TS EN ISO 6412-2

TS EN ISO 6412-2 is the standard for simplified representation of pipelines in technical drawing, focusing on the use of isometric projection. It defines the drawing rules used to present a three-dimensional piping arrangement in a readable single-view form and complements the general rules of the same family of standards.

What isometrict representation is for

In technical drawing, isometric projection is a way of showing depth and spatial direction with a fixed relationship between the three axes. For pipeline drawings, this makes the route, direction changes, junctions and connections easier to understand. In general technical practice, a simplified representation does not aim to show every exact geometric detail; instead, it communicates the arrangement and connection logic of the system clearly and consistently.

What this standard covers

According to the supplied scope, this part specifies supplementary rules for applying isometric representation. In other words, it addresses how isometric projection is used together with the general rules of technical drawing for pipeline layouts. Standards of this kind typically support consistent conventions for linework, direction changes, dimensioning approach, component placement and overall legibility.

• Simplified technical representation of pipelines
• Drawing practice based on isometric projection
• Supplementary provisions used together with general technical drawing rules
• Representation principles that help make routes, connections and layout readable at a glance

The standard provides a common visual language for technical drawing, mechanical installation and piping systems. In complex layouts, it helps different disciplines work from the same drawing with consistent interpretation, supporting clearer design communication, fabrication preparation and documentation.
