1 ScOPE
This Standard specifies graphical symbols for func-tionai connections, mechanicai links, pipeiines, andrelated devices such as connection joints, ISO ports, ter-minals,quick-release couplings, and connectors, in dia-grams.
For the fundamental rules of creation and applicationof 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 foridentifying graphical symbols used in diagrams, rulesfor the presentation and application of these symbols,and examples of their use and application,see ASMEY14.40.1.
