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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 8503-4 was prepared 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 8503-4:1988), which has been editorially revised
to improve the clarity.
ISO 8503 consists of the following parts, under the general title Preparation of steel substrates before application
of paints and related products — Surface roughness characteristics of blast-cleaned steel substrates:
— Part 1: Specifications and definitions for ISO surface profile comparators for the assessment of abrasive
blast-cleaned surfaces
— Part 2: Method for the grading of surface profile of abrasive blast-cleaned steel — Comparator procedure
— Part 3: Method for the calibration of ISO surface profile comparators and for the determination of surface
profile — Focusing microscope procedure
— Part 4: Method for the calibration of ISO surface profile comparators and for the determination of surface
profile — Stylus instrument procedure
— Part 5: Replica tape method for the determination of the surface profile

ISO 8503-4:2012(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:
a) the presence of rust and mill scale;
b) the presence of surface contaminants, including salts, dust, oils and greases;
c) the surface profile.
International Standards ISO 8501 (all parts), ISO 8502 (all parts) and ISO 8503 (all parts) have been prepared
to provide methods of assessing these factors, while ISO 8504 (all parts) provides guidance on the preparation
methods which are available for cleaning steel substrates, indicating the capabilities of each in attaining
specified levels of cleanliness.
These International Standards do not contain provisions for the protective coating systems to be applied to the
steel surface or for the surface quality provisions 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 provisions are
found in other documents, such as national standards and codes of practice.
It is necessary for the users of these International Standards to ensure that the qualities specified are:
— compatible and appropriate both for the environmental conditions to which the steel is exposed and for the
protective coating system to be used;
— within the capability of the cleaning procedure specified.
The four International Standards referred to above deal with the following aspects of preparation of steel substrates:
— ISO 8501: Visual assessment of surface cleanliness;
— ISO 8502: Tests for the assessment of surface cleanliness;
— ISO 8503: Surface roughness characteristics of blast-cleaned steel substrates;
— ISO 8504: Surface preparation methods.
