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).

This document was prepared by Technical Committee ISO/TC 195, Building construction machinery and equipment, Subcommittee SC 1, Machinery and equipment for concrete work.

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.
