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.
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.
International Standard ISO 69 was prepared by Technical Committee
ISO/TC 36, Cinematography.
This third edition cancels and replaces the second edition (ISO 69:1990),
clauses 2, A.2 and A.6 of which have been technically revised.
Annex A of this International Standard is for information only.

INTERNATIONAL STANDARD  ISO ISO 69:1998(E)
Cinematography — 16 mm motion-picture and magnetic-film —
Cutting and perforating dimensions
1  Scope
This International Standard specifies the cutting and perforating dimensions for 16 mm motion-picture and magnetic
films with one or two rows of perforations for the following two categories:
a) 16 mm motion-picture and magnetic films;
b) manufacturer-designated 16 mm professional motion-picture camera films with tighter tolerances.
This International Standard applies to safety raw stock film as described in ISO 543.
2  Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.
ISO 543:1990, Photography — Photographic films — Specifications for safety film.
ISO 544:1976, Standard atmospheres for conditioning and/or testing — Specifications.
3  Dimensions
3.1  The dimensions and tolerances shall be as given in table 1 and in the accompanying figures 1 to 4, and apply
to safety raw stock film as described in ISO 543. The dimensions shall apply at the time of cutting and perforating
for film adjusted to a temperature of 23 °C – 1 °C and a relative humidity of (50 – 2) %, which is the recommended
atmosphere for conditioning and/or testing with reduced tolerances specified in ISO 554.
NOTES
1  If required by usage, the manufacturer may indicate other atmospheric conditions which applied to the dimensional control
and testing at the time of cutting and perforating.
2  This International Standard is based on values adopted for film defined as “low-shrinkage”. See annex A, clause A.3 for
definition of “low-shrinkage”.
3.2  The dimensions and tolerances of 16 mm full-coat magnetic materials at the time of cutting and perforating
shall be as specified by dimensions B¢ and L¢ in table 1.
