This document specifies a test method for the determination of the Vickers hardness of metallic blast-cleaning abrasives. This method is not recommended for the testing of particle sizes below 0,3 mm. NOTE: Accurate testing of particles below 0,3 mm (grades S040/G050) is extremely difficult. 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
