It should be noted, however, that the ISO standards do not always keep abreast of developments in pneumatics technology, so that new products often fail to be clearly defined until some time after their introduction. ![]() Standard ISO symbol conventions are therefore intended to represent graphically the function, not the construction or appearance, of each device. ![]() With certain obvious exceptions symbols may be reversed and/or rotated without altering their meaning’. The symbols do not indicate the physical location of ports or the position of control elements on actual components. ![]() The symbols show connections, flowpaths and the functions of the components represented. This states that: ‘A symbol consists of the lines, letters and abbreviations which identify the purpose and method of operation of the component represented. The symbols used for constructing fluid power systems and for defining individual components are detailed in the standard ISO 1219, which covers both pneumatic and hydraulic devices. By following these guidelines engineers can quickly and simply construct circuits that can be easily and safely interpreted by all those involved in system design, specification, manufacturing and maintenance. ![]() Pneumatic circuits are represented by common symbols and should be drawn following several basic guidelines.
