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 on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 44, Welding and allied processes, Subcommittee
SC 5, Testing and inspection of welds.
This second edition cancels and replaces the first edition (ISO 17643:2005), which has been
technically revised.

INTERNATIONAL STANDARD ISO 17643:2015(E)
Non-destructive testing of welds — Eddy current testing of
welds by complex-plane analysis
1 Scope
This International Standard defines eddy current testing techniques for detection of surface breaking
and near surface planar discontinuities, mainly in ferritic materials (weld material, heat-affected zones,
base material).
Eddy current testing can also be specified for use with non-ferritic materials, for example in an
application standard.
The techniques can be applied to coated and uncoated objects during fabrication and in service, both
onshore and offshore.
Eddy current testing can be carried out on all accessible surfaces and on welds of almost any
configuration.
Unless otherwise specified at specific items in this International Standard, the general principles of
ISO 15549 apply.
NOTE Eddy current testing is usually performed in the as-welded condition. However, the accuracy of the
results can be affected by very rough surface finishes.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated

Non-destructive testing shall be performed by qualified and capable personnel. It is recommended that
personnel are qualified in accordance with ISO 9712 or an equivalent standard at an appropriate level
in the relevant industry sector.
