1 This International Standard specifies the screen luminance level and chromaticity, as seen by a seated viewer, for theatrical projection of 70 mm, 35 mm and 16 mm motion-picture prints at 24 frames per second in indoor theatres and review rooms used in judging the quality of prints for inter-national distribution.
For the purposes of this International Standard, the term "screen" is the screen-picture area appropri-ate to the film format and projection system in use.
2 It is also recommended that this International Standard be followed for non-theatrical presentation of 70 mm, 35 mm and 16 mm motion-picture prints intended for projection at 24 frames per second.
