Metallic materials - Designation of test specimen axes in relation to product texture (ISO 3785:2023)
This document specifies a method for designating test specimen axes in relation to product texture by means of an X-Y-Z orthogonal coordinate system.
This document applies equally to unnotched and notched (or precracked) test specimens.
This document 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 document, and recorded.
Metallische Werkstoffe - Kennzeichnung von Probenachsen in Bezug zur Halbzeuggefügetextur (ISO 3785:2023)
Dieses Dokument legt ein Verfahren zur Kennzeichnung von Probenachsen in Bezug zur Halbzeuggefügetextur mit Hilfe eines rechtwinkligen X-Y-Z-Koordinatensystems fest.
Dieses Dokument ist gleichermaßen anzuwenden für ungekerbte und gekerbte (oder angerissene) Proben.
Dieses Dokument 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 diesem Dokument, festgelegt und aufgezeichnet.
Matériaux métalliques - Désignation des axes des éprouvettes en relation avec la texture du produit (ISO 3785:2023)
Le présent document 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 présent document s'applique aussi bien aux éprouvettes sans entaille qu'aux éprouvettes entaillées (ou préfissurées).
Le présent document est destiné seulement aux matériaux métalliques de texture uniforme qui peut être déterminée sans ambiguïté.
L'orientation de l'éprouvette est décidée avant usinage de l'éprouvette, identifiée conformément au système de désignation spécifié dans le présent document, et enregistrée.
Kovinski materiali - Označevanje osi preskusnih vzorcev glede na teksturo snovi vzorca (ISO 3785:2023)
Ta dokument določa metodo za označevanje osi preskusnih vzorcev glede na teksturo snovi vzorca s pravokotnim koordinatnim sistemom X-Y-Z.
Ta dokument se uporablja tako za nezarezane kot za zarezane (ali z umetno razpoko) preskusne vzorce.
Ta dokument se uporablja samo za kovinske materiale z enotno teksturo, ki jo je mogoče nedvoumno določiti.
Smer preskusnih vzorcev je določena pred obdelavo vzorcev, identificirana v skladu s sistemom označevanja, navedenega v tem dokumentu, in zabeležena.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
