Materials, thin: Light transmission (NT BUILD 296)

NT BUILD 296

  • This NORDTEST method describes an accurate method to determine the UV and visible light transmittance properties of thin materials in sheet form as a function of wave-length. This method takes into account the light absorbing and scattering effect of pigments in the actual test materials as well as of the reinforcing material in composites, so that light transmittance through materials like coatings, plastics, glass etc. can be measured with a relatively simple apparatus. The effect of UV-protecting additives can, for example, be studied.
