TS ISO 14617-12

TS ISO 14617-12 covers graphical symbols used to represent separating, purification and mixing devices in diagrams. It is aimed at the symbolic language used in process schematics, plant diagrams and similar technical drawings, where equipment function needs to be conveyed quickly and consistently.

The standard addresses the representation of the devices in diagrams, not the physical design of the equipment itself. In general technical practice, these symbols help engineers and draughting teams show functions such as phase separation, purification steps or blending operations without lengthy text labels. That makes it easier to read process flow diagrams, understand equipment relationships and follow the material path through a system.

How these device categories differ in diagrams

Separation, purification and mixing are related but distinct operations. Separation devices split a mixture into components or streams, purification devices reduce or remove unwanted constituents, and mixing devices combine materials to achieve a more uniform product or stream. In a process train, these functions may appear in sequence, so precise symbol choice matters for correct interpretation of the diagram.

This part is linked to the general symbol-creation and application principles in ISO 81714-1, and to the broader ISO 14617 framework described in ISO 14617-1. In that context, registration numbers and presentation rules support consistent identification and use of graphical symbols across technical documentation.
