Abstract

Methods are described for measurement of total normal emittance, in air, for temperatures up to 2500°F; for normal spectral reflectance, in air, at low temperature for wavelengths from 0.30 to 25 microns; and in air, at 1000°F, from 1 to 25 microns. Results are given for twenty samples of different materials and the measured total emittances are generally within 5% of values predicted from reflectance measurements.

Reflectances were also measured as a function of angle for wavelengths of the order of 1 micron, to give absorptances as a function of angle of incidence that are useful in the appraisal of solar irradiation.

A spectral emittance unit is described and the preliminary results for samples at 1400°F show general agreement with measured values of spectral reflectance.
