Metallic materials - Designation of test specimen axes in relation to product texture (ISO 3785:2006)
ISO 3785:2006 specifies a method for designating test specimen axes in relation to product texture by means of an X-Y-Z orthogonal coordinate system.
The system applies equally to unnotched and notched (or precracked) test specimens.
The method is intended only for metallic materials with uniform texture that can be unambiguously determined.
Metallische Werkstoffe - Kennzeichnung von Probenachsen in Bezug zur Halbzeuggefügetextur (ISO 3785:2006)
In dieser Internationalen Norm ist ein Verfahren zur Kennzeichnung von Probenachsen in Bezug zur Halbzeuggefügetextur mit Hilfe eines rechtwinkligen X-Y-Z-Koordinatensystems festgelegt.
Das System gilt gleichermaßen für ungekerbte und gekerbte (oder angerissene) Proben.
Das Verfahren ist nur für metallische Werkstoffe mit einheitlichem Gefüge vorgesehen, das eindeutig bestimmt werden kann.
Über die Orientierung der Probe wird vor deren Bearbeitung entschieden, sie wird in Übereinstimmung mit dem hier beschriebenen System, festgelegt in dieser Internationalen Norm festgelegt und aufgezeichnet.
Matériaux métalliques - Désignation des axes des éprouvettes en relation avec la texture du produit (ISO 3785:2006)
L'ISO 3785:2005 spécifie une méthode pour désigner les axes des éprouvettes en relation avec la texture du produit au moyen d'un système orthogonal de coordonnées X-Y-Z.
Le système s'applique aussi bien aux éprouvettes sans entaille et qu'aux éprouvettes entaillées (ou préfissurées).
La méthode est destinée seulement aux matériaux métalliques de texture uniforme qui peut être déterminée sans ambiguïté.

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 3785 was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee
SC 4, Toughness testing — Fracture (F), Pendulum (P), Tear (T).
This second edition cancels and replaces the first edition (ISO 3785:1976), which has been technically revised.

Introduction
The measured mechanical properties of a metallic product, especially those characterizing ductility and
toughness, such as elongation, reduction of area, fracture toughness and impact resistance, are dependent
on the test specimen location within the product and orientation with respect to the product's principal
directions of metal working, grain flow or otherwise-produced texture. This International Standard specifies a
method for designating specimen orientation in relation to product texture.
INTERNATIONAL STANDARD ISO 3785:2006(E)
Metallic materials — Designation of test specimen axes in
relation to product texture
1 Scope
This International Standard specifies a method for designating test specimen axes in relation to product
texture by means of an X-Y-Z orthogonal coordinate system.
The system applies equally to unnotched and notched (or precracked) test specimens.
The method is intended only for metallic materials with uniform texture that can be unambiguously determined.
Test specimen orientation is decided before specimen machining, identified in accordance with the
designation system specified in this International Standard, and recorded.
2 Designation system
2.1 General
The method for relating specimen axes to the characteristic directions of the product makes use of an X-Y-Z
orthogonal coordinate system for wrought metals:
⎯ the letter X always denotes the direction of principal deformation (maximum grain flow in the product);
⎯ the letter Y denotes the direction of least deformation;
⎯ the letter Z denotes the direction normal to the X-Y plane.
2.2 Exception — not aligned
When the specimen direction does not coincide with the product's characteristic grain-flow directions, two
letters are used as described for unnotched specimens in 3.2.2 and 3.2.4, and for notched specimens in 4.3.
2.3 Exception — no grain flow
When there is no grain-flow direction as in a casting,
