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.
For an explanation on the meaning of ISO specific terms and 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 the following URL: www . i so .org/ iso/ foreword .html.
This document was developed by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee
SC 12, Preparation of steel substrates before application of paints and related products.
This second edition cancels and replaces the first edition (ISO 8502-3:1992), which has been technically
revised with the following changes:
a) in Clause 2 and 5.1, IEC 454-2 has been substituted with IEC 60454-2;
b) in Table 1, decimal sign has been changed to a decimal comma;
c) Figure A.4 has been added and the former Figure A.4 has been renamed Figure A.5;
d) the document has been editorially revised.
ISO 8502 consists of the following parts, under the general title Preparation of steel substrates before
application of paints and related products — Tests for the assessment of surface cleanliness:
— Part 2: Laboratory determination of chloride on cleaned surfaces
— Part 3: Assessment of dust on steel surfaces prepared for painting (pressure-sensitive tape method)
— Part 4: Guidance on the estimation of the probability of condensation prior to paint application
— Part 5: Measurement of chloride on steel surfaces prepared for painting (ion detection tube method)
— Part 6: Extraction of soluble contaminants for analysis — The Bresle method
— Part 9: Field method for the conductometric determination of water-soluble salts
— Part 11: Field method for the turbidimetric determination of water-soluble sulfate
— Part 12: Field method for the titrimetric determination of water-soluble ferrous ions

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 direct influence on
the choice of protective coating to be applied and on its performance. Such recommendations are found
in other documents such as n
