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 5655 was prepared by Technical Committee ISO/TC 42, Photography.
This third edition cancels and replaces the second edition (ISO 5655:1993), of which it constitutes a technical
revision based upon ANSI/BAPM IT1.15-1994.
Annex A of this International Standard is for information only.

INTERNATIONAL STANDARD ISO 5655:2000(E)
Photography — Industrial radiographic films (roll and sheet)
and metal intensifying screens — Dimensions
1 Scope
This International Standard specifies the preferred and recognized sizes and cutting dimensions of industrial
radiographic roll and sheet films and metal intensifying screens. It also specifies package markings.
The shaping of the corners of screens is not specified.
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. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
ISO 1:1975, Standard reference temperature for industrial length measurements.
ISO 554:1976, Standard atmospheres for conditioning and/or testing — Specifications.
3 Conditions for measurement of dimensions
The dimensions and tolerances specified in this International Standard apply at the time of manufacture, measured
under atmospheric conditions of (23� 2) °C and (50� 5) % relative humidity, as specified in ISO 554.
Dimensions may be altered by a permanent shrinkage due to aging and by a temporary shrinkage or swell due to
changes in moisture content or temperature. Normally, dimensionally stable polyester base is used for these film
products, and there should be no departure from the specified dimensions by more than 0,05 % greater than the
maximum dimension and� 0,08 % less than the minimum dimension at the time of opening the package.
All measuring-instrument calibrations shall be conducted at a temperature of 20 °C, as specified in ISO 1, and a
relative humidity of 50 %.
4 Films in rolls
4.1 Width of rolls
4.1.1 Preferred widths
Roll widths of preferred sizes shall conform to the values given in Table 1.
4.1.2 General slitting and tolerance rules
For rolls not shown in Table 1, the slitting and tolerance rules shall conform to the values given in Table 2.

For 35 cm and 43 cm nominal, the aim values are obtained by using the nominal values
of 35,6 cm and 43,2 cm, respectively.
4.2 Length of rolls
For rolls of width up to and including 100 mm nominal, the preferred nominal lengths shall be 90 m, 100 m, 150 m
and 305 m.
