Foreword
ISO (the International Organization for Standardization) is a worldwide federation
of national Standards bodies (ISO member bodies). The work of preparing
International 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 Electrotechnical 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.
International Standard ISO 9131 was prepared by Technical Committee
lSO/lC 22, Road vehicles, Sub-Committee SC 23, Mopeds.
Annex A of this International Standard is for information only.

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, gou-
vernementales et non gouvernementales, en liaison avec I’ISO participent
egalement aux travaux. L’ISO collabore etroitement avec Ia Commission electro-
technique internationale (GEI) en ce qui concerne Ia normalisation electrotech-
nique.
Les projets de Normes internationales adoptes par les comites techniques sont
soumis aux comites membres pour vote. Leur publication comme Normes inter-
nationales requiert I’approbation de 75 % au moins des comites membres
votants.
