Abstract:

This report of test describes a heat-flux gage calibration system that was developed at the National Bureau of Standards during the 1970s. It is based on a commercial radiant heater incorporating a tungsten lamp and elliptical mirror. A kaledioscope flux redistributor is used to improve the uniformity of the heat flux distribution at the gage surface. The results of recent calibrations for ten heat flux gages are compared with calibrations upplied by the gage manufacturer.
