  • Page 31: Why Is Reflected Appearance Important

    The Gloss Unit (GU) is defined in international standards including ISO 2813 and ASTM D523. It is determined by the amount of reflected light from a glass standard of known refractive index. Calibration tiles supplied with Rhopoint instruments are traceable to master glass standards held at NIST (USA).
  • Page 32 The measurement angles most commonly used for gloss are 20°, 60° and 85°.  The most appropriate angle should be selected dependent on the glossiness of the sample surface.  Using the correct measurement geometry increases resolution and improves the correlation of results with human perception of quality. Graph showing 13 painted panels visually assessed and ranked for gloss, the measured values show 85°...

  • Page 33: Reflectance

    % Reflectance Materials having a high refractive index such as clear plastics and varnishes can typically have measurement values that exceed 100GU due to multiple reflections occurring within the material. Highly reflective metals can also produce gloss values up to 2000GU. In these cases, it is common not to report values in GU but to express them in terms of percentage Reflectance.
  • Page 34 Haze* Haze describes the milky halo or bloom seen on the surface of high gloss surfaces. Surface haze can be problematic in most coating applications including automotive manufacture, powder coatings and other high gloss coatings. It can be attributed to a number of causes including incompatible materials in a formulation, poor dispersion and problems encountered during drying/curing/stoving.

  • Page 35: Measuring Haze With The Novo-Gloss 20/60/85 With Haze

    Measuring Haze with the Novo-Gloss 20/60/85 with Haze Gloss Haze values can be calculated using two ASTM test methods – ASTM E430 – using defined angular tolerances around the 20 degree specular angle ASTM D4039 – using the calculated difference between measured gloss values at 20 and 60 degrees (H = G –...
  • Page 36 Corrected haze measurement on metallic coatings For non metallic surfaces, the diffuse component is lambertian- it is equal in amplitude at all angles in relation to the sample surface. Conventional gloss-hazemeters measure diffuse reflection using a luminosity sensor positioned away from the gloss angle. Luminosity is subtracted from the haze signal allowing non metallic surfaces measured independent of their colour.
