TS 10841 EN ISO 3098-2

TS 10841 EN ISO 3098-2 is the Turkish adoption of the standard covering Latin alphabet letters, numerals and marks used in technical product documentation and related technical drawings. In this field, lettering is not only a matter of appearance; it also affects how dimensions, notes and identification data are read and interpreted consistently across documents.

The role of lettering in technical drawings

The standard primarily concerns characters written with the aid of stencils, but it can also be applied to freehand lettering or other suitable methods. In general technical practice, consistent letterforms, clear numerals and well-defined marks help drawings remain legible and reduce the risk of confusion in dimensioning, part identification, annotation and revision information. This makes lettering standards an important part of document clarity in engineering communication.

What this subject covers in practice

• Basic Latin-character forms used in technical written information.
• Numerals and marks intended for consistent appearance on technical drawings.
• Stencil-based lettering as the primary reference, with other suitable methods also allowed.
• Use in technical drawings and associated engineering documents.

This part belongs to the lettering series within technical product documentation. In practical use, attention to legibility, character distinction and layout helps reduce misreading during design review, production, inspection and communication between teams.

The standard focuses on how Latin-script lettering should be represented in technical documentation; it does not by itself define the drawing content, product design decisions or performance requirements. Its value lies in providing a controlled writing framework for clear and consistent technical communication.
