TS 5793

TS 5793 is the Turkish edition of the standard dealing with plastic triangles used in school and office technical drawing and project work. Triangles are basic drawing tools used to construct specific angles, guide parallel and perpendicular lines, and support accurate layout in manual drafting. As indicated by the title, the standard concerns triangles made of plastic rather than metal or other materials.

Where triangles fit in drafting equipment

In general technical use, a triangle works alongside tools such as rulers, compasses and protractors. Plastic triangles are common in educational and office settings because they are light, often transparent, and do not block the drawing surface as much as opaque tools. In technical drawing, reliable angle formation and edge alignment matter for legibility and orderly geometry, so triangles remain useful in foundational drafting training, plan preparation and sketch development.

What the standard covers in practical terms

The scope of this standard is limited to plastic triangles used for technical drawings and project work in schools and offices. In other words, it defines a specific product category rather than all drafting instruments. The cited references show that it was aligned with contemporary national and international practice of its time, but this listing alone does not establish the exact dimensions, tolerances, markings or material details contained in the standard. TS 5793 should therefore be understood as a framework document for identifying and classifying plastic triangles in technical drawing contexts.
