Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0 ’
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. IS0
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 IS0 13450 was prepared by Technical Committee
lSO/TC 42, Photography.
This first edition of IS0 13450 cancels and replaces IS0 7374:1988, which
dealt with dimensions and format of 1 IO-size film and backing paper,
IS0 7330:1987, which dealt with location and dimensions of 11 O-size film
exposure and film identification notches, and IS0 7261 :I 987, which dealt
with 11 O-size cartridge dimensions.
Annexes A, B and C of this International Standard are for information only.
