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).

ISO 14232-1:2017(E)
Introduction
For thermal spray processes that use material in a powder form, the powder can be considered as one
of the main elements requiring control to produce an acceptable coating. The chemical and physical
properties of powder play a fundamental role in the creation of desired coating properties. The size,
shape and morphology of the powder particles determine the melting behaviour and therefore the
processing of powders in general.
To keep the coating properties and the spray process as consistent as possible, it is very important to
maintain all the characteristics of powder particles within limited tolerances.
An exception is granted to details on the properties of sprayed coatings. Such properties, which result
from spraying conditions not covered by this document, e.g. gas composition, deposition efficiency,
material flow rate, stand-off distance, etc., can differ greatly from the properties of the original powder.
The ISO 14232 series consists of two parts. This document examines the characterization of spray
powders. ISO/TR 14232-2 is a technical report that examines how technical literature describes the
application of powders.
