This document covers the determination of the total luminous transmittance, in the visible region of thespectrum, of planar transparent and substantially colourless plastics, using a single-beam photometerwith a specified CIE Standard light source and photodetector. This document cannot be used for plasticswhich contain fluorescent materials.This document is applicable to transparent moulding materials, films and sheets not exceeding 10 mmin thickness.NOTE 1 Total luminous transmittance can also be determined by a double-beam spectrophotometer as inISO 13468-2. This document, however, provides a simple but precise, practical and quick determination. Thismethod is suitable for use not only for analytical purposes but also for quality control.NOTE 2 Substantially colourless plastics include those which are faintly tinted.NOTE 3 Specimens more than 10 mm thick can be measured provided the instrument can accommodate them,but the results might not be comparable with those obtained using specimens less than 10 mm thick.
