Technical product documentation - Edges of undefined shape - Indication and dimensioning

ISO 13715:2017 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 specified. In cases where the geometrically defined shape of an edge (for example, 1 × 45°) is required, the general dimensioning principles given in ISO 129‑1 apply.

Overview

ISO 13715:2017 - Technical product documentation - Edges of undefined shape - Indication and dimensioning - specifies standardized rules for indicating and dimensioning edges that are not geometrically defined on the nominal model. The standard defines the graphical symbol, its proportions (Annex A), how to show size and direction limits, and conventions for individual, limited-area and general indications on engineering drawings. It also clarifies when to use ISO 129‑1 principles for geometrically defined edges (for example, 1 × 45°).

Keywords: ISO 13715:2017, edges of undefined shape, technical product documentation, edge indication, dimensioning, graphical symbols.

Key topics and technical requirements

  • Scope and purpose: Controls deviations at edges that cannot be expressed by ideal geometry - e.g., undercut (material removed) and passing (excess material such as burrs or flash).
  • Basic graphical indication: A standardized symbol (with proportions given in Annex A) must be readable from the bottom of the drawing. Additional information is placed in defined symbol areas.
  • Type indication: Use symbol elements + (plus) for permitted passing, − (minus) for required undercut, or ± when both directions are allowed (± requires size specification).
  • Size/dimensioning: Maximum deviations are indicated numerically after the symbol element. Single positive or negative limits imply the other limit is zero; two limits may be shown as upper/lower deviations.
  • Direction and asymmetry: Rules for indicating direction of passing or undercut (single-direction and asymmetrical indications). Direction cannot be specified for non‑90° angles.
  • Location conventions: Symbols may be applied individually (to a line or point), to limited areas (long-dashed-dotted line per ISO 128‑24), or generally for all edges (placed near title block or notes).
  • Illustrative guidance: Annex B provides examples; figures in Clause 4 show application scenarios and terminology (undercut, passing, sharp edge).

Related references in the text: ISO 129‑1 (general dimensioning), ISO 128‑22, ISO 128‑24, ISO 1101.

Practical applications and users

ISO 13715:2017 is used to:

  • Communicate required edge conditions on mechanical and product drawings.
  • Specify acceptable burrs, flashes, undercuts and passes for manufacturing and inspection.
  • Harmonize drawing interpretation between design, manufacturing, and quality control.

Primary users:

  • Mechanical design engineers and CAD drafters
  • Manufacturing engineers and machinists
  • Quality inspectors and metrology labs
  • Technical illustrators and standards coordinators

Related standards

  • ISO 129‑1 - General dimensioning principles (for geometrically defined edges)
  • ISO 128‑22 / ISO 128‑24 - Line types and drawing conventions
  • ISO 1101 - Geometrical product specifications (used for “between” symbols)

Using ISO 13715 improves clarity of engineering drawings, reduces manufacturing errors related to edge conditions, and supports consistent quality inspection.

Introduction
In technical drawings, the ideal geometric shape is represented without any deviation and, in general,
without consideration of the conditions of the edges. 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.

L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes
nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est
en général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l’ISO participent également aux travaux.
L’ISO collabore étroitement avec la Commission électrotechnique internationale (IEC) en ce qui
concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1 Il convient, en particulier, de prendre note des différents
critères d’approbation requis pour les différents types de documents ISO. Le présent document a été

Introduction
Dans les dessins techniques, la forme géométrique parfaite est représentée sans aucun écart et en
général sans considération des conditions des arêtes. Cependant, pour de nombreuses raisons (par
exemple fonctionnement d’une pièce, sécurité), un état particulier des arêtes est exigé, par exemple
arêtes extérieures sans bavure ou avec bavure de dimension limitée, et arêtes intérieures avec
raccordement.
Le présent document fournit une symbologie pour l’indication de l’arête souhaitée.

principes généraux de cotation établis dans l’ISO 129-1 s’appliquent.

3.1
arête de forme non définie
ligne de transition, comprise dans un plan d’intersection, qui n’est pas définie sur le modèle nominal et
qui existe entre deux surfaces intégrales adjacentes
3.2
dégagement
écart en retrait par rapport à la forme géométrique idéale d’une arête, définie par deux droites
extérieures tangentes à l’élément adjacent de la zone de l’arête non définie
Note 1 à l’article: L’explication de la définition est donnée aux Figures 1 et 3. Pour simplifier l’illustration, seuls le
dégagement et les deux droites tangentes extérieures sont représentés.
Note 2 à l’article: Pour des exemples, voir Figures 2 et 4.
3.3
raccordement
écart en relief par rapport à la forme géométrique idéale d’une arête, définie par deux droites extérieures
tangentes à l’élément adjacent de la zone de l’arête non définie
Note 1 à l’article: L’explication de la définition est donnée aux Figures 5 et 7. Pour simplifier l’illustration, seuls le
raccordement et les deux droites tangentes extérieures sont représentés.
Note 2 à l’article: Une bavure ou ébarbure (voir Figure 5) peut être considérée comme étant un cas particulier de
raccordement extérieur.
Note 3 à l’article: Pour des exemples, voir Figures 6 et 8.

4 Indications sur les dessins
4.1 Indication de base
Les exigences relatives à une arête de pièce doivent être indiquées par l’indication graphique de base
illustrée à la Figure 9. Si toutes les arêtes d’une pièce doivent être spécifiées comme «non définies»,
l’indication générale de base est utilisée (voir Figure 10).
Le symbole graphique ainsi que la spécification doivent être indiqués de façon à pouvoir être lus de bas
en haut du dessin.
Les proportions de ce symbole sont données dans l’Annexe A. Des indications complémentaires peuvent
être placées dans les zones a , a ou a (voir Figure A.1).
1 2 3
Des arêtes non définies ne peuvent pas être décrites par le seul élément symbole de base. Comme
indication minimale, le type d’arête non définie doit être spécifié.

4.2 Types d’arête non définie
Le type d’une arête non définie doit être inscrit dans la zone a (voir Figure A.1), à l’intérieur du
symbole de base. L’élément symbole + (plus) ou – (moins) ou ± (plus ou moins) est utilisé conformément
au Tableau 1.
L’élément symbole + (plus) indique l’acceptation d’un excès de matière, c’est-à-dire un raccordement.
L’élément symbole – (moins) indique l’exigence d’un retrait de matière, c’est-à-dire un dégagement.
L’élément symbole ± (plus ou moins) indique l’acceptation d’un excès ou d’un retrait de matière, c’est-
à-dire un dégagement ou un raccordement. Celui-ci ne peut être utilisé qu’avec une indication de taille

記事のタイトル: ISO 13715:2017 - 技術製品の文書化 - 未定義のエッジの指示と寸法 記事の内容: ISO 13715:2017は、技術製品の文書化における未定義のエッジの指示と寸法に関する規則を定めています。使用するグラフィカルシンボルの比率と寸法も指定されています。エッジの幾何学的に定義された形状(例:1 × 45°)が必要な場合は、ISO 129-1で定められた一般的な寸法設定原則に従う必要があります。

ISO 13715:2017 is a standard that provides guidelines for indicating and dimensioning undefined edges in technical product documentation. It also specifies the proportions and dimensions of the graphical symbols to be used. When a geometrically defined shape of an edge is needed, the general dimensioning principles given in ISO 129-1 should be followed.
