Plastics -- Determination of the total luminous transmittance of transparent materials -- Part 1: Single-beam instrument
This standard was last reviewed and confirmed in 2013. Therefore this version remains current.
Deals with the determination of the total luminous transmittance, in the visible region of the spectrum, of planar transparent and substantially colourless plastics, using a single-beam photometer with a specified CIE standard light source and photodetector. Does not apply to plastics which contain fluorescent substances.
