Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO member bedies). The work of developing lnter-
national Standards is carried out through ISO 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 ISO Council.
International Standard ISO 2834 was developed by Technical Committee ISO/TC 130,

LIS0 (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

correspondant. 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'ISO.
