Measurement of characteristics of A-glass sheet
The thermal and optical properties of the glass sheet were measured according to the following principles and criteria:
1) optical properties:
the measurements are carried out according to European standard ISO 9050 (2003). More specifically, according to the light source D65The light transmission T was measured between 380 and 780 nmLAnd a light reflectance R on one side of the stacked bodyLc。
Measuring the parameter a according to the (L, a, b) colorimetric modelc(stack side in internal reflection).
2) Thermal properties:
by determining the emissivity at normal incidence according to the conditions described in standard ISO10292 (1994), appendix AnTo evaluate the thermal insulation properties of the glass sheet, said emissivity being measured on the inner face of the substrate covered with the stack of layers.
Measurement of light transmittance T for glass sheets equipped with the stackL、a*cReflectivity RLcAnd normal emissivitynValues (in percent).
