NF EN ISO 11125-3

Preparation of steel substrates before application of paints and related products - Test methods for metallic blast-cleaning abrasives - Part 3 : determination of hardness

This document 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 Accurate testing of particles below 0,3 mm (grades S040/G050) is extremely difficult.

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.
