Fasteners — Parallel grooved pins, with chamfer point — Full-length diamond grooves

Fixations — Goupilles cannelées constantes, à bout chanfreiné — Cannelures diamant sur toute la longueur

La présente Norme internationale prescrit les caractéristiques des goupilles cannelées à chanfrein en acier ou en acier inoxydable austénitique, à trois cannelures constantes sur toute leur longueur, débouchantes d'un côté et régulièrement espacées, de diamètre nominal, d1, de 1,5 mm à 25 mm inclus. Le matériau refoulé de chaque côté des cannelures forme un renflement dont le diamètre d2, supérieur au diamètre nominal d1, permet un ajustement serré de ces goupilles cannelées lorsqu'elles sont emmanchées en force dans un trou de diamètre de perçage égal au diamètre nominal de la goupille d1 (voir article 4).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). 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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 8740:1997) which has been technically
revised.
The main changes are as follows:
— terms and definitions, principles for grooved pins and assembly (including hole dimensions), control of
the expanded diameter d and pin straightness, mechanical and physical properties (including shear
resistance and hardness) and inspection which are common for all grooved pins (product standards
ISO 8739 to ISO 8747, ISO 13670 and ISO 13672) have been specified in the new reference standard
ISO 13669;
— non-preferred diameters 1 mm, 3,5 mm, 7 mm, 9 mm, 14 mm and 18 mm have been added;
— values of expanded diameter d for steel pins have been slightly increased for the shortest length range,
and have been added for stainless steel pins;
— tolerances for the rounded end have been added, and chamfer end option has been deleted;
— stainless steel grades A2, A4, C1 and F1 have been added;
— other materials (such as hardened steels, brass, aluminium) are by agreement (see Table 3);
— specifications for labelling have been added as Clause 8.

Fasteners — Parallel grooved pins, with chamfer point — Full-
length diamond grooves
1 Scope
This document specifies the characteristics of parallel grooved pins with chamfer point and full-length
diamond grooves (with open ends), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm.
These grooved pins are designed to fulfil the main following function: locking together two or more parts,
with an easy installation (due to the chamfer point) and a highest level of pull-out resistance (due to the
elastic fit behaviour of the pin).
NOTE The general requirements (including functional principles for grooved pins and assembly) are specified in
ISO 13669.

Avant-propos
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 rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir
www.iso.org/directives).
L’ISO attire l’attention sur le fait que la mise en application du présent document peut entraîner l’utilisation
d’un ou de plusieurs brevets. L’ISO ne prend pas position quant à la preuve, à la validité et à l’applicabilité de
tout droit de propriété revendiqué à cet égard. À la date de publication du présent document, l’ISO n'avait pas
reçu notification qu’un ou plusieurs brevets pouvaient être nécessaires à sa mise en application. Toutefois,
il y a lieu d’avertir les responsables de la mise en application du présent document que des informations
plus récentes sont susceptibles de figurer dans la base de données de brevets, disponible à l'adresse
www.iso.org/brevets. L’ISO ne saurait être tenue pour responsable de ne pas avoir identifié tout ou partie de
tels droits de propriété.
Les appellations commerciales éventuellement mentionnées dans le présent document sont données pour
information, par souci de commodité, à l’intention des utilisateurs et ne sauraient constituer un engagement.
Pour une explication de la nature volontaire des normes, la signification des termes et expressions
spécifiques de l'ISO liés à l'évaluation de la conformité, ou pour toute information au sujet de l'adhésion de
l'ISO aux principes de l’Organisation mondiale du commerce (OMC) concernant les obstacles techniques au
commerce (OTC), voir le lien suivant: www.iso.org/iso/foreword.html.
Le présent document a été élaboré par le comité technique ISO/TC 2, Fixations, en collaboration avec le
comité technique CEN/TC 185, Fixations, du Comité européen de normalisation (CEN) conformément à
l’Accord de coopération technique entre l’ISO et le CEN (Accord de Vienne).
Cette troisième édition annule et remplace la deuxième édition (ISO 8740:1997) qui a fait l’objet d’une
révision technique.
Les principales modifications sont les suivantes:
— les termes et définitions, les principes d'utilisation des goupilles cannelées et leur assemblage (incluant
la dimension des trous), le contrôle du diamètre de renflement d et de la rectitude des goupilles, les
caractéristiques mécaniques et physiques (incluant la résistance au cisaillement et la dureté) et les
contrôles, communs à toutes les goupilles cannelées (normes de produits ISO 8739 à ISO 8747, ISO 13670
et ISO 13672) ont été spécifiés dans la nouvelle norme de référence ISO 13669;
— les diamètres non préférentiels 1 mm, 3,5 mm, 7 mm, 9 mm, 14 mm et 18 mm ont été ajoutés;
— les valeurs de diamètre de renflement d pour les goupilles en acier de la gamme de longueurs les plus
courtes ont été légèrement augmentées, et ont été ajoutées pour les goupilles en acier inoxydable;
— les tolérances pour les extrémités arrondies ont été ajoutées, et l’option pour les extrémités chanfreinées
a été supprimée;
— les grades d'acier inoxydables A2, A4, C1 et F1 ont été ajoutés;
— les autres matériaux (tels que les aciers traités thermiquement, le laiton, l'aluminium) sont par accord
(voir Tableau 3)
— les spécifications pour l'étiquetage ont été ajoutées à l'Article 8.

1 Domaine d’application
Le présent document spécifie les caractéristiques des goupilles cannelées constantes, à bout chanfreiné et
cannelures diamant sur toute la longueur (débouchantes), en acier et en acier inoxydable, et de diamètre
nominal 1 mm à 25 mm.
Ces goupilles cannelées sont conçues pour remplir la fonction principale suivante: solidarisation de deux ou
plusieurs pièces, avec une installation facile (du fait du bout chanfreiné) et une résistance à l'extraction au
plus haut niveau (du fait du comportement par ajustement élastique de la goupille dans son trou).
NOTE Les exigences générales (incluant les principes fonctionnels des goupilles cannelées et leur assemblage)
sont spécifiées dans l'ISO 13669.
