ISO 11127-7:2011 pdf download – Preparation of steel substrates beforeapplication of paints and related products – Test methods for non-metallic blast-cleaning abrasives —Part 7: Determination of water-soluble chlorides.
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 nonmetallic blast-cleaning abrasives. Information on all parts of both series is given In Annex A.
This part of ISO 11127 specifies a method for the determination of water-soluble cNondes in non-metallic blastcleaning abrasives.
