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.

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/

This document was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings,
in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/
TC 240, Thermal spraying and thermally sprayed coatings, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This first edition of ISO 14922 cancels and replaces ISO 14922-1:1999, ISO 14922-2:1999,
ISO 14922-3:1999 and ISO 14922-4:1999, which have been technically revised. The main changes
compared with the previous editions are as follows:
— the four parts have been consolidated into one document;
— the requirements for the manufacturer now correspond to those of the parts;
— the weighting of requirements with +++ / ++ / + have been updated and are now requirements;
— the requirements have been separated: the quality assurance requirements former classified in 1,
2, 3 now clear as QRC and QAL C, S, E, the three assessment groups as comprehensive requirements,
standard (normal) requirements, elementary requirements titled and presented in direct
comparison in three columns in Annex C;
— the dependence on ISO 9001 has been removed;
— decision on QAL C, S, E by customer or manufacturer itself.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Thermal spraying processes are widely applied for producing industrial products and are mainly
applied for preventive protection of surfaces. The application can take place both within the workshop
as well as on site. Measures for the maintenance of worn coatings or of surfaces on components are
also in the field of use. Thermal spraying can be found in all industries, but especially in the aerospace,
stationary gas turbine, automotive, machinery construction, printing and chemical, and oil extraction
and refining fluid control industries, as well as for medical purposes and for steel construction in the
field of off-shore and on-shore, etc. Usually coatings are applied for anticorrosive and/or anti-wear
purposes, high temperature protection and against chemical attack, as well as for aesthetic or electrical
reasons.
Thermal spraying belongs to the so-called "special processes", whe
