Preparation of steel substrates before application of paints and related products - Test methods for non-metallic blast-cleaning abrasives - Part 8: Field determination of water-soluble chlorides (ISO 11127-8:2020)
This document specifies a field method for the determination of water-soluble chlorides in non-metallic blast-cleaning abrasives. This field method is provided as a kit with all components and premeasured extraction solution.
This document differs from ISO 11127-7 in that equal volumes of the sample of abrasive and extraction solution are used for the determination of chloride level in the abrasive. In comparison, ISO 11127-7 uses a weight to volume ratio of abrasive to solvent (deionized water) to extract soluble salts from the abrasive. It is intended for use in the field as compared to ISO 11127-7, which is well suited for use in the laboratory.
Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen - Prüfverfahren für nichtmetallische Strahlmittel - Teil 8: Feldbestimmung von wasserlöslichen Chloriden (ISO 11127-8:2020)
Dieses Dokument legt ein Feldverfahren zur Bestimmung von wasserlöslichen Chloriden in nichtmetallischen Strahlmitteln fest. Dieses Feldverfahren wird als Kit mit allen Komponenten und einer vorher abgemessenen Extraktionslösung geliefert.
Dieses Dokument unterscheidet sich von ISO 11127 7 dadurch, dass gleiche Volumina der Strahlmittelprobe und der Extraktionslösung zur Bestimmung des Chloridgehalts im Strahlmittel verwendet werden. Demgegenüber wird in ISO 11127 7 ein Masse-zu-Volumen-Verhältnis von Strahlmittel zu Lösemittel (deionisiertes Wasser) verwendet, um lösliche Salze aus dem Strahlmittel zu extrahieren. Dieses Dokument ist für die Feldverwendung vorgesehen, während ISO 11127 7 eher für die Verwendung im Labor geeignet ist.

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.

Introduction
The use of non-metallic abrasive blast media is common practice for dry and wet surface cleaning and
blasting for substrate preparation prior to coating application. The non-metallic abrasive media are
taken from their natural environment which may contain various soluble salt contaminants including
chloride salts. High chloride salt concentrations in the abrasive blast media may provide for transfer
of the chloride ions to the substrate during the blasting process which would then cause premature
failure of the applied coating.
To limit the risk of contaminating the steel surface from contaminants in the abrasive media, the
chloride levels are quantified with ion specific testing methods that are reference
