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. Internationa organizations, governmental and non-governmental, in liaison with Iso, also take part in the work. ISo collaborates closely with the International Electrotechnical Commission (EC on all matters of electrotechnical standardization The procedures used to develop this document and those intended for its further maintenance are described in the ISo/EC Directives, Part 1. In particular the different approval criteria needed for the different ty pes of Iso documents should be noted. This document was drafted in accordance with the editorialrulesoftheIsO/iecDirectivesPart2(seewww.iso.org/directives) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

Nevertheless, for many purposes (the functioning of a part or out of safety considerations, for example) particular conditions of edges need to be indicated Such conditions include those of external edges free from burr or those with a burr of limited size, and internal edges with a passing. This document provides a symbology for the indication of the desired edge ISo 2017-All rights reserved BS|So13715:2017 BS|So13715:2017 INTERNATIONAL STANDARD Is013715:2017(E Technical product documentation- Edges of undefined shape - Indication and dimensioning 1 Scope This document specifies rules for the indication and dimensioning of undefined edges in technical product and dimensions. The proportions and dimensions of the graphical symbols to be used are also specifie In cases where the geometrically defined shape of an edge (for example, 1 x 45)is required, the general dimensioning principles given in ISo 129-1 apply 2 Normative references There are no normative references cited in this document 3 Terms and definitions For the purposes of this document, the following terms and definitions apply ISO and IEC maintain terminological databases for use in standardization at the following addresses IeceLEctropedia:availableathttp://www.electropedia.org IsoOnlinebrowsingplatformavailableathttp://www.iso.orglobp 3.1 edge of undefined shape transition line, included in an intersection plane, which is not defined on the nominal model and which exists between two adjacent integral surfaces 3.2 undercut deviation inside the ideal geometrical shape of an edge defined by two tangent outside straight lines to the adjacent feature of the zone of the undefined edge only the undercut and the two tangents outside straight lines are represented order to simplify the illustration, Note 1 to entry: The explanation of the definition is given in Figures 1 and 3. In Note 2 to entry: Examples are presented in Figures 2 and 4 3.3 bassin 8 deviation outside the ideal geometrical shape of an edge defined by two tangent outside straight lines to the adjacent feature of the zone of the undefined edge Note 1 to entry: The explanation of the definition is given in Figures 5 and Z In order to simplify the illustration, only the passing and the two tangents outside straight lines are represented Note 2 to entry: a burr or a flash(see Figure 5) can be considered to be a special case of external passing Note 3 to entry: Examples are presented in Figures 6 and 8 ISo 2017-All rights reserved BS|So13715:2017 Iso13715:2017(E) Key 1 ideal sharp edge 2 undercut Figure 1- Undercut on an external edge Figure 2-Examples of undercut on an external edge 2 K 1 ideal sharp edge 2 undercut Figure 3- Undercut on an internal edge Figure 4- Examples of undercut on an internal edge o ISo 2017-All rights reserved
