BS EN ISO 11127-4:2011

Preparation of steel substrates before application of paints and related products. Test methods for non-metallic blast-cleaning abrasives. Assessment of hardness by a glass slide test | Status: Superseded, Withdrawn

1 Scope This is one of a number of parts of ISO 11127 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 ISO 11126. 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. This part of ISO 11127 specifies a method of assessing whether a non-metallic blast-cleaning abrasive has a minimum hardness of 6 on Mohs' scale.

NOTE The test described in this part of ISO 11127 is a pass/fail test and is not a method for the accurate determination of hardness.
