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 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 the ISO/lEC Directives, Part 3 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 ISO 8165-2 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 2, Physical, chemical and biochemical methods. Iso 8165 consists of the following parts, under the general title Water quality - Determination of selected monovalentphenols: Part 1: Gas-chromatographic method after enrichment by extraction Part 2: Method by derivatization and gas chromatography Annex A of this part of ISO 8165 is for information only ii
