ISO 128

ISO 128 is an international standard (ISO), about the general principles of presentation in technical drawings, specifically the graphical representation of objects on technical drawings.

[1] Since 2003 the ISO 128 standard contains fifteen parts, which were initiated between 1996 and 2003.

It starts with a summary of the general rules for the execution and structure of technical drawings.

[1] The ISO 128 replaced the previous DIN 6 standard for drawings, projections and views, which was first published in 1922 and updated in 1950 and 1968.

ISO 128 itself was first published in 1982, contained 15 pages and "specified the general principles of presentation to be applied to technical drawings following the orthographic projection methods".
