TS ISO 14617-15

TS ISO 14617-15 is the part of ISO 14617 that addresses graphical symbols used on installation diagrams and network maps. Its focus is practical and visual: the symbols help identify the location and type of a component or device, especially in building-related installation drawings and in diagrams that represent networked arrangements.

In the ISO 14617 system, this part supplements the symbols defined in ISO 14617-2 through ISO 14617-12. From a general technical perspective, that means it extends a broader symbol vocabulary so designers can present layout, connectivity, and equipment identity in a concise and consistent way. This improves readability in technical documentation, where diagrams often need to communicate structure faster than text alone.

How the symbol system is organised in technical drawings

Installation diagrams usually show how equipment is arranged in a physical setting, such as a building, while network maps emphasise links between nodes and devices. In both cases, the value of standardised graphical symbols lies in reducing ambiguity: a reader can understand what is installed, where it is placed, and how it relates to other elements without relying on long descriptions. The standard also points users to ISO 81714-1 for the fundamental rules for creating and applying graphical symbols, and to ISO 14617-1 for the overall framework of ISO 14617 and the use of registration numbers.
