Determination of boron(III) oxide in refractory products -- Part 2: Acid extraction method for the determination of boron(III) oxide in binder components
This standard was last reviewed and confirmed in 2014. Therefore this version remains current.
ISO 21078-2:2006 specifies procedures of chemical analysis for the determination of boron(III) oxide used as a binder component added to aluminosilicate refractories, using an acid extraction method.
It is applicable for refractories containing less than 1 % (mass fraction) of boron(III) oxide.
