This document specifies the recommended proportions for the symbols used on technical product documentation. It gives recommended dimensions based on the grid related to the line width to be used.

This standard does not apply to symbols used in process plant documentation which is covered in ISO 81714-1.

The proportions of the symbols are based on the standard heights of lettering given in IS0 3098-l.

This document gives the rules for geometrical dimensioning and tolerancing of final moulded parts andparts machined out of moulded parts. It also gives rules and conventions for the indications of theserequirements in technical product documentation and specifies the proportions and dimensions of thegraphical symbols to be used.

This document provides symbols which may be used to identify the relative completeness of the moulded features and parts. These graphical symbols should not be confused with the graphical symbols for surface texture according to ISO 1302, which are notably larger.

This document specifies general geometrical tolerances using surface profile tolerances related to a general datum system that remains on the final part. It specifies also machining allowances and draft angles (tapers) for castings in all cast metals and their alloys produced by various casting manufacturing processes.

This document establishes the general principles for presentation of general geometrical tolerances that apply to 2D technical drawings in all disciplines and trades but which can also be applied to 3D applications.

NOTE All figures are shown in 2D views only.

When cast datum surfaces are machined, this part of ISO 8062 is not applicable
