FOREWORD
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO Member Bodies). The work of developing International
Standards is carried out through ISO Technical Committees. Every Member Body interested
in a subject for which a Technical Committee has been set up 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 International Standards by the
ISO Council.
Prior to 1972, the results of the work of the Technical Committees were published as ISO
Recommendations; these documents are now in the process of being transformed into Inter-
national Standards. As part of this process, Technical Committee ISO/TC 55 has reviewed
ISO Recommendation R 1031 and found it suitable for transformation. International Stan-
dard ISO 103 1 therefore replaces ISO Recommendation R 103 1 - 1969.
ISO Recommendation R 103 1 was approved by the Member Bodies of the following countries :
Austria Greece Poland
Belgium Hungary Portugal
Bulgaria India South Africa,
Canada Ireland Rep. of
Czechoslovakia Israel Sweden
Denmark Italy Turkey
Egypt, Arab Rep. of Korea, Rep. of United Kingdom
Finland Netherlands U.S.S.R.
France New Zealand Y ugoslavia
Germany Norway
No Member Body expressed disapproval of the Recommendation.
AVANT-PROPOS
L ’ISO (Organisation Internationale de Normalisation) est une federation mondiale d ’orga-
nismes nationaux de normalisation (Comites Membres ISO). L ’elaboration de Normes
Internationales est confiee aux Comites Techniques ISO. Chaque Comite Membre interesse
par une etude a le droit de faire Partie du Comite Technique correspondant. Les organi-
sations internationales, gouvernementales et non gouvernementales, en liaison avec l ’IS0,
participent egalement aux travaux.
Les Projets de Normes Internationales adoptes par les Comites Techniques sont soumis
aux Comites Membres pour approbation, avant leur acceptation comme Normes Inter-
nationales par le Conseil de I ’ISO.
Avant 1972, les resultats des travaux des Comites Techniques etaient publies comme Recom-
mandations ISO; maintenant, ces documents sont en cours de transformation en Normes
Internationales. Compte tenu de cette procedure, le Comite Technique ISO/TC 55 a examine
la Recommandation ISO/R 1031 et est d ’avis quelle peut, du Point de vue technique,
etre transformee en Norme Internationale. Celle-ci remplace donc la Recommandation
ISO/R 1031 - 1969.
La Recommandation ISO/R 1031 avai t etc approuvee par les Comi tes Membres des pays
suivants :
Afrique du Sud, Finlande Pays-Bas
Rep. d’ France Pologne
Allemagne Gr&ce Portugal
Autriche Hongrie Royaume-Uni
Belgique Inde Suede
Bulgarie Tchecoslovaquie
Irlande
Canada Israel Turquie
Corde, Rep. de U.R.S.S.
Italie
Danemark Norvege Yougoslavie
Egypte, Rep. arabe d’ Nouvelle-Zelande
Aucun Comite Membre n ’avait desapprouve la Recommandation.
