BS EN ISO 3907:2009

This standard BS EN ISO 3907:2009 Hardmetals. Determination of total carbon. Gravimetric method is classified in these ICS categories:

• 77.160 Powder metallurgy

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 %.
