Abstract

Four newly developed solar absorber coatings are to be evaluated with the help of thermal cycling and optical characterisation. An initial round robin campaign reveals the need of a standardisation of the calculation procedure of solar absorptance and thermal emittance derived from optical measurements at room temperature. The implementation of a common processing of spectral hemispherical reflectance values enables a reduction of standard deviations to 0.2%, both for solar absorptance and thermal emittance. The calculation procedure proposed within this paper corresponds to DIN EN 22975-3 and enables the verification of measurement reproducibility according to ASTM E 691 – 05.
