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.

Dieser Teil der Norm legt ein Prüfverfahren zur Bestimmung der Vickershärte von metallischen Strahlmitteln fest. Dieses Verfahren wird nicht für Korngrößen unter 0,3 mm empfohlen. Die verschiedenen Arten metallischer Strahlmittel und Anforderungen an diese sind in den verschiedenen Teilen von ISO 11124 enthalten. Die Normenreihen ISO 11124 und ISO 11125 wurden als zusammengehöriger Satz von Internationalen Normen über metallische Strahlmittel ausgearbeitet.
