TS EN 81714-3

TS EN 81714-3 addresses the classification of connect nodes, networks and their encoding in the design of graphical symbols used in the technical documentation of products. It focuses on the way functional concepts are represented consistently in drawings and computer-based technical information systems.

A common classification basis for nodes and networks

According to the scope of this part of 81714, the same classification principles are applied both to connect nodes associated with products and to networks and their graphical representation. This is important where the product and its graphical expression are closely interrelated, because the classification must remain consistent across the physical item, its functional meaning and its symbol-based representation.

In general technical terms, a connect node is a point where elements are linked, while a network describes the relationship structure created by those links. In technical documentation, a clear and stable encoding of these elements supports readable diagrams, data exchange and automated symbol handling in computer-aided systems.

Why encoding matters in technical documentation

• The standard deals with the classification of connect nodes used in graphical symbols.
• It links product concepts and functional concepts through a shared documentation logic.
• It extends the same classification principles to networks and their representation.
• It supports consistency in computer-aided technical documentation environments.
