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 %.
