Abstract / scope
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 %.
