Thermal Shock Resistance Test Method

Thermal Shock Resistance Test Method

Thermal shock is a sort of structural trauma that can occur to objects as a result of extreme temperature changes. It happens when the tensile strength of the surface material is overcome by strain brought on by the object’s surface expanding or contracting at a different pace than its internal components. The integrity of the product could be compromised by releasing that stress.

The thermal shock resistance test is performed by placing the test article in a unit designed to induce thermal shock by subjecting sample materials to rapidly changing temperatures for a predetermined number of cycles. The unit has a moving basket that allows test subjects to be quickly moved between its two chambers, one hot and one cold. The equipment can generate temperatures ranging from -60°C to 170°C, subjecting the sample to as harsh conditions as the client requires their product to withstand.

Individual product needs will dictate the temperature range and number of cycles applied to the sample, unless the client requests that the test is performed to an existing standard.
