1 Scope
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.
