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 collab-
orates 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 1119 was prepared by the Technical Committee
ISO/TC 213, Dimensional and geometrical product specifications and
verification.
This second edition cancels and replaces the first edition (ISO 1119:1975),
of which the tables have been corrected and updated, but not technically
modified.
Annexes A and B of this International Standard are for information only.

Introduction
This International Standard is a geometrical product specification (GPS)
standard and is to be regarded as a general GPS standard (see
ISO/TR 14638). It influences chain links 1 and 2 of the chain of standards
on angle.
For more detailed information of the relation of this International Standard
to other standards and the GPS matrix model, see annex A.

INTERNATIONAL STANDARD ISO ISO 1119:1998(E)
Geometrical Product Specifications (GPS) — Series
of conical tapers and taper angles
1 Scope
This International Standard gives a series of cones or conical tapers, ranging from 120° to less than 1°, or ratios
from 1:0,289 to 1:500, intended for general use in mechanical engineering.
It applies only to plain conical surfaces, and excludes prismatic pieces, taper threads, bevel gears, etc.
The method of dimensioning and tolerancing conical surfaces on drawings is covered in ISO 3040.
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
possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.
ISO 3:1973, Preferred numbers — Series of preferred numbers.
ISO 3040:1990, Technical drawings — Dimensioning and tolerancing — Cones.

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 (CEI) en
ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques
sont soumis aux comités membres pour vote. Leur publication comme
Normes internationales requiert l'approbation de 75 % au moins des
comités membres votants.
La Norme internationale ISO 1119 a été élaborée par le comité technique
ISO/TC 213, Spécifications et vérification dimensionnelles et géométriques
des produits.
Cette deuxième édition annule et remplace la première édition
(ISO 1119:1975), dont les tableaux ont été corrigés et mis à jour, mais elle
n'a pas été techniquement modifiée.
Les annexes A et B de la présente Norme internationale sont données
uniquement à titre d’information.

Spécification géométrique des produits (GPS) — Séries
d'angles de cônes et de conicités
1 Domaine d’application
La présente Norme internationale donne des séries d'angles de cônes allant de 120° à moins de 1° et de conicités
allant de 1:0,289 à 1:500, à l'usage de la mécanique en général.
Elle s'applique seulement aux cônes lisses et non aux pièces prismatiques, filetages coniques, engrenages
coniques, etc.
La cotation et le tolérancement des surfaces coniques lisses sur les dessins font l'objet de l'ISO 3040.
2 Références normatives
Les normes suivantes contiennent des dispositions qui, par suite de la référence qui en est faite, constituent des
dispositions valables pour la présente Norme internationale. Au moment de la publication, les éditions indiquées
étaient en vigueur. Toute norme est sujette à révision et les parties prenantes des accords fondés sur la présente
Norme internationale sont invitées à rechercher la possibilité d'appliquer les éditions les plus récentes des normes
indiquées ci-après. Les membres de la CEI et de l'ISO possèdent le registre des Normes internationales en vigueur
à un moment donné.

4 Valeurs
Les séries 1 et 2 spécifiées dans le tableau 1 doivent être utilisées, de préférence, dans cet ordre, en vue de
diminuer les gammes d'outils, de calibres et d'instruments de mesure nécessaires à la fabrication des pièces
coniques.
Le tableau 2 ne doit être utilisé que pour les applications particulières mentionnées dans la dernière colonne.
Ces tableaux donnent les valeurs calculées des angles de cônes ou des conicités, en vue de faciliter la conception,
la fabrication et le contrôle des pièces coniques.
