Foreword
T HE development of these symbols under the American Standards Association procedure h a s been sponsored by The American Society of Mechanical Engineers and the American :Institute
of Electricd Engineers. The cooperation of the American Petroleum .Institute, American Institute of Chemical Engineers,
Instrument Society of America, and the National Electrical Manufacturers Association is hereby acknowledged together with the response received from over GO individual companies who sub- mitted their drawing symbols for review and consideration by the Task Grnup.
Following appro.va1 by the Sectional Committee and the sponsors, this Standard was approved by the American Standards Association and received i ts designation on September 11, 1961.

O AMERICAN STANDARD
Graphical Symbols for
Process Flow Diagrams
1. SCOPE
This preliminary s e t of standard symbols has been developed for use on the basic process flow diagrams in order to represent the major items of equipment used by the petroleum and chemical industries.
A process flow diagram is the first drawing made to show the basic items of major equipment and their relation to one another in the process scheme, The more important flow lines are indi- cated as connecting these pieces of equipment and help to describe how the process operates.
2. BASIC PRINCIPLES
Simplicity of outline form were considered as paramount in the development of these symbols. The main idea i s to preserve the general physical appearance of the equipment, with the minimum strokes to a draftsman.
So scale is applied to a process flow diagram, but the relative size of the symbols should be selected in keeping with the overall size of the
5
completed drawing, The symbols should be ar- ranged on the drawing in logical sequence of flow, from the charge material to the main product, with a minimum of cross-over lines.
It is suggested that the equipment outlines be drawn by heavy lines, and that the connecting piping be shown a s lighter lines. For the putpose o f most process flow diagrams it is not considered necessary to indicate any insttumentation o r electrical symbols.
3. GENERAL
The following 79 symbols are by no means all that were suggested or that may be required; however, by adopting these as a standard the majority of present processes may be adequately represented.
In the preparation of final drawings for the de- tailed design, erection or operation of a unit, the process flow diagram m u s t be supplemented by the more detailed engineering flow sheets and the final piping layout drawings.
