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).

This second edition cancels and replaces the first edition (ISO 8502-4:1993), which has been technically
revised with the following changes:
a) normative references have been updated;
b) mercury thermometer has been replaced by thermometer in Clause 4 a);
c) additional information is given in the note to Clause 4 b);
d) combined instrument described in Clause 4 d);
e) notes on instrument properties have been added in Clause 4;
f) in 5.2, “at a given atmospheric pressure” has been added to read “Their parameters are air
temperature and relative humidity at a given atmospheric pressure”;
g) in 5.3, it has been added that non-contact thermometers should not be used;
h) 5.4 has been changed to account for the definition of high and low risk of condensation given in
Clause 3;
i) description of the procedure with combined instruments has been added in 5.5.
j) a reference to the formula used in Annex A has been added.

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 as follows:
a) presence of rust and mill scale;
b) presence of surface contaminants, including salts, dust, oils and greases;
c) surface profile.
The ISO 8501, ISO 8502 and ISO 8503 series of International Standards have been prepared to provide
methods of 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 in attaining
specified levels of cleanliness.
These series of International Standards do not contain recommendations for the protective coating
systems to be applied to the steel surface. Neither do they contain recommendations for the surface
quality requirements for specific situations even though surface quality can have a d
