What are the effect of Thermal Shock Testing?

Temperature Shock Testing is another name for thermal shock testing. During this testing, products are subjected to alternating low and high temperatures in order to accelerate failures induced by repetitive temperature fluctuations in everyday use.

Thermal shock testing lab are frequently employed for reliability testing because they can successfully imitate identical stress conditions that may occur throughout the course of a products life cycle but in a much shorter and accelerated time frame. The testing results can also be used to pinpoint places where a product could be redesigned to eliminate flaws that could result in product failure and costly warranty rework or recalls.

Why is testing necessary?

With lab-controlled, reproducible simulated temperature change cycles, failure analysis is possible. This test is required by some standards, but it can also be used to help with quality assurance when unexpected temperature fluctuations may occur in the intended end environment of use for the product.

What is the Process of Thermal Shock Testing?

The device under test (DUT) is placed inside a basket that automatically moves between hot and cold zones within seconds to achieve a quick temperature change. An air-to-air or liquid-to-liquid system can control the temperature of these zones.

The Thermal Shock Test can be carried out in one of two ways: by linking two climatic rooms with different temperatures using an elevator that transfers the material from one environment to another, or by rapidly changing the temperature inside a single climatic chamber.

The following are some of the most common issues that might arise as a result of thermal shock exposure.

  • Glass vials and optical material shatter.

  • The slackening or binding of moving elements.

  • Component deformation or fracture.

  • Surface coatings cracking.

  • Sealed chambers leaking.

  • Insulation protection has failed.

  • Differential contraction or expansion rates of various materials, as well as induced strain rates.
