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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 7465 was prepared by Technical Committee ISO/TC 178, Lifts, escalators and moving walks.
This fourth edition cancels and replaces the third edition (ISO 7465:2001), which has been technically revised.

5 Manufacture and materials
Guide rails may be cold drawn or machined. In this International Standard, the manufacturing process for
each type of guide is indicated by the symbol /A for “cold drawn”, the symbol /B for “machined”, and the
symbol /BE for “machined high quality”.
2
The tensile strength of the raw material used (steel) shall be at least 370 N/mm and not more than
2
520 N/mm . For this purpose, it is recommended to use steel grade E 235 B for cold-drawn guide rails and
steel grade E 275 B for machined guides, in accordance with ISO 630:1995.
6 Guide rails
6.1 Designation
Guide rails complying with the requirements of this International Standard shall be designated as follows:
⎯ 1st element: Number of this International Standard, followed by a hyphen: ISO 7465-;
⎯ 2nd element: Guide rail shape: T;

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 Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. 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.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
L'ISO 7465 a été élaborée par le comité technique ISO/TC 178, Ascenseurs, escaliers mécaniques et trottoirs
roulants.
Cette quatrième édition annule et remplace la troisième édition (ISO 7465:2001), qui a fait l’objet d’une
révision technique.

5 Fabrication et matériaux
Les guides peuvent être étirés ou usinés. Dans la présente Norme internationale, le mode de fabrication est
précisé pour chaque type de guide, le symbole /A signifiant «étiré», le symbole /B «usiné», et le symbole /BE
«usiné haute performance».
2
La résistance de la matière première utilisée (acier) doit être au moins égale à 370 N/mm et, au plus, à
2
520 N/mm . À cette fin, il est recommandé d'utiliser la nuance d'acier E 235 B pour les guides étirés et la
nuance d'acier E 275 B pour les guides usinés, conformément à l'ISO 630:1995.

6.2 Caractéristiques et tolérances dimensionnelles
6.2.1 Longueur
La longueur du guide doit être indiquée en millimètres, avec une tolérance de ± 2 mm. Il est recommandé de
fournir des barres de 5 000 mm de long.
6.2.2 Dimensions
Voir Tableaux 2 à 7.
Deux séries de dimensions sont proposées:
⎯ Dimensions préférentielles dont les désignations sont données sans parenthèses.
EXEMPLE T82/A.
⎯ Dimensions non préférentielles dont les désignations sont données entre parenthèses.
EXEMPLE (T89/A).
Des guides de dimensions différentes peuvent être fournis après accord particulier entre le fabricant et
l'utilisateur.
