Standards Content (Sample)

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, govern-
mental 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 IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 3451 /4 was prepared by Technical Committee ISO/TC 61,
Plastics.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.

Avant- propos
L'IÇO (Organisation internationale de normalisation) est une fédération mondiale
d'organismes nationaux de normalisation (comités membres de I'ISO). L'élaboration
des Normes internationales est confiée aux comités techniques de I'ISO. Chaque
comité membre intéressé par une étude a le droit de faire partie du comité technique
créé à cet effet. Les organisations internationales, gouvernementales et non gouverne-
*
mentales, en liaison avec I'ISO participent également aux travaux.
Les projets de Normes internationales adoptés par les comités techniques sont soumis
aux comités membres pour approbation, avant leur acceptation comme Normes inter-
nationales par le Conseil de I'IÇO. Les Normes internationales sont approuvées confor-
I'ISO qui requièrent l'approbation de 75 % au moins des
mément aux procédures de
comités membres votants.
La Norme internationale IS0 3451 /4 a été élaborée par le comité technique ISO/TC 61,
Plastiques.
L'attention des utilisateurs est attirée sur le fait que toutes les Normes internationales
sont de temps en temps soumises à révision et que toute référence faite à une autre
Norme internationale dans le présent document implique qu'il s'agit, sauf indication
contraire, de la dernière édition.
