are performed typically on materials such as film, plastic, metal, textiles etc. to determine it's yield point, modulus of elasticity, strain and breaking force among other properties. Typically on static tests such as these the data is graphed by plotting points of data on whats called a stress/strain (force/displacement) curve.

Most tensile tests are done by following standards such as ASTM, ISO, BS, KS etc. The standards often determine the speed of the test, the shape of the specimen and the properties to measure. For more information on standards check out our information library or our test solutions page.
Samples and grips
Tensile tests are typically done on a standardized shape which helps ensure testing accuracy and comparability universally. Depending on the material or product being tested the tests can be done as is with no preparation requirements.
Some tensile tests require the use of extensometers. Extensometers are measurement devices used to more accurately measure the deformation in the sample. Extensometers come in various shapes with different sensors being used for different applications.
Some tensile tests require the use of an environmental chamber to see the material properties effects of temperature.
