31、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
32、. 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 chlorides in non-metallic blast-cleaning abrasives.2 Normative referencesThe following referenced documents are indispensable for the application of this doc

37、 and add (100 1) ml of water. Shake for 5 min and allow to stand for 1 h. Then shake again for 5 min and allow to settle. If the solution does not completely clear, filter it by any suitable method.6.3 Take 25 ml of the solution. Add 0,1 ml of sulfuric acid (3.1) and dilute to approximately 75 ml wi
