TEST STANDARD
IEC60068-2-14 Change of temperature with specified rate of change
INTRODUCTION
This chamber is ideally suited for specimen test requiring quick changes of temperature. It can evaluate the failure of thermal mechanical properties of product. Normally the temperature rate is less than 20C/min, which can achieve the real application environment of testing sample by the fast ramp rate.
