Hardmetals. Determination of total carbon. Gravimetric method. | Status: Current, Under review

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 %.
