The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3040 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product specifications and verification. This third edition cancels and replaces the second edition (ISO 3040:1990), which has been technically revised.

It influences chain links 1 and 2 of the chain of standards on angles. For more detailed information on the relation of this International Standard to other standards and to the GPS matrix model, see Annex B. In this International Standard, the figures illustrate the text only and should not be considered as design examples. For this reason, the figures are simplified and are not to scale.

For the purposes of this International Standard, the term “cone” relates to right-angle circular cones only. 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. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 1119:1998, Geometrical Product Specifications (GPS) — Series of conical tapers and taper angles ISO 81714-1, Design of graphical symbols for use in the technical documentation of products — Part 1: Basic rules 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 rate of taper C ratio of the difference in the diameters of two sections of a cone to the distance between them NOTE lt is expressed by the following formula (see also Figure 1): 2tan2DdCLα− ⎛⎞==⎜⎟⎝⎠Copyright International Organization for Standardization Provided by IHS under license with ISO Not for ResaleNo reproduction or networking permitted without license from IHS--`,,```,,,,````-`-`,,`,,`,`,,`---ISO 3040:2009(E) 2 © ISO 2009 – All rights reservedFigure 1 4 Graphical symbol for a cone A cone shall be indicated using the graphical symbol illustrated in Figure 2 positioned on a reference line (see Figure 7). The orientation of the graphical symbol shall coincide with that of the cone (see Figure 7 and Figure 8). For the size and line thickness of the graphical symbol, see ISO 81714-1. Figure 2 5 Dimensioning of cones 5.1 Characteristics of cones In order to define a cone, the characteristics and dimensions shown in Table 1 may be used in those combinations most appropriate for the function of the cone.

However, additional dimensions (for example, half the included angle) may be given as “auxiliary” or “reference” dimensions in brackets for information. Typical combinations of cone characteristics and dimensions are shown in Figure 3, Figure 4, Figure 5 and Figure 6.

The reference line shall be drawn parallel to the centreline of the cone, and the orientation of the graphical symbol shall coincide with that of the cone. Key 1 leader line 2 graphical symbol 3 reference line Figure 7 5.3 Standardized series of cones When the taper to be indicated is one of a standardized series of conical taper (in particular Morse or metric taper), the tapered feature may be designated by specifying the standard series (see ISO 1119) and appropriate number (see Figure 8).
