Design of glass panes is covered by prEN 16612 (see 6). 5.3 Designation of clear alumino silicate glass 5.3.1 General An alumino silicate glass product is designated as clear alumino silicate glass when it is not tinted and when the light transmittance of the glass m

47、aterial, unmodified by the possible presence of a coating or surface roughness complies with 5.3.2 and 5.3.3. In order to measure the light transmittance characteristics of glass, to determine whether it can be designated as a clear glass, it is necessary, in some cases, to carry out a pre-treatment

48、: coatings on smooth surfaces have to be eliminated, without modifying the thickness of the glass substrate; rough surfaces, with or without coatings, have to be eliminated by smoothing and polishing. The thickness of the glass will be modified by this process. The light transmittance of the glass s

49、ubstrate shall be measured with its surfaces in a polished condition. DIN EN 15681-1:2016-06 EN 15681-1:2016 (E) 8 NOTE The light transmittance values given in 5.3.2 and 5.3.3 are not suitable for design. They are values used only for the designation of clear glass and exclude the effects of coatings and of surface roughness. The values of light transmittance used for design can be obtained from the glass manufacture
