Preparation of steel substrates before application of paints and related products - Tests for the assessment of surface cleanliness - Part 6: Extraction of soluble contaminants for analysis - The Bresle method (ISO 8502-6:2006)
ISO 8502-6:2006 describes a method of extracting, for analysis, soluble contaminants from a surface by use of flexible cells in the form of adhesive patches which can be attached to any surface, regardless of its shape (flat or curved) and its orientation (facing in any direction, including downwards).
The method described is suitable for use in the field to determine the presence of soluble contaminants before painting or a similar treatment.
This part of ISO 8502 does not cover the subsequent analysis of the contaminants that have been dissolved off. Methods of analysis suitable for field use are described in other parts of ISO 8502.
Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen - Prüfungen zum Bewerten der Oberflächenreinheit - Teil 6: Lösen von wasserlöslichen Verunreinigungen zur Analyse; Bresle-Verfahren (ISO 8502-6:2006)
Dieser Teil von ISO 8502 beschreibt ein Verfahren zum Lösen von löslichen Verunreinigungen auf einer Oberfläche zur Analyse, bei dem flexible Zellen in Form von selbstklebenden Pflastern verwendet werden, die auf jede Oberfläche, unabhängig von deren Form (eben oder gekrümmt) und Lage (in jeder Richtung, auch nach unten) geklebt werden können.
Das Verfahren ist als Feldverfahren geeignet, um lösliche Verunreinigungen vor dem Beschichten oder ähnlichen Behandlungen zu bestimmen.
Dieser Teil von ISO 8502 befasst sich nicht mit der Analyse der gelösten Verunreinigungen. Analysenverfahren, die als Feldverfahren geeignet sind, werden in anderen Teilen von ISO 8502 beschrieben.

L'ISO 8502-6:2006 spécifie une méthode pour l'extraction, en vue de l'analyse, des contaminants solubles sur une surface, en utilisant des cellules souples sous forme de pastilles adhésives qui peuvent être fixées sur toute surface, sans se soucier de sa forme (plate ou courbe) et de son orientation (face à toutes les directions, y compris vers le bas).
La méthode décrite convient pour l'emploi in situ en vue de déterminer la présence de contaminants solubles avant de peindre ou d'effectuer un traitement similaire.
L'ISO 8502-6:2006 ne traite pas de l'analyse consécutive des contaminants qui ont été dissous. Les méthodes d'analyse appropriées à l'emploi in situ sont décrites dans d'autres parties de l'ISO 8502.

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 8502-6 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 12,

ISO 8502-6:2006(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, ISO 8502 and ISO 8503 have been prepared to provide methods of
assessing these factors, while ISO 8504 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 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 national
standards and codes of practice. It will be 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 will be 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.
Each of these International Standards is in turn divided into separate parts.
This is one of a number of parts of ISO 8502 that specify tests for the assessment of surface cleanliness. In
connection with such tests, there are several methods for the extraction, for analysis, of soluble contaminants
on surfaces to be painted. Some of these methods are based on the swabbing of comparatively large test
surfaces. This technique provides average values of the contamination present, but it might conceal localized
concentrations of contaminants. Also, swabbing might not ensure sufficient penetration to dissolve all of the
deep-seated contamination such as ferrous salts.
There are other methods, however, which use small cells for the liquid used to remove and collect the surface
contaminants. The cells (rigid or flexible) are attached to test surfaces where soluble contaminants could be
expected, e.g. where pitting has occurred. This technique usually provides more accurate, point values of the
contamination present.
This part of ISO 8502 describes a simple, inexpensive field test using flexible cells in the form of adhesive
patches designed to be filled with solvent. The method was originally developed by a Swedish scientist,
Dr. A. Bresle.
