This paper deals with the radiative calibration aspects
of high heat flux sensors using blackbody radiation.
Several heat flux sensors were calibrated up to 50kW/m2
in the last two years using a 25 mm diameter aperture
variable temperature blackbody and a reference room
temperature electrical substitution radiometer. Tests
carried out on a typical Schmidt-Boelter heat flux
sensor showed long term repeatability of calibration
within +-0.6%. Plans for extending the present
calibration capability to 100 kW/m2 are discussed.
