ISO 11315-2:1997 Photography -- Projection in indoor rooms -- Part 2: Screen luminance test for still and video projection
standard by International Organization for Standardization, 11/01/1997
More info
Full Description
This part of ISO 11315 specifies the measurement of screen luminance level, as seen by a (seated) viewer for all types of purely optical still projection in darkened projection rooms. Since the optical characteristics of the surface of this screen have a direct bearing on luminance, the screen shall be considered an integral part of the projection system for this part of ISO 11315.
A standardized light-measuring system allows comparison of screen luminance values for different projection systems used alternately in practical use.
