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.

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 10, Quality management in the field of welding.
This first edition cancels and replaces the fours edition of ISO/TR 15608:2017, which has been changed into
an International standard and contains the following changes:
a) change from Technical Report to International Standard;
b) change title.

Welding — Grouping system for metallic materials
1 Scope
This document specifies a uniform system for grouping materials for welding purposes. It can also be applied
for other purposes, such as heat treatment, forming and non-destructive testing.
It covers grouping systems for the following standardized materials:
— steels;
— aluminium and its alloys;
— copper and its alloys;
— nickel and its alloys;
— titanium and its alloys;
— zirconium and its alloys;
— cast irons.
2 Normative references
