scope:

Specifies the following: - Dimensions of film lengths; - Late nt-image frame numbering; - Latent-image digital bar-codes to identify the film DX number; - Dimensions of daylight-loading film magazines for use with 135-size cameras; - A magazine bar-code that identifies the film's DX number as well as the number of exposures; - Camera auto-sensing areas, which provide an electrically readable encodement of film speed, number of exposures, and recommended exposure latitude for use with appropriately designed cameras; - An information panel on which the film identification, speed, and number of exposures are visible through a window in the back of appropriately designed cameras; - Film pull-out force specification; - Film-spool attachment strength specification. This International Standard is not intended to apply to 'bulk' 35-mm film for reloading into 135-size magazines, nor to the reloadable magazines themselves. Also, this standard does not apply to 135-size film and magazines that are used in single-use camera applications.
