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.
Préparation des subjectiles d'acier avant application de peintures et de produits assimilés - Essais pour apprécier la propreté d'une surface - Partie 9: Méthode in situ pour la détermination des sels solubles dans l'eau par conductimétrie (ISO 8502-9:2020)
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.
