This International Standard specifies the general principles of presentation to be applied to technical drawings following the orthographic projection methods.

Additional International Standards are under preparation for other methods of representation.

This International Standard is intended for all kinds of technical drawings (mechanical, electrical, architectural, civil engineering, etc.). However, it is recognized that in some specific technical areas the general rules and conventions cannot adequately cover all the needs of specialized practices, and that additional rules are required which may be specified in separate standards. For these areas the general principles should however, be respected in order to facilitate international exchange of drawings and to ensure the coherence of drawings in a comprehensive system relating to several technical functions.

Attention has been given in this International Standard to the requirements of reproduction, including microcopying.
