Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 4090 was prepared by Technical Committee ISO/TC 42, Photography.
This third edition cancels and replaces the second edition (ISO 4090:1991) which has been technically revised.
Annexes B and E form a normative part of this International Standard. Annexes A, C, D and F to I are for
information only.
ISO 4090:2001(E)
Introduction
This International Standard is based on a combination and revision of the following five documents:
� ANSI/NAPM ITI. 49-1995, Photography (Films) — Medical radiographic cassettes/screens/films — Dimensions
and specifications
� IEC 60406:1997, Cassettes for medical X-ray diagnosis — Radiographic cassettes and mammographic
cassettes
� IEC 60658:1979, Radiographic intensifying screens for medical use — Dimensions
� ISO WD1/4090, Photography — Film Dimensions — Medical radiography
� ISO WD2/15264, Photography — Medical hard copy imaging film — Dimensions and specifications
The aim of this International Standard is to bring together all standardized information about dimensions and
related specifications of photographic materials in the form of sheets and related products (screens and cassettes);
all of which are intended for use in medical radiography. The worldwide community using radiographic equipment
will benefit by having all this information in a single text.
This text of this International Standard is not intended to change the contents of the aforementioned documents,
but only to bring them together and to resolve the discordance existing between the different standards or standard
projects. The existence of a single International Standard for sheet films and related products will resolve existing
differences by converting inch sizes to metric sizes.
Inch nominal sizes and inch dimensions are not found in this International Standard. Informative annex F describes
the transition from inch to metric dimensions for the reader. Conversion to metric specifications has resulted in a
potentially confusing situation. Use of the same nominal dimension (20� 40 and 20� 25, for example) might imply
to the reader that the aims and tolerances should be identical. In some cases, where one size is of inch origin and
the other is of metric origin, this is not true. Therefore, TC 42 agreed that it would be best to separate tables into
sizes of metric origin versus sizes of inch origin.
By combining the existing documents and the dimensional tables, the reader can now easily compare sizes of
films, screens and cassettes — all in a glance. Combination has also facilitated a significant comparison of
preferred and recognized sizes, as well as a reconciliation of whether films and screens properly fit inside their
corresponding cassettes. This comparison has resulted in a significant improvement in the agreement between
sizes, as well as component “fit”.
This International Standard refers to mammography cassettes as either preferred sizes or recognized sizes. All
new mammography cassettes must conform to the dimensions given as “preferred”. The dimensions given for
recognized sizes are listed in order to inform the reader regarding an older style of mammography cassettes.
Although the older style cassettes are no longer preferred (no longer the industry standard), use of this style
throughout the world is expected to continue for some time. So, they are listed here as “recognized” only.
Medical radiographic films in roll form are not a part of this International Standard. Use of roll films appears well
established and stable, but does not justify a new, stand-alone standard. In order to assist the reader, information
regarding roll films is listed in informative annex A.
Annexes G, H and I provide information on the dimensional stability of film, quantity packaging and sizes of inch
origin (film dimension exceptions), respectively.
