Thermal shock testing

Thermal shock testing

Thermal shock testing exposes products to alternating low and high temperatures to accelerate failures caused by temperature cycles or thermal shocks during normal use. The transition between temperature extremes occurs very rapidly, greater than 15 °C per minute.

Equipment with single or multiple chambers is typically used to perform thermal shock testing. When using single chamber thermal shock equipment, the products remain in one chamber and the chamber air temperature is rapidly cooled and heated. Some equipment uses separate hot and cold chambers with an elevator mechanism that transports the products between two or more chambers.

Glass containers can be sensitive to sudden changes in temperature. So this kind of product is not suitable for thermal shock testing.

Thermal shock occurs when a thermal gradient causes different parts of an object to expand by different amounts. This differential expansion can be understood in terms of stress or of strain, equivalently. At some point, this stress can exceed the strength of the material, causing a crack to form. If nothing stops this crack from propagating through the material, it will cause the object's structure to fail.

How to apply for thermal shock testing?

The following is the simple process for thermal shock testing in our laboratory：

1、Provide our lab your product images and product manuals.

2、Confirm the test standard by both side.

3、Quotation.

4、Fill in the test application form(Our company will provide the application form).

5、Send test samples to our company.

6、Sign the contract and pay.

7、Start testing
