Preparation of steel substrates before application of paints and related products - Tests for the assessment of surface cleanliness - Part 9: Field method for the conductometric determination of water-soluble salts (ISO 8502-9:2020)
This document specifies a field method for the assessment of the surface density of various water-soluble salts on steel surfaces, before and/or after surface preparation, by conductometric determination. The individual surface densities of the salt composition like chlorides, sulphates, sodium, etc, cannot be determined by this method.
This method assesses only contaminants that forms an electrolyte (ions) when in contact with water. These represent the greater part of the contaminants.
Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen - Prüfungen zum Beurteilen der Oberflächenreinheit - Teil 9: Feldverfahren zur Bestimmung von wasserlöslichen Salzen durch Leitfähigkeitsmessung (ISO 8502-9:2020)
Dieses Dokument legt ein Feldverfahren zum Bestimmen der Oberflächendichte verschiedener wasserlöslicher Salze auf Stahloberflächen durch konduktometrische Bestimmung vor und/oder nach der Oberflächen¬vorbereitung fest. Die einzelnen Oberflächendichten der Salzzusammensetzung von Chloriden, Sulfaten, Natrium usw. können nach diesem Verfahren nicht bestimmt werden.
Dieses Verfahren erfasst nur Verunreinigungen, die einen Elektrolyten (Ionen) bilden, wenn sie mit Wasser in Kontakt kommen. Diese stellen den größeren Teil der Verunreinigungen dar.

Le présent document spécifie une méthode in situ permettant d'évaluer par conductimétrie la concentration des différents sels solubles dans l'eau sur les subjectiles d'acier avant et/ou après la préparation de surface. Les densités de surface individuelles des composés salés tels que les chlorures, les sulfates, le sodium, etc. ne peuvent pas être déterminées par cette méthode.
La méthode n'évalue que les contaminants qui forment un électrolyte (ions) au contact de l'eau. Ceux-ci représentent la majeure partie de la contamination.

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 of the voluntary nature of standards, 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 www .iso .org/

This document 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, in collaboration

Agreement).
This second edition cancels and replaces the first edition (ISO 8502-9:1998), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— inclusion of new measurement methods according to the direct sample method;
— improved connection to ISO 850
