19、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 organizat
20、ions, 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. International Standards are drafted in accordance with the rules given in th
21、e ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. 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
22、the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 7919-5 was prepared jointly by Technical Committee ISO/TC 108,
23、Mechanical vibration and shock, Subcommittee SC 2, Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures, and Technical Committee IEC/TC 4, Hydraulic turbines. The draft was circulated for voting to the national bodies of ISO and IEC separately.
24、 This second edition cancels and replaces the first edition (ISO 7919-5:1997), of which it constitutes a technical revision. Evaluation criteria have been modified, substituting the former four evaluation zones by a more global division of the whole evaluation area into two major ranges, with change
