It includes medical hard-copy imaging films in the form of sheets, such as laser films and video. This International Standard also includes information regarding the appropriate marking of these products, and special attention is given to cassettes/screens/films used for mammography. This International Standard does not include films in roll format (see informative annex A). 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply.
