(Superseding IS 12018 : 1986)

Reaffirmed 2022

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 8622 : 1998 ‘Cinematography - Magnetic sound records on 70 mm motion-picture release prints with magnetic stripes - A-chain reproduction characteristics’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Photography and Cinematography Equipment Sectional Committee and approval of the Mechanical Engineering Division Council.

This standard supersedes IS 12018:1986 ‘Specification for A-chain reproduction characteristics of magnetic sound records on 35 mm and 70 mm striped prints’, which was based on ISO/DIS 8622 ‘Cinematography - Magnetic sound records on 35 mm and 70 mm motion-picture release prints with magnetic stripe - A-chain reproduction characteristics’.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear, referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards the current practice is to use a point (.) as the decimal marker.
