Provides guidance on a system of cone fits and tolerances for cones from C = 1:3 to 1:500 and lengths from 6 mm to 630 mm.

This British Standard gives guidance on a system of cone fits and tolerances for cones from C =1:3 to 1:500 and lengths from 6mm to 630mm.

The appropriate tolerances of this British Standard can also be used for prismatic workpieces, for example wedges.

This British Standard applies to cones which are dimensioned and toleranced according to BSISO3040, Method 1, Basic Taper method. This means that the tolerances limit the variation of penetration of mating surfaces, each surface being within two limiting profiles of the same taper corresponding to the maximum material condition (MMC) and the least material condition (LMC).

This British Standard is derived from BSEN20286, and is a complement to BSENISO1119.

NOTE For dimensioning and tolerancing cones on drawings, see BSISO3040.
