Tensile testing is a broad term that refers to all types of force and materials testing applications that involve using a universal test machine to pull on a sample until it fails. There are many different types of test procedures and applications which fall under the larger umbrella of tensile testing. Some of these are adhesion testing, ductility testing, elastic limit testing, stress testing, and tear testing. Therefore, rather than referring to a single type of test, tensile testing refers to a large group of similar but unique applications that test materials for certain physical properties. Some of these properties are ultimate tensile strength, break strength, stress, strain and elongation. When considering what equipment to purchase a user must specify which type of tensile test they are performing to ensure the proper equipment is purchased.
