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 11, Qualification requirements for welding and allied processes personnel, 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 13585:2021), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— brazing processes, in accordance with ISO 4063:2023 , covered by this document, have been moved to
the scope;
— Clause 3 has been updated and additional terms have been defined;
— additional symbols and abbreviated terms have been added to Clause 4;
— Clause 5 has been significantly revised and updated including clarifications on brazing operator
qualification;
— material grouping has been moved to new Annex E;
— Clause 6 has been updated to refer to ISO or technically equivalent standards;
— the period of validity and prolongation of qualifications has been revised to 5 years in Clause 9.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

NOTE There can be other variables that the manufacturer deems to be essential in certain applications, e.g.
constraint on access for the torch, purging gas, etc., which need separate qualification. Examples are given in Annex D .

ISO/DIS 13585:2026(en)
The brazer or brazing operator who undertakes the brazing procedure test satisfactorily in accordance with
this document is qualified provided that the relevant testing requirements of this document are met.
5.2  Brazing process
Each qualification test qualifies only one brazing process listed in Clause 1. A change of brazing process
requires a new qualification test.
For furnace brazing the furnace atmosphere is limited to the same type of atmosphere, e.g. reducing or inert,
carburizing or decarburizing, and hydrogen or disassociated ammonia, as used in the test.
For brazing processes where fuel gases apply, the qualification shall be limited to the same type of fuel gas
and flame as used in the test.
