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 the level of free moisture present in nonmetallic blast-cleaning abrasives. It is determined by measuring the mass lost on heating.
