A UTM or tensile testing machine is also known as a tensiometer.
By means of a loadcell, the change in force is recorded that could indicate a failure or loss of strength of the specimen tested. In combination with the travelled distance of the grips, various mechanical parameters can be quantified.
A tensile testing machine is used to perform testing in accordance with several common ISO, ASTM and automotive standards, e.g. ISO 527, ASTM D412, ASTM F88, ASTM A370 and a diversity of other methods.
