ISO 3040:2016 pdf free download.Geometrical product specifications (GPS) Dimensioning and tolerancing Cones Spécifi cation géométrique des produ its (GPS) — Cotation et tolérancement — Cones.
This ISO 3040 specifies graphical indication applicable to a cone (right-angle circular cones) to define its dimensioning or to specify its tolerancing.
For the purposes of this International Standard, the term “cone” relates to right-angle circular cones only (any intersection by a plane perpendicular to the axis of the nominal cone is a circle).
NOTE 1 For simplicity, only truncated cones have been represented in this International Standard. However, this International Standard can be applied to any type of cone within its scope.
NOTE 2 This International Standard is not intended to prevent the use of other methods of dimensioning and tolerancing.

Basic rules
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
5.2 Indication of rate of taper value on drawings
The graphical symbol with the rate of taper value of a cone shall be indicated near the feature according to the rules presented in Clause 4.
As shown in Figure 7, the reference line attached to the graphical symbol shall be:
— drawn parallel to the cone axis, and
— connected by a leader line to the outline of the cone.
When the taper belongs to a standardized series of conical taper (in particular Morse or metric taperJ, the rate of taper value of the cone may be replaced by the codification given by standard series according to Iso 1119 and appropriate number (see Figure 8). For example, the rate of taper value “1:20,047” may be replaced by the codification “Morse No. 1”.ISO 3040:2016 pdf free download.
