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).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the World

Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT)
see www.iso.org/iso/foreword.html.

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,

Subcommittee SC 5, Testing and inspection of welds.

This third edition cancels and replaces the second edition (ISO 5173:2009+Amd 1:2011) which has been

technically revised.
The main changes compared to the previous edition are as follows:

— scope updated to introduce guided transverse bend tests with a roller and longitudinal bend tests as

alternative methods of testing for heterogeneous assemblies ;
— in Clause 4, the testing temperature was removed;
— sub-clause 7.2.2 modified accordingly ;
— figures corrected

— standard content updated to meet ISO requirements (creation of Clause 2, modification of Clause 3)

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www.iso.org/members.html.

Destructive tests on welds in metallic materials — Bend tests
1 Scope

This document specifies a method for making transverse root, face and side bend tests on test specimens

taken from butt welds, butt welds with cladding (subdivided into welds in clad plates and clad welds)

and cladding without butt welds, in order to assess ductility and/or absence of imperfections on or near

the surface of the test specimen. It also gives the dimensions of the test specimen.

In addition, this document specifies methods to be used instead of transverse bend tests with a former

for heterogeneous joints when base materials, heat affected zones and/or weld metal have a significant

difference in their physical and mechanical properties in relation to bending. Guided transverse bend

tests with a roller and longitudinal bend tests are alternative methods of testing for heterogeneous

assemblies.

This document applies to metallic materials in all forms of product with welded joints made by any

welding process.
