Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national
standards bodies (IS0 member bodies). The work of developing International Standards is car-
ried out through IS0 technical committees. Every member body interested in a subject for which
a technical committee has been authorized 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.
Draft International Standards adopted by the technical committees are circulated to the member
bodies for approval before their acceptance as Interna tional Standards by the IS 10 Council.
International Standard IS0 5/l was developed by Committee ISO/TC 42, Photo-
Technical
graphy, and was circulated to the member bodies in December 1982.
It has been approved by the member bodies of the following countries :
Australia Germany, F.R. Netherlands
Belgium Hungary Poland
Czechoslovakia Italy United Kingdom
Egypt, Arab Rep. of Japan USA
France Mexico USSR
No member body expressed disapproval of the document.
Avant-propos
L’ISO (Organisation internationale de normalisation) est une federation mondiale d’organismes
nationaux de normalisation (comites membres de I’ISO). L’elaboration des Normes internationa-
les est confide aux comites techniques de I’ISO. Chaque comite membre interesse par une etude
a le droit de faire partie du comite technique correspondant. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec I’ISO, participent egalement aux tra-
vaux.
Les projets de Normes internationales adopt& par les comites techniques sont soumis aux comi-
tes membres pour approbation, avant leur acceptation comme Normes internationales par le
Conseil de I’ISO.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national
standards bodies (IS0 member bodies). The work of developing International Standards is car-
ried out through IS0 technical committees. Every member body interested in a subject for which
a technical committee has been authorized 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.
Draft International Standards adopted by the technical committees are circulated to the member
bodies for approval before their acceptance as Interna tional Standards by the IS 10 Council.
International Standard IS0 5/l was developed by Committee ISO/TC 42, Photo-
Technical
graphy, and was circulated to the member bodies in December 1982.
It has been approved by the member bodies of the following countries :
Australia Germany, F.R. Netherlands
Belgium Hungary Poland
Czechoslovakia Italy United Kingdom
Egypt, Arab Rep. of Japan USA
France Mexico USSR
No member body expressed disapproval of the document.
Avant-propos
L’ISO (Organisation internationale de normalisation) est une federation mondiale d’organismes
nationaux de normalisation (comites membres de I’ISO). L’elaboration des Normes internationa-
les est confide aux comites techniques de I’ISO. Chaque comite membre interesse par une etude
a le droit de faire partie du comite technique correspondant. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec I’ISO, participent egalement aux tra-
vaux.
Les projets de Normes internationales adopt& par les comites techniques sont soumis aux comi-
tes membres pour approbation, avant leur acceptation comme Normes internationales par le
Conseil de I’ISO.
La Norme internationale IS0 5/l a et6 elabocee par le comite technique ISO/TC 42, Photo-
