Thermal Cycling Test Procedure

Thermal cycling ovens are capable of achieving temperature ranges between 60 and 140 c.

Thermal cycling test procedure.

5 1 exposing a specimen to conditions of one directional environmental cycling can increase its moisture content until a decrease in material properties occurs at a specific number of cycles. The transition between temperature extremes occurs very rapidly during thermal shock testing greater than 15 c per minute. Thermal ovens require a hold time at an isotherm to assure all samples achieve the test temperature. Thermal cycling testing assures your equipment meets the necessary standards.

Thermal cycling test is the most important performance test for hot and cold water piping system. Thermal cycling is the test or process of cycling a material or device through two set temperature extremes usually at a somewhat high rate of change of temperature. Thermal cycling test can verify the quality of design of the parts raw materials manufacturing procedure and installation process. Thermal cycling is another term often associated with performing temperature and humidity testing.

It should be noted that temperature cycling may also be referred to as thermal cycling or thermal shock testing. Ovens are limited in speed and high end temperature. The thermal cycling profile will replicate the same path to failure as seen in normal use. Our engineers test for thermal protection and water resistance.

It is defined as an environmental stress test used to evaluate the reliability of the material or the product and to identify any manufacturing defects early by inducing failure. It involves exposing test subjects to a controlled cycle of varied periods of hot cold and wet dry.

The length of exposure time and environmental extremes depend entirely on the type of product and its intended application.

Thermal shock testing also called temperature shock testing or temperature cycling exposes products to alternating low and high air temperatures to accelerate failures caused by repeated temperature variations during normal use conditions. To conduct the test all parts of the piping system will be involved such as pipes fittings joints and welds. Such a test could be inappropriate due to the number of cycles required to cause a decrease in material properties since product performance issues often arise only after many years of exposure.
