1. Scope and field of application
2. References
3. Formation of cone fits
4. Definitions
5. Calculation of axial displacements for the hole
    basis system of cone fits
6. System of cone fits
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
Figures
1. Cone clearance fit made by constructional formation
2. Cone interference fit made by pressing in to a
    defined dimension
3. Cone interference fit made by a defined axial
    displacement of the cones with respect to each
    other from the actual starting position Pa
4. Cone interference fit made by a defined force of
    assembly from the actual starting position Pa
5. Axial displacements EN of the single conical
    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
7. Limit starting positions
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

Applies to cones which are dimensioned and toleranced according to method 1 (basic taper method) of ISO 3040. Specifies a hole basis system of fits.
