Thermal Shock Testing Equipment at Keystone Compliance

Keystone Compliance offers thermal shock testing within any of our environmental chambers. Keystone Compliance will soon be adding automated temperature shock equipment.

Thermal Shock Testing Overview

Thermal shock testing, per MIL-STD 810 Method 516.5, is conducted to determine if equipment can withstand sudden changes in the temperature of the surrounding atmosphere without experiencing physical damage or deterioration in performance. As a result of exposure to sudden temperature changes, operation of the test items may be affected either temporarily or permanently.

Thermal shock testing has two objectives; 1) to determine if the test item can satisfy its performance requirements after exposure to sudden changes in temperature of the surrounding atmosphere and 2) to determine if the test item can be safely operate following exposure to the sudden change in temperature of the surrounding atmosphere.

Examples of problems that could occur as a result of exposure to sudden changes in temperature include but are not limited to:

  • Shattering of glass, vials and optical equipment
  • Binding or slackening of moving parts
  • Separation of constituents
  • Changes in electronic components
  • Electronic or mechanical failures due to rapid water or frost formation
  • Cracking of solid pellets or grains in explosives
  • Differential contraction or expansion of dissimilar materials
  • Deformation or fracture of components
  • Cracking of surface coatings
  • Leaking of sealed compartments
