Tests for geometrical properties of aggregates - Part 9: Assessment of fines - Methylene blue test
This standard describes the reference method used for type testing and in cases of dispute for the determination of the methylene blue value of the 0/ 2 mm fraction in fine aggregates or all-in aggregates (MB). It also describes the reference method for the determination of the methylene blue value of the 0/ 0,125 mm fraction (MBF) in Annex A. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the suitable reference method has been established.
