In preparing the list of pipe fittings, valves, and piping symbols for use on drawings, over one hundied companies and their representatives were consulted. Great care was exercised to avoid conflicts with the symbols being assembled by committees in allied fields. T h e 73 s y m b l s s h o w n are a minimum requirement. Many other piping symbols exist; for instance, such as those used in petroleum piping. Following apprpval of the sectional committee and the sponsor organizations, thisproposalwasapprovedbytheAmericanStandardsAssociationon,April 1949, and designated a s 232.2.3-1949.

GRAPHICAL SYMBOLS FOR PIPE FITTINGS, VALVES, AND PIPING scope

This standard has been developed for use on drawings. Architects, engineers, and confractors, by the use of t h e s t s y m b o l s on their plans, will have a standard method of indication for pipe fittings, valves, piping m.d allied itcms. Confusion in the interpretations of r e q u i r e m e n t s c a n t h u s be avoided.

B a s i c Priaciples Clarity and simplicity were, considered paramount in the assembling of these symbols.Wheneverpossible,simplification in thedraftingwasprimarily considered and identification letters were used only when there was a question of a n error because of similarity of form. Only those symbols, about which there was nationwide consensus, were included. There are still maay symbols t h a t are used in a particular section but are not nationally recognized.
