Evaluation of the total emissivity coefficient of solid materials and coatings at low temperatures

A version of the calorimetric method (comprising two coaxial cylinders with the internal cylinder containing a specimen raised to a temperature higher than that of the surrounding sheath) which has been previously used only for high temperature measurement was successfully applied at low temperatures.
The error in measuring with the laboratory equipment described above and based on the calorimetric method does not exceed ±8%.
