Specifies the following: film length dimensions, latent-image numbering and digital bar-codes identifying film DX number, pull-out force specification, film-spool attachement strength specification and many more.

This International Standard specifies the following:

• dimensions of film lengths;

• latent-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 used 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.
