Abstract
This International Standard specifies basic technical characteristics for the magnetic sound test films for checking, adjusting and measuring sound reproducing channels of dubbing motion-picture installations.
It also specifies types and technical characteristics of magnetic test films made on 35 mm, 17,5 mm and 16 mm motion-picture films.
This International Standard includes test films intended for the checking, adjusting and measuring of
a) inclination angle (azimuth) of the magnetic head gaps;
b) output level balance of multi-channel systems;
c) frequency response of the sound reproduction channel;
d) non-uniformity of film velocity (flutter).
