Scope
This standard specifies the method for determining the amount of free silica dioxide (fSiO2) in limestone.
This standard is applicable to the determination of the amount of free silica dioxide in limestone, and can also be used for the determination of the amount of free silica dioxide in the raw materials of ordinary silicate cement.
Measurement range: a free silica dioxide amount of 1.00% to 10.00% (by mass fraction).
