Foreword- - - - -
IS0 (the International Organization for Standardization) is a worldwide federation
of national standards bodies (IS0 member bodies). The work of preparing Inter-
national 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 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 1 to International Standard IS0 472:1988 was prepared by Technical
Committee ISO/rC 61, Plastics, Sub-Committee SC 1, Terminology.

Avant-propos
L ’ISO (Organisation internationale de normalisation) est une federation mondiale
3organismes nationaux de normalisation (comites membres de I ’ISO). L ’elabo-
ration des Normes internationales est en general confide aux cornit& techniques
de I ’ISO. Chaque comite membre interesse par une etude a le droit de faire par-tie
du comite technique tree 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 la Commission electrotechnique
internationale (CEI) en ce qui concerne la normalisation electrotechnique.
Les projets de Normes internationales adopt& par les comites techniques sont
soumis aux comites membres pour vote. Leur publication comme Normes
internationales requiet-t I ’approbation de 75 % au moins des comites membres
votants.
L ’Amendement 2 a la Norme internationale IS0 472:1988 a ete elabore par le
comite technique lSO/rC 1, Plastiques, sous-comite SC 1, Terminologie.
