Foreword
ISO (the International Organization for Standardization) is a worldwide federation
of national Standards bodies (ISO member bodies). The work of preparing Inter-
national Standards is normally carried out through ISO technical committees.
Esch 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 Electro-
technical 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.
Amendment 4 to International Standard ISO 472:1988 was prepared by Technical
Committee lSO/rC 61, Hastics, Sub-Committee SC 1, Terminology.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une federation mondiale
d’organismes nationaux de normalisation (comites membres de I’ISO). L’elabo-
ration des Normes internationales est en general confiee aux comites techniques
de I’ISO. Chaque comite membre interesse par une etude a Ie droit de faire Partie
du comite technique cr& a cet effet. Les organisations internationales, gouverne-
mentales et non gouvernementales, en liaison avec I’ISO participent egalement
aux travaux. L’ISO collabore etroitement avec Ia Commission electrotechnique
internationale (GEI) en ce qui concerne Ia normalisation electrotechnique.
Les projets de Normes internationales adoptes par les comites techniques sont
soumis aux comites membres pour vote. Leur publication comme Normes
internationales requiert I’approbation de 75 % au moins des comites membres
I votants.
