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, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 121, Welding and allied processes, in accordance
with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 10675-1:2016), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— new Table 1 added with abbreviations;
— old Table 1 has been split into Table 2 and Table 3;
— in Table 4 (former Table 2), acceptance levels for maximum permissible pore sizes of porosity,
clustered porosity, linear porosity and for lack of fusion have been added;
— the acceptance levels in Clause 6 have been extended (General and tables);
— the captures of Figure B.1 to B.9 have been revised to conform with ISO 5817:2014;
— Figures C.1 and C.2 and the text have been revised to conform with ISO 5817:2014;
— the document has been editorially revised.

INTERNATIONAL STANDARD ISO 10675-1:2021(E)
Non-destructive testing of welds — Acceptance levels for
radiographic testing —
Part 1:
Steel, nickel, titanium and their alloys
1 Scope
This document specifies acceptance levels for indications from imperfections in butt welds of steel,
nickel, titanium and their alloys detected by radiographic testing. If agreed, the acceptance levels can
be applied to other types of welds (such as fillet welds, etc.) or materials.
The acceptance levels can be related to welding standards, application standards, specifications or
codes. This document assumes that the radiographic testing has been carried out in accordance with
ISO 17636-1 for RT-F (F = film) or ISO 17636-2 for RT-S (S = radioscopy) and RT-D (D = digital detectors).
