This International Standard specifies a gravimetric method for the determination of the mass fraction of insoluble (free) carbon in carbides and hardmetals.
This method is applicable to
-
carbides of hafnium, molybdenum, niobium, tantalum, titanium, vanadium, tungsten and zirconium,
-
mixtures of these carbides and binder metals, free of lubricant, and
-
all grades of presintered or sintered hardmetals, produced from these carbides,
having a mass fraction of insoluble carbon between 0,02%and 0,5%.
