This International Standard specifies the dimensions for 8 mm Type S motion-picture projection reels/spools of 75 to 312 mm diameter (with the exception of the 75 mm Type No. 7) that are interchangeable on all types of reel-to-reel projection equipment. NOTE - The No. 7 reel (75 mm), although temporarily recognized, will be superseded by that specified in ISO 6033. lt is recommended that new projection equipment and reel/spool manufacturing capacity should comply with the requirements of ISO 6033.
