Cyclic testing involves repeated testing of a product to confirm its reliability and simulate real-world conditions. It can demonstrate a product’s performance over time and under stress, and is important for reliability testing. Testing can be done in-house or at a materials testing facility.
A cyclic test is a type of test in which a product, material or object of interest is subjected to repeated tests, instead of a single test cycle. The goal of such testing is to confirm that the product will function reliably and to have the opportunity to simulate many different real-world conditions. Cyclic testing is performed with the assistance of a variety of test equipment. Test equipment manufacturers may offer a range of cycling test equipment, along with other types of equipment that can be used in a cycling test.
In essence, cyclic testing involves testing and re-testing, to double-check the product’s performance at various intervals. This gives you a better idea of how the product performs in the real world, as most products are used over a long period of time. A cycling test can demonstrate not only a product’s capability when new, but also performance over time, looking at how issues such as wear and corrosion interact with the product over its lifetime.
During cyclical testing a variety of stress tests can be used to try and push a product to its limits. A cyclic test can also include simulated conditions such as hot, humid, sandy or salty work environments. Testers can think about the conditions under which the product is likely to be used to think about possible test scenarios that could provide useful insights when people evaluate how the product might perform in the real world.
Reliability testing can be important for many products and components. A cyclic load test, for example, subjects a test material to load cycles that will show how it performs over time in a variety of environments. This information can be invaluable for things like the components used in building a bridge. While it’s helpful to know that such components don’t fail immediately, it’s also helpful to know how far they can be pushed before they start to fail. This information can be used to troubleshoot issues such as maintenance scheduling.
Products can be sent to a materials testing facility for a cyclic test in a laboratory that specializes in this type of testing and materials testing in general. It is also possible to perform such tests in an in-house laboratory. Many large companies that engage in complex engineering do material tests in their own laboratories during product development, although they may send products later to demonstrate a good faith interest in getting a neutral third party to evaluate the safety of their products. .
