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. 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. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This first edition of ISO 18651 cancels and replaces ISO 18651-1:2011, which has been technically revised.
The main changes are as follows:
— revised ISO 18651-1 to ISO 18651 and eliminated “Part 1”;
— revised a few term definitions and added terms to Clause 3;
— changed term 3.7 “vibration head” to “vibrator assembly” and designated respective component in
Figures A.1 to A.9;
— changed term 3.10 “flexible drive shaft” to “flexible shaft”;
— removed Clause 4 "Structure";
— removed 5.2 "Complementary data for all types of immersion vibrator";
— removed “c) length of the hose-handle m” in 5.3.2;
— modified Figure A.1 a) to replace the section by correct one without electric motor;
— modified the title of Figure A.1 and subfigures a), b);
— deleted Figure A.10 which was not mentioned in the body.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d'approbation requis pour les différents types de documents ISO. Le présent document a
été rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir
www.iso.org/directives).
L’ISO attire l’attention sur le fait que la mise en application du présent document peut entraîner l’utilisation
d’un ou de plusieurs brevets. L’ISO ne prend pas position quant à la preuve, à la validité et à l’applicabilité de
tout droit de propriété revendiqué à cet égard. À la date de publication du présent document, l’ISO n'avait pas
reçu notification qu’un ou plusieurs brevets pouvaient être nécessaires à sa mise en application. Toutefois,
il y a lieu d’avertir les responsables de la mise en application du présent document que des informations
plus récentes sont susceptibles de figurer dans la base de données de brevets, disponible à l'adresse
www.iso.org/brevets. L’ISO ne saurait être tenue pour responsable de ne pas avoir identifié tout ou partie de
tels droits de propriété.
Les appellations commerciales éventuellement mentionnées dans le présent document sont données pour
information, par souci de commodité, à l’intention des utilisateurs et ne sauraient constituer un engagement.
Pour une explication de la nature volontaire des normes, la signification des termes et expressions
spécifiques de l'ISO liés à l'évaluation de la conformité, ou pour toute information au sujet de l'adhésion de
l'ISO aux principes de l’Organisation mondiale du commerce (OMC) concernant les obstacles techniques au
commerce (OTC), voir www.iso.org/avant-propos.
Le présent document a été élaboré par le comité technique ISO/TC 195, Machines et matériels pour la
construction des bâtiments, sous-comité SC 1, Machines et équipements pour la mise en œuvre du béton.
Cette première édition annule et remplace l'ISO 18651-1:2011 qui a fait l’objet d’une révision technique. Les
principales modifications sont les suivantes:
— révision de «ISO 18651-1» en «ISO 18651» et suppression de «- Partie 1»;
— révision de quelques définitions de termes et ajout de termes dans l'Article 3;
— modification de la définition du vibrateur interne hydraulique
— remplacement du terme 3.7 «tête vibrante» par «unité vibrante» et désignation du composant
correspondant dans les Figures A.1 à A.9;
— remplacement du terme 3.10 «arbre de transmission flexible» par «arbre flexible»;
— suppression de l’Article 4, Structure;
— suppression du paragraphe 5.2 «Données complémentaires pour tous les types de vibrateurs internes»;
— suppression de «c) longueur de la tête de puissance m;» dans le paragraphe 5.3.2;
— modification de la Figure A.1 a) pour remplacer la section par une section correcte, sans moteur
électrique;
— modification du titre de la Figure A.1 et des sous figures a), b);
— suppression de la Figure A.10 qui n'était pas mentionnée dans le corps du texte.
