Tensile & Pull Testing Equipment

Tensile testing involves pulling a sample apart until it fails and then measuring the amount of effort involved.

It’s a broad term that refers to all types of force and materials testing applications that follow this process. 

There are many types of test procedures and applications that fall under the umbrella of tensile testing. These include: pull testing, adhesion testing, ductility testing, elastic limit testing, stress testing, and tear testing.

Rather than referring to a single type of test, it’s a catch-all phrase that collates a large group of similar, but unique, applications for testing the physical properties of a sample. Some of these properties include: ultimate tensile strength, break strength, stress, strain and elongation.

Talk to us if you need to carry out a test of this type. We can take you through the pros and cons of each and help you to choose the right approach and the correct technology. 


These days most products and materials are subjected to some type of tensile test for a variety of quality control or R&D purposes. For example, there are many different international standards specific to a particular material type (steelrubber, plastic, aluminum) or a particular industry (aerospaceautomotiveconstruction)

Common properties measured during a tensile test include;

  • Ultimate tensile strength
  • Breaking strength
  • Maximum elongation
  • Reduction in area
From these measurements the following properties can also be determined;
  • Young’s modulus
  • Poisson’s ratio
  • Yield strength
  • Strain-hardening characteristics

Modern Universal Test Machines (UTM’s)

are one of the primary tools used to perform tensile testing applications. They give the user a highly accurate measurement tool that can produce insightful, repeatable test data.


United Testing Systems, our global manufacturer of materials testing equipment, has been manufacturing Universal Test Machines for over 50 years. They are available in many shapes, sizes and capacities in order to meet, or exceed, virtually all international requirements.
