Abstract

The band emissivity of material thermal radiation under static heating condition is generally measured by trial-error and manual adjustment method of emissivity set value from radiation thermometer. But, this currently measurement method exists the drawback of time consuming to adjust the set emissivity value of radiation thermometer, which result into the incapacity for measurement under dynamic heating condition. Therefore, a novel method for normal band emissivity measurement deduced from wavelength radiation and sample surface temperatures is proposed based on the equivalent principle of radiation energy received. The experiment results show that it is feasible to apply the new measurement and calculation method for normal band emissivity under both static and dynamic heating conditions.
