1 SCOPE
This Standard specifies graphical symbols for func- tionai connections, mechanicai links, pipeines, and related devices such as connection joints, ISO ports, ter- minals, quick release couplings, and connectors, in dia- grams. . For the fundamental rules of creation and application of graphical symbols in diagrams, see ASME Y14.40.0. For an overview of the ASME Y14.40 series, informa- tion on the creation and use of registration numbers for identifying graphical symbols used in diagrams, rules for the presentation and application of these symbols, and examples of their use and application, see ASME Y14.40.1.

3 TERMS AND DEFINITIONS
For the purposes of this Standard, the following terms and definitions appiy: NOTE: In those cases where the same term has substantially differ- ent meanings in ISO and IEC, this is indicated beside the term by [ISO] or [EC] and eisewhere in this Standard by a superscript, for example, “portSO.” 3.1 connection: general term for functional connection, mechanicai link, pipeiine, eiectric conductor, etc. 3.2 furctiorul cornecion: cornection between functions. NOTE: A functional connection is used to represent the interrela- tions between functions represented, for example. by symbols according to ASME Y14.40.6. 3.3 electric connection: conductor or circuit for joining termi- nals or other conductors. 3.4 connection [iSO]: threaded port, fiange, or similar means for connecting a pipeline io a cormponent, cf. purt (3.13) and terminal. 3.5 interna! connection: connection in the form of one or more pipelines or conductors that is an integral part of a com- ponent. NOTE: An intemal connection need not be located inside a cum- ponent. 3.6 line [ISO]: abbreviation of the term“pipeline.” 3.7 line [IEC]: multi-pole or multi-phase electric connection. EXAMPLE: Power line, telecommunication line, transmission line. 3.8 cable: insulated conductor or several insulated conduc- tors with a common covering. 3.9 pipe unit: pipeline or, more often, several pipelines in a common covering pipe with insulation. 3.10 informnation bus: bus with conductors cunveying infur- mation. 3.11 unidirectional: having the property to move, transmit, etc. in one direction only. 3.12 bidirectionai: having the property to move, transmit, etc. in iwo alternative, opposite directions. 3.13 port ISO]: terminus of a fluid passage in a component to which can be cornnected pipelines for the bransmission of fluid to or from the component, cf. connection (3.4) and terminal. 3.14 connector: component which terminates conductors, flex- ible pipes, or hoses in order te provide connection and disconnection to a mating component, cf. connector pair (3.16). 3.15 gquick- release coupling: connection (3.4) which may be joined or separated without the use of tools. . 3.16 connector puir: combination of mating corunectors. 3.17 bundle: group of conductors or pipelines that mainly follow the same path. NOTE: The bundle may be a real (product) bundle or a line on a diagram representing a ruber uf cunduciurs or pipelines (singie- line representation) even if these do not form a real bundle. 3.18 single-line represenlation: representation where two or more connections or components are represented by a singlc symbol.
