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/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Attention is drawn to the possibility that some of the elements of this part of isO 9377 may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 9377-2 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 2, Physical, chemical and biochemical methods. IsO 9377 consists of the following parts, under the general title Water quality - Determination of hydrocarbon oil index: iteo — Part 2: Method using solvent extraction and gas chromatography Annexes A, B and C of this part of iSO 9377 are for information only iv @ ISO 2000 - All rights reserved ISO 9377-2:2000(E) INTERNATIONALSTANDARD Water quality Determination of hydrocarbon oil index - Part 2: Method using solvent extraction and gas chromatography 1 Scope plants and allows the determination of a hydrocarbon oil index in concentrations above O,1 mg/l. The method is not applicable to the quantitative determination of the content of volatile mineral oil. However, on the oil contamination can be derived.
