Hardmetals — Determination of total carbon — Gravimetric method

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

having a mass fraction of total carbon exceeding 4 %.
