This document specifies a test method for the determination of foreign matter in metallic blast-cleaning 
abrasives.
The purpose of the test is to establish the level to which the abrasive is contaminated by foreign matter. 
The level of foreign matter, e.g. oxides and residual metallurgical slag, is determined by magnetic 
separation.
This is one of a number of parts of ISO 11125 dealing with the sampling and testing of metallic abrasives 
for blast-cleaning.
The types of metallic abrasive and requirements on each are contained in the various parts of ISO 11124.
The ISO 11124 and ISO 11125 series have been drafted as a coherent set of International Standards on 
metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.nd edition 2018-08 Preparation of steel substrates before application of paints and related products — Test methods for metallic blast-cleaning abrasives — Part 6: Determination of foreign matter Préparation des subjectiles d'acier avant application de peintures et de produits assimilés — Méthodes d'essai pour abrasifs métalliques destinés à la préparation par projection — Partie 6: Détermination des particules étrangères Reference number ISO 11125-6:2018(E)
