ASME Y14.40.3:2002 pdf free download – GRAPHICAL SYMBOLS FOR DIAGRAMS, PART 3: CONNECTIONS AND RELATED DEVICES
1 SCOPE
This Standard specifies graphical symbols for func- tional connections, mechanical links, pipelines, 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 apply: NOTE: In those cases where the same term has substantially differ- ent meanings in ISO and IEC, this is indicatcd beside the term by [ISO1 or (IEC] and elsewhere in this Standard by a superscript, for example, “portS 0.”
3.1 connection: general term for functional connection, mechanical link, pipeline, electric conductor, etc.
3.2 functional cornection: connection between functions. NOTE: A functional connection is used to represent the interrela- tions between functions represented, for example, by symbols according to ASME Y1440.6.
3.3 electric connection: conductor or circuit for joining termi- nais or other conductors.
3.4 comnection [ISO]: threaded port, fange, or similar means for connecting a pipeline to a component, cf. port (3.13) and terntinal.
3.5 internal connection: connection in the formn of one or more pipelines or conductors that is an integral part of a com- ponent. NOTE: An internal connection need not be located inside a con- ponent.
