FOREWORD
IS0 (the International Organization for Standardization) is a worldwide federation
of national standards institutes (IS0 member bodies). The work of developing
International Standards is carried out through IS0 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 IS0 Council.
International Standard IS0 4065 was developed by Technical Committee
ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, and was
circulated to the member bodies in June 1976.
It has been approved by the member bodies of the following countries :
Australia Ireland Portugal
Belgium
Israel Romania
Chile Italy Spain
Denmark Japan Sweden
Finland Korea, Rep. of Switzerland
France Mexico Turkey
Germany New Zealand U.S.A.
India Poland
The member bodies of the following countries expressed disapproval of the
document on technical grounds :

AVANT-PROPOS
L'ISO (Organisation internationale de normalisation) est une fédération mondiale
d'organismes nationaux de normalisation (comités membresde 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
correspondant. Les organisations internationales, gouvernementales et non
gouvernementales, 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 internationales par le Conseil de I'ISO.
La Norme internationale IS0 4065 a été élaborée par le comité technique
ISO/TC 138, Tubes, raccords et robinetterie en matières plastiques pour le trans-
port des fluides, et a été soumise aux comités membres en juin 1976.
Les comités membres des pays suivants l'ont approuvée :
Allemagne France Pologne
Australie Inde Portugal
Belgique Irlande Roumanie
Chili Israël Suède
Corée, Rép. de Italie Suisse
