This International Standard specifies the principle of the relationship between dimensional (linear and angular) tolerances and geometrical tolerances.

4 Principle of independency
Each specified dimensional or geometrical requirement on a drawing shall be met independently, unless a particular relationship is specified.
5 Tolerances
5.1 Dimensional tolerances
5.1.1 Linear tolerances
A linear tolerance controls only the actual local sizes (two-point measurements)of a feature, but not its form deviations (for example circularity and straightness deviations of a cylindrical feature or flatness deviations of two parallel plane surfaces (See ISO 286/1.)ISO 8015:1985 pdf download.
