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 third edition cancels and replaces the first edition (ISO 3785:2006), 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.

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.
