PUBLISH DATE 1997
ISO 4834:1997

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:

  • inclination angle (azimuth) of the magnetic head gaps;
  • output level balance of multi-channel systems;
  • frequency response of the sound reproduction channel;
  • non-uniformity of film velocity (flutter).
