This document specifies a method of assessing of whether a non-metallic blast-cleaning abrasive has a minimum hardness of 6 on Mohs' scale.
This document is a part of the ISO 11127 series dealing with the sampling and testing of non-metallic abrasives for blast-cleaning.
The types of non-metallic abrasive and requirements on each are contained in the ISO 11126 series.
The ISO 11126 and ISO 11127 series have been drafted as a coherent set of International Standards on non-metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.
NOTE    The test described in this document is a pass/fail test and is not a method for the accurate determination of hardness.
