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 8504-1:2019(E)
Introduction
The performance of protective coatings of paint and related products applied to steel is significantly
affected by the state of the steel surface immediately prior to painting. The principal factors that are
known to influence this performance are
— the presence of rust and mill scale,
— the presence of surface contaminants, including salts, dust, oils and greases, and
— the surface profile.
The ISO 8501 series, the ISO 8502 series and the ISO 8503 series provide methods for assessing these
factors, while the ISO 8504 series provides guidance on the preparation methods that are available for
cleaning steel substrates, indicating the capabilities of each of attaining specified levels of cleanliness.
These International Standards do not contain recommendations for the protective coating system to be
applied to the steel surface. They do not contain recommendations on surface quality requirements for
specific situations even though surface quality can have a direct influence on the choice of protective
coating and on its performance. Such recommendations are found in other documents such as national
standards and codes of practice. These International Standards are used to ensure that the specified
qualities are
— compatible and appropriate both for the environmental conditions to which the steel will be exposed
and for the protective coating system to be used, and
— within the capability of the cleaning procedure specified.
This document should be read in conjunction with ISO 8504-2, ISO 8504-3 that describe specific surface
preparation methods.
