Preparation of steel substrates before application of paints and related products - Tests for the assessment of surface cleanliness - Part 15: Extraction of soluble contaminants for analysis by acid extraction (ISO 8502-15:2020)
This document specifies a method of extracting, for analysis, acid soluble contaminants from a surface by use of flexible cells in the form of adhesive patches or sleeves which can be attached to any surface, regardless of its shape (flat or curved) and its orientation (facing in any direction, including downwards).
The described method is suitable for use in the field to determine the presence of acid soluble contaminants before painting or a similar treatment.
This document 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 such as ISO 8502-5.
This document is similar in procedure to, but not equal to, ISO 8502-6. The main difference is the solvent used and the subsequent analysis that can be performed on the extraction solution.
Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen - Prüfungen zum Beurteilen der Oberflächenreinheit - Teil 15: Extraktion von löslichen Verunreinigungen zur Analyse durch Säureextraktion (ISO 8502-15:2020)
Dieses Dokument legt ein Verfahren zum Lösen säurelöslicher Verunreinigungen auf einer Oberfläche zur Analyse fest, wobei verformbare Zellen in Form selbstklebender Pflaster oder Hülsen verwendet werden, die auf jede Oberfläche, unabhängig von deren Form (eben oder gekrümmt) und Ausrichtung (in jeder Richtung, auch nach unten), aufgebracht werden können.
Das beschriebene Verfahren ist als Feldverfahren geeignet, um das Vorhandensein säurelöslicher Verunreinigungen vor dem Beschichten oder einer ähnlichen Behandlung zu bestimmen.
Die anschließende Analyse der gelösten Verunreinigungen ist nicht Gegenstand dieses Dokuments. Analysenverfahren, die als Feldverfahren geeignet sind, werden in anderen Teilen von ISO 8502, wie z. B. ISO 8502 5, beschrieben.
Dieses Dokument und ISO 8502 6 sind im Hinblick auf das Verfahren ähnlich, aber nicht gleich. Der Hauptunterschied liegt im verwendeten Lösemittel und der anschließenden Analyse, die mit der Extraktionslösung erfolgen kann.

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.

ISO 8502-15:2020(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.
The ISO 8501, ISO 8502 and ISO 8503 series 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 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 t
