This test method is sensitive to transparencies that vary in transmissivity as a function of wavelength.<\/p>\n<p id=\"s00003\">1.2 Since the transmissivity (or transmission coefficient) is a ratio of two radiance values, it has no units. The units of radiance recorded in the intermediate steps of this test method are not critical; any recognized units of radiance (for example, watts\/m <sup>2<\/sup> -str) may be used, as long as it is consistent.<\/p>\n<p id=\"s00004\">1.3 <span class=\"italic\">This standard does not purport to address all of the safety concerns, if any, associated with its use.
