The work of preparing International Standards is normally carried out through ISO technical comm
8、ittees. 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
9、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 2. The main task of technical committees is to prepare International Standards. Draft Internation
10、al 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.

16、a, with the use of more potent gas turbines and single shaft combined cycle gas turbines has made necessary the update of the classification of fluids for turbines. In addition, regulations in some countries are requiring the use of environmentally acceptable lubricants for the lubrication of hydro-
17、turbines. The new classification includes a) new types of gas turbine oils, including synthetic products; b) new types of oils for single-shaft combined-cycle gas turbines (i.e. turbines where the same lubricant lubricates both the gas and the steam turbine); c) new types of synthetic oils for aircr
18、aft turbines with land application; d) detailed classification for hydro-turbines, including environmentally acceptable products. This completes the classification described in ISO 6743-5:1988 and fits the industrial needs. BS ISO 6743-5:2006 Licensed Copy: London South Bank University, London South

20、 Part 5: Family T (Turbines) 1 Scope This part of ISO 6743 establishes the detailed classification of fluids of family T (Turbines) that belong to class L (Lubricants, industrials oils and related products). It is intended to be read in conjunction with ISO 6743-992. This classification excludes the
21、 products intended for aircraft turbines. However, some aircraft turbines can find land application for power generation. For the lubrication of such turbines, it is recommended that the manufacturers recommendation be followed. Depending on the service, either TGA, TGB, TGCH, TGCE or more specific
22、aircraft-turbine lubricants can be used. This classification also excludes the products intended for the lubrication of wind turbines. The gear lubricants used in wind turbines are described in ISO 6743-61 and specified in ISO 12925-13. 2 Explanation of symbols used 2.1 The detailed classification o
23、f family T has been established by defining the categories of products required for the various applications of this family. 2.2 Each category is designated by a symbol consisting of a group of letters, which together constitute a code. The first letter of the code (T) identifies the family of the p
24、roduct considered, but any following letters taken separately have no significance of their own. The designation of each category can be supplemented by a number denoting the viscosity grade of the lubricant in accordance with ISO 3448:19924. 2.3 In the present classification system, products are de
