Product Description

Low Temperature Brittleness Tester is used to determine the brittleness temperature, specimens are secured to a specimen holder using a torque wrench. The specimen holder is immersed in a bath containing a heat-transfer medium, which has been cooled. The specimens are struck at a specified linear speed and then examined for failures. The brittleness temperature is defined as the temperature at which 50% of the specimens would probably fail.

Test Standards

ISO 974
