Newly we measure optical properties according to ASTM E1980, ASTM E903, ASTM E408

18.12.2014
Our optical properties laboratory is now able to provide measurements of the optical properties according to ASTM standards. Our measurements and calculations meet the following standards:
  • AASTM E1980 - calculation of SRI (Solar Reflectance Index)
  • ASTM E903 – measurement of solar absorptivity, reflectivity and transmissivity
  • ASTM E408 – measurement of total emissivity
