Tensile testing is an important test used to determine the best type of material for a particular application. For this test the material is molded to a standardized sample type and loaded into the machine’s grips. The sample is pulled apart by the machine until the tension causes the material to break or be deformed. Tensile testing can give important measurements such as the ultimate tensile strength (the maximum amount of strength a material can take) and the amount of elongation that occurs before breaking. Things to consider before purchasing tensile testing equipment include the type of grip which will dictate the sample shape, the speed range, the machine’s capacity, and what types of material the machine is optimized for.
