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 2538 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 2538:1974),
of which the tables have been corrected and updated, but not technically
modified.

INTERNATIONAL STANDARD  ISO ISO 2538:1998(E)
Geometrical Product Specifications (GPS) — Series of
angles and slopes on prisms
1  Scope
This International Standard specifies two series of prism angles from 120° to 0° 30' and a series of prism slopes
from 1:10 to 1:500, for general mechanical engineering purposes.
2  Definitions
For the purposes of this International Standard, the following definitions apply.
2.1
prism
part of a piece which is limited by two intersecting planes
See figure 1.
NOTE — Both planes are termed "prism planes". When these are intended for fits, they are termed "mating planes for the prism".
2.2
multiple prism
part of a piece which is limited by several pairs of intersecting planes
See figure 2.
NOTES
1  A double prism is limited by two pairs of intersecting planes.
2  When the intersection of each pair of planes is a point, the multiple prism is a pyramid (see figure 3).
2.3

2.4

dovetail
typical prism with a large angle
NOTE — These special prisms are used, for example, as a slideway on machine tools (see figures 4 and 5).

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 2538 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 2538:1974), 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.
