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

ISO 3908:2009 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) Kohlenstoff-Gehaltes - Gravimetrisches Verfahren (ISO 3908:2009)

Diese Internationale Norm legt ein gravimetrisches Verfahren zur Bestimmung des unlöslichen (freien) Kohlenstoffgehaltes (Massenanteiles) von Carbiden und Hartmetallen fest.
Dieses Verfahren ist anwendbar bei
-   Hafnium-, Molybdän-, Niob-, Tantal-, Titan-, Vanadium-, Wolfram- und Zirkoncarbiden,
-   Gemischen aus diesen Carbiden und Bindemetallen, frei von Bindemitteln, und
-   allen Arten vorgesinterter oder gesinterter Hartmetalle, die aus diesen Carbiden erzeugt wurden,
mit einem Gehalt an unlöslichem Kohlenstoff zwischen 0,02 % (Massenanteil) und 0,5 % (Massenanteil).

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 %.

Foreword

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

International Electrotechnical Commission (IEC) on all matters of ele
