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.

thermal spraying
TS
process in which surfacing materials are heated to the plastic or molten state, inside or outside of the
spraying gun/torch, and then propelled onto a prepared surface
Note 1 to entry: The substrate may undergo some localized surface melting in the particle impact area only.
Note 2 to entry: To obtain specific properties of the deposit, a subsequent thermal, mechanical or sealing
treatment may be used.

4.2 Classification according to the operation
4.2.1 Manual spraying
All operations typical of the spraying process are manual.
4.2.2 Mechanized spraying
All operations typical of the spraying process are mechanized.
4.2.3 Automatic spraying
All operations typical of the spraying process are fully mechanized including all handling, e.g. work-
piece loading and unloading, and are integrated in a programmed system. Also, monitoring and
controlling of the entire spraying process can be included according to the closed loop method.
