ABSTRACT	In this paper we propose a new technique for the measurement of high temperature emissivity. The method employed here is based on the moving specimen method, and the new technique applied to graphite specimens in several states of surface roughness. We observed that emissivity depends on the roughness of the surface and is influenced by the time constant of the emissivity sensor
