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 44, Welding and allied processes, Subcommittee
SC 5, Testing and inspection of welds.
This second edition cancels and replaces the first edition (ISO 17637:2003), which has been technically
revised.
Requests for official interpretations of any aspect of this International Standard should be directed to
the Secretariat of ISO/TC 44/SC 5 via your national standards body. A complete listing of these bodies

Non-destructive testing of welds — Visual testing of fusion-
welded joints
1 Scope
This document specifies the visual testing of fusion welds in metallic materials. It may also be applied
to visual testing of the joint prior to welding.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
No terms and definitions are listed in this document.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

4 Test conditions and equipment
The illuminance at the surface with white light shall be a minimum of 350 lx; wearing of tinted goggles
(e.g. protective sunglasses) increases the minimum illuminance. However, 500 lx is recommended.
For direct inspection, the access shall be sufficient to place the eye within 600 mm of the surface to be
examined and at an angle not less than 30° (see Figure 1).
a
Range.
Figure 1 — Access for testing
Remote inspection using mirrors, boroscopes, fibre optic cables or cameras shall be considered when
the access for testing in accordance with Figure 1 is not possible or when specified by an application
standard.
An additional light source can be used to increase the contrast and relief between imperfections and
the background.
ISO 17637:2016(E)
Where the result of visual testing is inconclusive, the visual test should be supplemented by other non-
destructive testing methods for surface inspections.
Examples of equipment used for visual testing are given in Annex A.
