TS 12693

TS 12693 is a professional standard for the machine technical draughtsman, defining the occupation, describing how the practitioner is classified, and addressing the minimum tools and equipment used in the trade. It also provides a framework for measuring and evaluating the characteristics expected from a person who holds the technical draughtsman title. In general technical terms, drafting in machinery is the discipline that translates engineering information into drawings using dimensions, views, sections, tolerances, and standard symbols.

What makes machine drafting a distinct field

The standard focuses on mechanical drafting, where drawings communicate the geometry, assembly, and manufacturing intent of machine parts and systems. This is distinct from construction, electrical, electronic, and map drafting, because the central concern here is the representation of mechanical components and their production requirements. That distinction matters in practice: the notation, drawing conventions, and workplace skills differ across these drafting domains.

Tools, competence, and assessment

The standard takes into account the minimum tools and equipment used in the profession; in the wider drafting context these typically include drawing surfaces, measuring tools, straightedges, set squares, compasses, and related drafting aids. Its assessment-oriented aspect is equally important: beyond drawing technique, the occupation relies on accuracy, technical communication, reading dimensions correctly, and using drafting standards and symbols consistently.

• The subject is machine technical drafting; construction, electrical, electronic, and map drafting are excluded.
• Definition and classification of the occupation are core elements of the standard.
• Minimum tools and equipment are treated as part of the professional setup.
• The standard includes a framework for measuring and evaluating professional characteristics.
• In general technical context, the field sits at the intersection of manufacturing drawings and technical communication.
