Design, planning and manufacturing professionals must make careful decisions about who they select to support their business processes. Here at the Institute of Spring Technology we fully understand this and pride ourselves on our broad spectrum of capabilities to support the spring industry. There’s sometimes a misconception that we are just a trade and members association, when actually, the Institute of Spring Technology is an internationally recognised and ISO 17025 accredited test house.

IST – “the home of the everything spring” is a centre of excellence offering a comprehensive range of specialist mechanical tests for all types of springs and non-spring components at our test laboratories located in Sheffield. Our extensive static and fatigue testing laboratories allow testing of many spring types, in a wide range of materials and sizes. Our highly experienced staff have access to state-of-the-art facilities for metallurgical analysis. In addition, IST’s unique facilities can be used on a sub-contact basis for component development to assist the introduction of new and improved products. There are many different types of testing that spring industry professionals require, and independent spring testing is the only way to have complete confidence in your design.

One of the most popular tests IST conduct is fatigue testing of compression, extension and torsion springs. This is the only way to validate predicted life expectancy. We undertake fatigue tests on a daily basis for customers wanting assurance that their springs will last the distance. It can take as little as three days to test a spring up to ten million cycles (this is usually regarded as the point at which the spring can be said to have infinite life) but longer testing is also an option.

It is vital to fully understand the problem, and the role that the spring is trying to perform and that’s why we offer a full problem-solving consultancy, looking at all aspects and your uses for the springs. We work daily with customers from a vast range of industries, especially;


  • Rail industry  
  • Aerospace sector
  • Automotive manufacturing sector
  • Medical applications
  • Oil & Gas and Energy Applications 


We know these applications must encompass the best quality possible, meaning any springs must be designed by an experienced professional and then tested to the ISO 17025 accreditation standards, mitigating any unnecessary spring component failure, which can be dangerous and unlawful.

Institute of Spring Technology training

Upon the receipt of spring samples, and using a range of IST testing techniques, we can test and pinpoint the root cause of any failures.  We offer a competitively priced service and provide no-obligation quotations in 5 days (or even 2 days if our priority service is requested). Once testing is complete, a detailed report is produced including certifications and photographic evidence. This can then be discussed with the customer to make sure they are completely happy before the final report is emailed out Giving you confidence that you have done everything possible to validate your springs.

Once your immediate problem is solved, it’s often advised to have some sort of formal training to help understand and improve your processes going forward, and for that we offer practical spring design courses at our centre of excellence in Sheffield.

The upcoming spring design courses are:
14th & 15th May 2019
19th & 20th September 2019
10th & 11th November 2019

We also have the capacity to travel to wherever you are – this can be particularly useful if you want to train a significant number of people or want a more tailored course, so please do not hesitate to get in touch if IST can help you.
