TS ISO 14617-5

TS ISO 14617-5 addresses graphical symbols used to represent components and devices in measurement and control systems on diagrams. It provides a standardized visual language for technical documentation, helping engineers and technicians describe the functional structure of plants, machines, and processes in a clear and consistent way.

In general technical practice, measurement and control diagrams show how sensors, indicators, transducers, controllers, and related elements interact. Graphical symbols replace lengthy textual descriptions and make engineering drawings faster to read, easier to compare, and more widely understandable across disciplines and organizations. The focus of this part is the symbol set for those devices as used in diagrams; for the fundamental rules of symbol creation and application, the standard points to ISO 81714-1, and for the overall structure of the ISO 14617 series and the use of registration numbers, it refers to ISO 14617-1.

Why symbol distinction matters in measurement and control

In measurement and control work, the same physical item may need to be shown differently depending on its function in the system. Standardized symbols therefore support not only neat drafting but also correct technical interpretation. Distinguishing a measuring element from a control element, or a signal converter from an indicator, helps reduce ambiguity in operations, maintenance, training, and documentation. TS ISO 14617-5 serves this need by defining a common graphical language for this technical field.
