The work of preparing International Standards is normally carried out through ISOtechnical committees. Each member body i
10、nterested 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. ISOcollaborates closely with the International Electrotechni
11、cal 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 least75% of the member bodies casting a vote. In
12、ternational Standard ISO13359 was prepared by Technical Committe ISO/TC 30, Measurement of fluid flow in closed conduits, Subcommittee SC 5, Velocity-based methods.
