This document specifies the reference method used for type testing and in cases of dispute, for the
determination of the methylene blue value of the size 0/2 mm fraction in fine aggregates or all-in
aggregates (MB). It also specifies the reference method for the determination of the methylene blue
value of the size 0/0,125 mm fraction (MBF) in normative Annex A. Other methods can be used for other
purposes, such as factory production control, provided that an appropriate working relationship with
the suitable reference method has been established.
Annex B specifies the preparation of 10 g/l methylene blue solution and Annex C specifies the
procedure for the determination of the methylene blue value of kaolinite (MBk). Annexes B and C are
normative.
A conformity check, adding a single quantity of dye solution equivalent to a specified limiting value and
which can be used as part of a production control process, is described in informative Annex D.
An example of a test data sheet is given in informative Annex E.
