6.1.1 Standard NF-EN 12898: glass in construction, determination of emissivity
This European standard specifies a procedure for determining the emissivity of glazing at room temperature. This measurement has become essential for determining the thermal transmittance of windows.
The procedure is based on spectrophotometric measurements of reflectance. Unlike the method described at
