18、O (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 co
19、mmittee 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 electro
20、technical standardization. International Standards are drafted in accordance with the rules given in the 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 me
21、mber bodies for voting. Publication as an International Standard requires approval by at least 75 % of 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 identif
22、ying any or all such patent rights. ISO 772 was prepared by Technical Committee ISO/TC 113, Hydrometry. This fifth edition cancels and replaces the fourth edition (ISO 772:1996), which has been technically revised. It incorporates the Amendments ISO 772:1996/Amd.1:2002 and ISO 772:1996/Amd.2:2004. A

30、discard any term or symbol with differing meanings in different countries, or for different people, or for the same person at different times, and to replace that term or symbol by one which has an unequivocal meaning; c) to exclude terms which are self-evident. As far as possible terms in existing
31、International Standards have been included; however, these terms may be the subject of future amendments. Note that similar or identical terms may have separate definitions under the different categories. It is recognized that it is not possible to produce a complete set of definitions which will be
32、 universally acceptable, but it is hoped that the definitions provided and the symbols used will find widespread acceptance and that their use will lead to better understanding of the practice of hydrometric determinations.

34、avoir une signification diffrente selon les pays, les personnes ou les contextes et le remplacer par un terme ou symbole non quivoque; c) exclure les termes dont la signification est vidente. Dans la mesure du possible, les termes figurant dans des Normes internationales existantes sont inclus; tout
