Scope

This standard specifies the principles, methods, and equipment requirements for measuring the thermal deflection rate of thermal bimetallic helical elements. This standard is applicable to the measurement of the thermal deflection rate of thermal bimetallic flat helical elements and straight helical elements, as well as the measurement of the thermal deflection rate of thermal bimetallic elements with a thickness of less than 0.3 mm. This standard is a quality inspection method for determining whether a batch of thermal bimetallic helical elements is acceptable or rejected. This standard helps determine the optimal thickness and length of the helical element material under a certain deflection amount.
