This International Standard specifies the recommended propor-tions and lays down the dimensions for the symbols used to in-dicate geometrical tolerancing on technical drawings.
The symbols and their lettering may be hand-written (using a rule for drawing the frames) or executed by means of other ap-propriate methods (for example, stencils, transfers, mechanical drawing, etc.).
The dimensions of the symbols are based on the standard heights of lettering given in ISO 3098/1.
