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 World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.
The committee responsible for this document is ISO/TC 135, Non-destructive testing, Subcommittee
SC 2, Surface methods.
This third edition cancels and replaces the second edition (ISO 9934-1:2015), of which it constitutes a
minor revision, with the modification for clarity of Clause 13 and other editorial improvements.

INTERNATIONAL STANDARD ISO 9934-1:2016(E)
Non-destructive testing — Magnetic particle testing —
Part 1:
General principles
1 Scope
This document specifies general principles for the magnetic particle testing of ferromagnetic materials.
Magnetic particle testing is primarily applicable to the detection of surface-breaking discontinuities,
particularly cracks. It can also detect discontinuities just below the surface but its sensitivity diminishes
rapidly with depth.
This document specifies the surface preparation of the part to be tested, magnetization techniques,
requirements and application of the detection media, and the recording and interpretation of results.
Acceptance criteria are not defined. Additional requirements for the magnetic particle testing of
particular items are defined in product standards (see the relevant International Standards or
European standards).
