Abstract

The paper deals with the issue of temperature dependence of emissivity in reference paints for surface homogenization during non-contact temperature measurement using infrared camera. Two different paints for high-temperature applications are under investigation. Emissivity is measured with a FLIR E95 infrared camera using procedures according to ČSN EN ISO 18434-1 standard. The obtained results are important especially for practical applications in which it is necessary to quantitatively measure the variable surface temperature on objects for which the homogeneity of the surface cannot be unequivocally guaranteed.
