TS 2822

TS 2822 is a standard covering the basic instruments used in technical drawing. By defining compasses, set squares, T squares, measure rules, drawing boards and related hand-drawing tools under a common framework, it helps clarify what these instruments are for and how they fit into drafting practice.

The shared role of drafting instruments

Technical drawing is the foundation of dimensional design and manufacturing documentation, so the tools used for it need to support accuracy, line control and repeatable results. Compasses are used for circles and arcs, set squares for right angles and fixed angular layouts, T squares for horizontal reference and parallel lines, and measure rules for reading and transferring lengths. Drawing boards provide a stable working surface for controlled drafting.

The instrument group covered by the standard

The scope brings together the instruments used in manual technical drafting. In practice, these tools form a coordinated set: some establish geometry, some support measuring and transfer, and others keep the drawing surface organised. Even where terminology varies in different drafting traditions, the central subject here is the classification and naming of technical drawing instruments rather than a single specialised tool.

• Core hand-drawing and guiding instruments used in drafting
• Tools that support line, angle and length transfer
• Equipment that helps maintain a stable drawing surface
• A complementary group of instruments used together in technical drawing

This record refers to a withdrawn standard, so it is best understood as a historical reference for the naming and grouping of technical drawing instruments. It remains useful for interpreting older drafting terminology and equipment classifications.
