ISO 11127-4:2020 PDF

Scope: 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. 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.
