ISO 3907:2009 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
