Over deze norm
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.
