Example of tolerancing for cones as specified in ISO 3040 standards.
Rate of Taper Explained:

The Rate of Taper (C) is the ratio of the difference in the diameters of two sections of a cone to the distance between them. It is expressed by the formula C = (D-d)/L, as illustrated in the technical drawings.
