Annex
A. Effect on the cone fit of departures of the
internal and external cones from the basic cone
Tables
1. Axial displacement ENT of the internal cone and
the external cone respectively, with regard to the
basic cone resulting from the standard tolerances
IT 01 to IT 16 according to ISO 286 for the basic
cone diameter - For rate of taper C = 1:10
2. Axial displacement ENemin of the external cone
with regard to the basic cone resulting from the
fundamental deviations a to zc according to ISO 286
for the basic cone diameter of the external cone
for rate of taper C = 1:10
3. Conversion factors to be applied to the values
given in tables 1 and 2 for the axial displacement
of all rates of taper other than C = 1:10

displacement of the cones with respect to each
other from the actual starting position Pa

assembly from the actual starting position Pa

workpiece with regard to the basic cone
6. Maximum and minimum interference of a cone
interference fit made by a defined axial displace-
ment of the cones with respect to each other from
the actual starting position Pa

8. Contact lengths Lt of the fit surfaces
9. Position of the cone angle tolerance AT on both
sides with regard to the basic cone angle alpha
10. Position of the cone angle tolerance AT on one
side with regrad to basic cone angle alpha with the
same sign for ATe and ATi
11. Position of the cone angle tolerance AT on one side
with regard to the basic cone angle alpha with
opposite sign for ATe and ATi
