Glass in building. Determination of the emissivity included-in-kit b) electrical control equipment whichWhat is this standard about? This document specifies a procedure for determining the emissivity at room temperature of the surfaces of glass and coated glass. The emissivity is necessary for taking into account heat transfer by radiation from surfaces at the standard temperature of 283 K in the determination of the U value and of the total solar transmittance of glazing. The procedure, being based on spectrophotometric regular reflectance measurements
