TS ISO 14617-2

TS ISO 14617-2 covers the general-purpose portion of graphical symbols used in diagrams; these symbols act as building blocks for constructing more complete symbols that represent specific products and functions. The focus of this part is not on detailed symbols for individual equipment items, but on a core set that can be reused across many kinds of technical diagrams.

The role of general-purpose symbols in diagrams

General application symbols help communicate function and structure in a compact, consistent way. In technical drawing and diagramming, that consistency supports a common visual language across disciplines, so a symbol family can be combined into larger representations of specific products. This is especially useful in design documentation, training, and technical communication, where readability and uniform interpretation matter.

How this part fits within the ISO 14617 family

The standard sits within the framework outlined in ISO 14617-1, which provides the overall introduction and the use of registration numbers, and it points to ISO 81714-1 for the fundamental rules for creating and applying graphical symbols. In other words, this part does not aim to describe the whole system by itself; it provides a defined source of general-character symbols that can be used consistently within the broader diagram symbol system. For users, that supports shared interpretation and a stable conceptual basis across different diagrams.
