TS ISO 128-1

TS ISO 128-1 sets out the general principles for presentation in technical drawings and introduces the structure of the ISO 128 series. It serves as the entry point to a common drawing language, helping different features, dimensions, notes, and graphical elements be read and interpreted consistently.

A common graphical language for engineering drawings

In general technical drafting practice, the aim is to communicate the shape of a product, its dimensional relationships, and the required technical information without ambiguity. The ISO 128 family brings together conventions such as line types, view arrangement, use of sections, and consistent presentation. TS ISO 128-1 acts as the gateway to that family: it outlines the subjects covered by the other parts and frames the overall approach to technical drawing presentation.

Where this part fits, and what it does not try to do

• Presents the structure of the other parts of the ISO 128 series and an index to them.
• Covers general rules for the execution of technical drawings.
• Functions as an introductory guide rather than a complete stand-alone catalogue of detailed drawing rules.

In broader engineering use, standards of this kind help ensure that graphical symbols and presentation methods carry the same meaning across design, manufacturing, inspection, and documentation. This standard is therefore useful as a framework for understanding technical drawing practice and for navigating to the relevant parts of the ISO 128 series.
