Product Details

Specifies a test method for the determination of the Vickers hardness (using a test force of 9,807 N, i.e. HV 1, when testing particles with a diameter greater than 0,5 mm, and a test force of 4,904 N, i.e. HV 0,5, when testing particles with a diameter of 0,3 mm to 0,5 mm). The method is not recommended for the testing of particle sizes below 0,3 mm. The purpose is to establish the soundness of the metallic abrasive. Significant levels of internal shrinkage or hollow particles will reduce the apparent density. Annex A gives information on the international standards series for metallic blast-cleaning abrasives ISO 11124 and ISO 11125.
