1.1 Purpose
It is used to determine the capacity of bearing rapidly changing ambient temperature for component, equipment and other products. The required exposure duration depends on the property of test sample.
1.2 General descriptions for the test
The test samples are exposed to low and high temperature air (or appropriate inert gas) to bear the influence of rapidly changing temperature.
1.3 Description of test equipment
1.3.1 Test chamber
1.3.1.1 Two test chambers shall be prepared, one is low temperature chamber, the other is high temperature chamber, The position two chambers placed shall be able to transfer the test sample from one chamber to the other chamber in specified time. The conversion method may be manual or automatic.
