1 Scope
This International Standard specifies a gravimetric method for the determination of
the mass fraction of total carbon in carbides and hardmetals.
This method is applicable to
-
— carbides of chromium, hafnium, molybdenum, niobium, tantalum, titanium, vanadium,
tungsten and zirconium,
-
— mixtures of these carbides and binder metals, free of lubricant,
-
— all grade of presintered or sintered hardmetals, produced from these carbides, and
having a mass fraction of total carbon exceeding 4 %.
