TS EN ISO 6412-1

TS EN ISO 6412-1 is a technical drawing standard for the simplified representation of pipes and pipelines using an orthogonal drawing approach. It defines general rules for showing piping systems in a clearer, more compact way, regardless of the material used. The standard is aimed at making complex pipeline layouts easier to read in engineering documents.

Why simplified pipeline representation matters

In technical drafting, piping is often represented without reproducing every geometric detail of the actual installation. This is a practical drawing method used to communicate route direction, branching, connections, and overall arrangement efficiently. Orthogonal representation supports that goal by expressing the layout through straight, right-angled views, which helps keep plans, elevations, and related views consistent and readable.

According to the scope of this standard, the rules apply to all kinds of pipes and pipelines, independent of material. In general engineering practice, that means piping made from steel, plastics, copper, or other materials can be shown within the same simplified graphical logic. The benefit is a more uniform visual language for fabrication drawings, installation documents, maintenance records, and project coordination.

This document is Part 1 of the TS EN ISO 6412 series and focuses on general rules and orthogonal representation. Used together with core technical drawing standards such as ISO 128, ISO 129, and ISO 3098-1, it supports consistent linework, dimensioning, lettering, and overall drafting practice.

• Scope: simplified representation of all kinds of pipes and pipelines
• Core idea: communicate layout clearly rather than reproduce full geometry
• Representation type: orthogonal, right-angled views
• Material-independent rules: applicable across piping materials
