ÖNORM EN ISO 11125-3

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. This patt of ISO 11125 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 1 Accurate testing of particles below 0,3 mm (grades S040/G050) is extremely difficult. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 11125. At the time of publication, the editions indicated were valid. All Standards are subject to revision, and Parties to agreements based on this part of ISO 11125 are encouraged to investigate the possibility of applying the most recent editions of the Standards indicated below.
