Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards institutes (IS0 member bodies). The work of developing Inter-
national 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 662 was developed by Technical Committee ISO/TC 34,
Agricultural food products, and was circulated to the member bodies in January 1979.
It has been approved by the member bodies of the following countries :
Australia India Romania
South Africa, Rep. of
Bulgaria Kenya
Korea, Rep. of Spain
Canada
Cyprus Malaysia Thailand
Mexico Turkey
Czechoslovakia
United Kingdom
Ethiopia Netherlands
New Zealand Yugoslavia
France
Germany, F.R. Poland
Portugal
Hungary
The member body of the following country expressed disapproval of the document on
technical grounds :
Peru
This International Standard has also been approved by the International Union of Pure
and Applied Chemistry (IUPAC).
It cancels and replaces IS0 Recommandations ISO/ 968 and ISO/R 933-1969,
of which it constitutes a technical revision.

Avant-propos
L'ISO (organisation internationale de normalisation) est une fédération mondiale
d'organismes nationaux de normalisation (cornités 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
correspondant. Les organisations internationales, gouvernementales et non gouverne-
J
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'ISO.
La Norme internationale IS0 662 a été élaborée par le comité technique ISO/TC 34,
Produits agricoles alimentaires, et a été soumise aux comités membres en janvier 1979.
Les comités membres des pays suivants l'ont approuvée :
Afrique du Sud, Rép. ci'

Cette Norme internationale a également été approuvée par l'Union internationale de
chimie pure et appliquée (UICPA).
Elle annule et remplace les Recommandations ISO/R 662-1968 et ISO/R 933-1969,
dont elle constitue une révision technique.
