26、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 committee has been established has the right to be represented on that committee. Inte
27、rnational 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. International Standards are drafted in accordance with th
28、e 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 member bodies for voting. Publication as an International Standard requires approval b

38、 transmitted and controlled through a fluid (liquid or gas) under pressure within a circuit. Circuit diagrams are an aid to facilitate the understanding of the design and description of installations so that, by having unified representations, confusion and error can be avoided during planning, manu
39、facturing, installation and maintenance. For a clear identification of the components shown on the circuit diagram, a component identification code is used. The structure provided with the first edition of ISO 1219-2 consisted of the following levels: installation, circuit and component. In addition
40、, for components, a letter for the identification of groups of components, for example P for pumps, and V for valves, was used. With the publication of IEC 1346-1:1995, the principle of structuring of installations in accordance with ISO 1219-2 was accepted, but in IEC 61346-2:2000 different letter
41、symbols for the classification of objects were provided. To avoid any potential misunderstanding caused by the use of letter symbols for groups of components, no letter symbols are used for the identification code of components in this edition of ISO 1219-2.
