Grooved pins - One-third-length centre grooved (ISO 8742:1997)

Knebelkerbstifte mit kurzen Kerben (ISO 8742:1997)

Diese Internationale Norm beschreibt die Eigenschaften von Knebelkerbstiften aus Stahl oder austenitischem nichtrostendem Stahl, mit kurzen Kerben, mit drei gleichmäßig verteilten Längskerben auf der Außenfläche. Die Kerbstifte haben einen Nenndurchmesser d1, von 1,5 mm bis einschließlich 25 mm. Der zu jeder Seite der Kerbe verdrängte Werkstoff, der den aufgeweiterten Durchmesser d2 bildet, welcher größer als dder Nenndurchmesser d1 ist, führt zu einer kraftschlüssigen Verbindung, wenn diese Kerbstifte in eine Bohrung mit einem Durchmesser gleich dem Nenndurchmesser d1 gepreßt werden

Goupilles cannelées à cannelures centrales constantes sur le tiers de la longueur non débouchantes (ISO 8742:1997)

La présente Norme internationale prescrit les caractéristiques des goupilles cannelées en acier ou en acier inoxydable austénitique, à trois cannelures centrales constantes sur le tiers de leur longueur, non débouchantes 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.
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.
International Standard ISO 8742 was prepared by Technical Committee
ISO/TC 2, Fasteners.
This second edition cancels and replaces the first edition (ISO 8742:1986),
which has been technically revised.

INTERNATIONAL STANDARD  ISO ISO 8742:1997(E)
Grooved pins — One-third-length centre grooved
1 Scope
This International Standard specifies the characteristics of one-third-length centre grooved pins made of steel
or austenitic stainless steel which have three equally spaced grooves impressed longitudinally on their
exterior surface, with nominal diameter, d , from 1,5 mm to 25 mm inclusive.
The displaced material to each side of the grooves forming an expanded diameter, d , which is larger than the
nominal diameter d will cause a non-positive locking fit when these grooved pins are forced into a drilled hole
equal to the nominal diameter d (see clause 4).
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject
to revision, and parties to agreements based on this International Standard are encouraged to investigate the
