7.4 Scale of drawings

If the scale of the figure is such that all the essential details would not be clearly distinguished if the figure is reproduced, electronically or photographically, with a linear reduction in size to two-thirds, then the figure must be redrawn to a larger scale, and if necessary the figure should be split up into partial figures so that a linear reduction in size to two-thirds is still intelligible.

The graphic representation of the scale of drawings in cases where its inclusion is considered useful must be such that it is still usable when the drawing is reproduced in reduced format. This excludes indications of size such as "actual size" or "scale ½", both on the drawings and in the description, in favour of graphic representations of the scale.
