Thermal Shock Resistance Analysis

Thermal Shock Unit


Thermal Shock as a Concept

A product or piece of equipment may be subject to extreme weather conditions during its life cycle. Because of differing thermal properties between different materials, products made of multiple substances will expand and contract at different rates when exposed to heat and cold. Therefore, exposure to large variations in temperature over a short period of time may weaken a product’s structural integrity; this can lead to cracks, chipping, and ultimately failure. To find out what their products can withstand, manufacturers send samples to testing companies like Applied Technical Services, where they undergo Thermal Shock Testing.

Scanning for Resistance

Analysis of Thermal Shock resistance happens in the lab much the same way that it happens in a live-use scenario; the test material is exposed to rapidly changing ambient temperatures. ATS’ technicians will subject the test material to a number of pre-determined temperature cycles, and then analyze whether any failure occurred in the external structure or an internal component. Depending on the results, clients may choose to substitute some of the product’s materials with sturdier stuff to increase its toughness and tensile strength.

Our Equipment

The dual-chambered thermal shock unit features a moving basket that carries the sample from the hot chamber to the cold chamber, allowing for a rapid temperature change. Our unit can produce temperatures between -60°C and 170°C to simulate condition changes as drastic and unforgiving as a client may require that their product endure.

The method varies slightly according to the requirements of the test material. Although a client may request we test their sample to a particular standard, most often client specifications will determine the parameters of the test – the maximum and minimum temperatures, how quickly the change occurs, and how many cycles of change the test sample will be exposed to.

ATS and Weathering Tests

ATS has continually provided unparalleled testing, engineering consulting, and inspection services to clients from many industries for over 50 years. Our environmental testing lab is staffed with specialists in their field, well equipped to handle client needs of any scope. These technicians’ expertise in performing the method and access to our powerful equipment allows ATS to return accurate, relevant results more quickly than other testing labs.

Whether for quality control or failure analysis, whether for the electrical industry or the military, ATS can help you determine your product’s resistance to Thermal Shock.
