This standard EN 4593 has been prepared by ASD-STAN, Technical Section Non-metallic materials, with the participation of German experts of the Coatings and Coating Materials Standards Committee (NAB) and the Aerospace Standards Committee (NL). This European Standard specifies the method of test for determining the solar absorptance of paints and varnishes. The test procedure determines the amount of energy reflected by the material in the range of wavelengths at which there is energy from the sun hitting the Earth's surface, and with the aid of a standard solar spectrum it allows a calculation to determine the solar absorptance which can then be used to determine the efficiency of solar heat reflecting paints. This procedure is applicable to products intended for use in aerospace applications.
