14、1:2015ISO 14084-1:2015(E)ForewordISO (the International Organization for Standardization) 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
15、 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 International Electrotechnical Commiss
16、ion (IEC) on all matters of electrotechnical standardization.The procedures used 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 shou
17、ld be noted. This document was drafted in accordance with the editorial rules of 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 ide
18、ntifying any or all such patent rights. Details of any patent rights identified 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 conven
19、ience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WTO principles in the Technical Barriers to Trade (TBT), see the following URL: Foreword

22、ed by other ISO committees and IEC constitute the basis for preparation of diagrams for process industry.The interrelations between these standards are illustrated in Figure 1.

Technical committees working in a specific application field are allowed to make extracts and publish them as collective application standards of ISO 15519 series, ISO 14617 series, or both.0.3 Application fiel
26、dsThis part of ISO 14084 applies to the power plant field, which includes conventional fossil and biomass-fired power plants, hydropower plants, sea wave power plants, wind power plants, nuclear power plants, geothermal power plants, solar power plants, osmosis power plants, incineration plants, and
27、 industrial power plants.0.4 FiguresFigures in this part of ISO 14084 are only examples for illustration of a given rule.vi ISO 2015 All rights reservedBS ISO 14084-1:2015ISO 14084-1:2015(E)0.5 Reference designationIn this part of ISO 14084, ISO/TS 16952-10 is used for illustration of rules and guid
28、elines for the use of reference designation in process diagrams for power plants.A summary of ISO/TS 16952-10 is given in Annex C.NOTE In case of application of another reference designation system, its application in diagrams has to be interpreted analogously.

35、low path and process measurement, and control functionsNote 1 to entry: The diagram type process and instrumentation diagram, used in this part of ISO 14084, is technically identical with the piping and instrumentation diagram. The argument for change of the designation in this part of ISO 14084 is
36、that the power plant field uses this document type for both fluid and solid material processes. The abbreviation used in this part of ISO 14084 for the process and instrumentation diagram is PID which deviates from the traditional used abbreviation P the technology used for development of diagrams t
