TS EN ISO 6412-3

TS EN ISO 6412-3 is Part 3 of the technical-drawing series for simplified representation of pipelines, focused on terminal features for drainage systems and ventilation systems. In practice, standards of this kind help turn dense piping information into a clearer drawing language, where the emphasis is not on reproducing every geometric detail but on showing, consistently and unambiguously, what kind of end feature appears at the line termination.

Why terminal features matter in piping drawings

In general technical practice, drainage and ventilation systems are both common in building services and plant documentation. Drainage concerns the removal of liquids, while ventilation supports air movement and pressure equalisation. Simplified representation is valuable because it reduces drawing clutter while preserving design intent. Terminal features are the cues that identify open ends, outlets, or the final connecting element of a pipeline, which helps distinguish lines that may otherwise look similar on a plan or schematic.

Where this part fits in the document family

• This standard belongs to the TS EN ISO 6412 family for simplified pipeline representation in technical drawings.
• Its title shows a specific focus on terminal features for drainage and ventilation systems.
• Such representation is commonly useful in layout drawings, coordination drawings and general arrangement documentation.
• This record is withdrawn, but it can still be relevant for legacy drawings and technical terminology reference.
