1.1 This International Standard specifies basic technical characteristics for the international exchange of analogue photographic sound test films intended for checking, adjusting and measuring motion-picture projector sound systems and sound reproducing channels of motion-picture installations for monophonic or stereophonic reproduction. 1.2 This International Standard specifies types and technical characteristics of test films made on 35 mm and 16 mm motion-picture films. 1.3 This International Standard includes test films intended for the checking, adjusting and measuring of focusing and azimuth of the scanning beam, scanning beam width and its position relative to the reference edge of the film, uniformity of the scanning beam illumination, level output balance of several motion-picture projectors, frequency response of the sound reproduction channel, and non-uniformity of film travel.
