Overview
ISO 3098-6:2000 is the International Standard that defines the Cyrillic (Russian) alphabet for technical product documentation and lettering. As part of the ISO 3098 series on lettering, this part specifies how Cyrillic characters should be formed for use in technical drawings, associated documents, labels and symbols. The standard was published in 2000 and primarily addresses stencil lettering but is also applicable to freehand and other lettering methods.
Key topics and requirements
- Character set: Specifies the Cyrillic Russian alphabet characters used as text and symbols in technical drawings. (Other Cyrillic alphabets with additional characters should follow the same formation principles.)
- Letter formation: Characters are formed so that lines cross or meet at approximately right angles to ensure consistent line density and to avoid blotting at intersections.
- Orientation styles: Includes recommended samples for both vertical and sloping lettering styles, illustrating practical application of the general requirements.
- Method applicability: Primarily intended for stencil-produced lettering but explicitly applicable to freehand or other appropriate lettering methods.
- Dimensional and general requirements: Refers to ISO 3098-0 for general requirements, character dimensions, numerals and marks. Users must consult ISO 3098-0 for precise sizing, line thickness and spacing rules.
Practical applications
- Engineering and mechanical drawings where Cyrillic text or labels are required
- Architectural plans, schematics and electrical diagrams used in Cyrillic-language regions
- Product documentation: parts lists, assembly instructions, technical manuals, and nameplates
- Manufacturing and quality control where standardized stencil lettering improves legibility and interchangeability
- CAD drafting where Cyrillic lettering must conform to international documentation conventions
Who uses this standard
- CAD technicians and draughtsmen working on drawings in Cyrillic languages
- Mechanical, electrical and architectural engineers producing technical documentation
- Technical writers and document controllers preparing manuals and specification sheets
- Manufacturers applying labels, nameplates or stencil marks on parts and assemblies
- Standards bodies and compliance officers ensuring documentation meets ISO conventions
