20、dization) 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 committee has been established has the right to

21、 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 electrotechnical standardization.The procedures used

22、 to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of

23、 the ISO/IEC Directives, Part 2 (see www.iso.org/directives).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 identifying any or all such patent rights. Details of any patent rights identified

24、during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the

27、O 14084-2:2015(E)IntroductionGeneralThis part of ISO 14084 deals with preparation of process diagrams for power plants.ISO/TC 10/SC 10 prepares standards for diagrams including graphical symbols which together with standards prepared by other ISO committees and IEC constitute the basis for preparati

28、on of diagrams for process industry.The interrelations between these standards are illustrated in Figure 1.

29、ollective application standardISO/TC 10/SC 10 standards: ISO 15519-series: Specifications for diagrams for process industry; ISO 14617-series: Graphical symbols for diagrams;are basic standards, which are general and apply to all fields of applications. Technical committees working in a specific app

30、lication field are allowed to make extracts and publish them as collective application standards of ISO 15519-series, ISO 14617-series or both.Application fieldsThis International Standard applies to the power plant field, which include conventional fossil and biomass fired power plants, hydro power

31、 plants, sea wave power plants, wind power plants, nuclear power plants, geothermal power plants, solar power plants, osmosis power plants, incineration plants, and industrial power plants.

38、ols for diagrams for power plants. In case a needed symbol cannot be found in this International Standard or in ISO 14617-series then, the needed graphical symbol example should be created on basis of basic and supplementary graphical symbols in ISO 14617 as illustrated in Annex A.In case the needed

39、 graphical symbol neither exists in ISO 14617 nor can be created on basis of basic and supplementary symbols in ISO 14617 then, a new graphical symbol shall be requested according to ISO/IEC Directives, Part 1, Consolidated ISO Supplement, 2014, Annex SH.4.4 Symbols for large/complex objectsGraphica

40、l symbols for large and complex objects like boilers, turbines, flue gas treatment plants, boiler feed pumps, etc. are not standardized in this International Standard.In diagrams, large and complex objects should be represented with a silhouette which allow for correct placement of graphical symbols
