Selection of Program for Heat Tests of Objects with Spectral and Selective Properties, Using Radiant Heating Facilities

A technique for selecting a program to control the heating of objects with spectral and selective properties is considered with respect to applications in heat tests of fire-proof materials using radiant heating facilities. It is shown that changing the operation mode of the facility, based on halogen lamps, results in change of the absorption coefficient, which should be taken into consideration for the heating program selection.
