Equipment structure:
Low-temperature Brittleness Test Chamber HZ-7004 consists of a workbench, a lifting clamp, an impact device, a low temperature thermometer, a cold well containing a freezing medium, and a compressor.

Equipment principle:
Low-temperature Brittleness Test Chamber HZ-7004 pushes the gripper through the main cylinder to make the sample into the freezing medium, and after holding for a certain time, lifts the gripper, then the subcylinder controls the impact process, observes the damage degree of the sample, and determines at least two through trial and error. The lowest temperature at which the sample is not destroyed and the highest temperature at which at least one sample is destroyed. If the difference between the two results is not more than 1 ° C, the test is completed.

Corresponding standard:
GB1682-82, ISO812.
