NF EN ISO 11125-3

Dans le cadre de la préparation des subjectiles d'acier avant travaux de peintures, le présent document donne une méthode de détermination de la dureté Vickers des abrasifs métalliques pour le nettoyage et la préparation des surfaces.

<p>This document specifies a test method for the determination of the Vickers hardness of metallic blast-cleaning abrasives.</p> <p>This method is not recommended for the testing of particle sizes below 0,3 mm.</p> <p>NOTE Accurate testing of particles below 0,3 mm (grades S040/G050) is extremely difficult.</p> <p>This is one of a number of parts of ISO 11125 dealing with the sampling and testing of metallic abrasives for blast-cleaning.</p> <p>The types of metallic abrasive and requirements on each are contained in the various parts of ISO 11124.</p> <p>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.</p>
