The work of preparing International Standards is normally carried out through ISO technical commitees. 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. 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 ISO4364 was prepared by Technical Committee ISO/TC113, Hydrometricdeterminations,Subcommittee SC6,Sediment transport. This second edition cancels and replaces the first edition (ISO 4364:1977), which has been technically revised. Annex A of this International Standard is for information only. @ISO1997 All rights reserved.
