Optical characterisation

Caracterización óptica

We are a reference laboratory in optical characterisation of glazing, surfaces and finishes.

We carry out tests and calculations to determine light, solar and ultraviolet transmittance, reflectance and absorptance and their emissivity.

Tests and Standards

  • EN 410 Glass in building: Determination of luminous and solar characteristics of glazing.
  • ISO 9050 Glass in building: Determination of light transmittance, solar direct transmittance, total solar energy transmittance, ultraviolet transmittance and related glazing factors
  • ASTM E903 Test method for solar absorptance, reflectance and transmittance of materials using integrating spheres
  • BS 8493 Light reflectance value (LRV) of a surface.
  • EN 3363-1 Solar protection devices combined with glazing. Calculation of total solar energy and light transmittance. Part 1: Simplified calculation method and EN 13363-2 Calculation of total solar energy and light transmittance. Part 2: Detailed calculation method.
  • EN 14500 Blinds and shutters. Thermal and visual comfort. Test and calculation methods
  • ASTM C 1371 Standard method for the determination of the emittance of materials near room temperature using portable emissometers.
  • ASTM E 1980 Standard practice for calculating solar reflectance index of horizontal and low-sloped opaque surfaces.
  • En ISO 2813 Paints and varnishes. Determination of gloss value at 20°, 60° and 85°.
  • EN ISO 11664-3:2013 Calorimetry. Part 3: CIE tristimulus values
