    Abstract

    Current interest in the measurement of infrared heat emission and absorption of structural materials is discussed. Distinctions between the emission characteristics of materials in the visible and heat radiation regions of the spectrum are made. The terminology of radiation exchange is reviewed from the standpoint of simplicity and usefulness in a standardized test suitable for use with structural materials as non-incandescent temperature radiators. Basic laws of radiation exchange are briefly reviewed. On the basis of the foregoing considerations, the plan of an apparatus construction for surface emittance measurement in the 0 to 300 F range is described.
