Methodical Issues of Ensuring Measurements of Thermal Test Parameters

Measurement of the parameters of external thermal impact on the test object and the results of this impact — temperature at control points — have required the development of appropriate methods and technical means. In this case, it has been necessary to take into account the features associated with both the conditions of heating the test object by radiation and its physical properties and the range of change of the recorded values. Below, some methods examined during high-temperature thermal testing of structures using radiation sources have been considered.
