1、 1 Scope This standard specifies the make-up or assembly of leaders and cue marks for 70-, 35-, and 16-mm motion-picture release prints for use in motion-picture theaters and screening rooms. 2 Normative reference The following standard contains provisions which, through reference in this text, cons

2、titute provisions of this standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent edition of the standard listed below.
