Hardmetals - Determination of insoluble (free) carbon - Gravimetric method (ISO 3908:2009)

This International Standard specifies a gravimetric method for the determination of the mass fraction of insoluble (free) carbon in carbides and hardmetals. This method is applicable to - carbides of hafnium, molybdenum, niobium, tantalum, titanium, vanadium, tungsten and zirconium, - mixtures of these carbides and binder metals, free of lubricant, and - all grades of presintered or sintered hardmetals, produced from these carbides, having a mass fraction of insoluble carbon between 0,02 % and 0,5 %.

Hartmetalle - Bestimmung des unlöslichen (freien) Kohlnestoffgehaltes - Gravimetrisches Verfahren (ISO 3908:2009)

Diese Internationale Norm legt ein gravimetrisches Verfahren zur Bestimmung des unlöslichen (freien) Kohlenstoffgehaltes von Carbiden und Hartmetallen fest.

Métaux-durs - Dosage du carbone insoluble (libre) - Méthode gravimétrique (ISO 3908:2009)

L'ISO 3908:2009 spécifie une méthode gravimétrique de dosage du carbone insoluble (libre) [fraction massique de carbone insoluble (libre)] dans les carbures et les métaux-durs.
Elle est applicable aux
― carbures de hafnium, molybdène, niobium, tantale, titane, vanadium, tungstène et zirconium,
― mélanges de ces carbures et de métaux liants non lubrifiés,
― métaux-durs de toutes nuances, préfrittés ou frittés, produits de ces carbures,
dont la fraction massique de carbone insoluble est comprise entre 0,02 % et 0,5 %.

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
