Hardmetals - Determination of total carbon - Gravimetric method (ISO 3907:2009)

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 %.

Hartmetalle - Bestimmung des Gesamtkohlenstoff-Gehaltes - Gravimetrisches Verfahren (ISO 3907:2009)

Diese Internationale Norm legt ein gravimetrisches Verfahren zur Bestimmung des Gesamtkohlenstoff-Gehaltes (Massenanteiles) von Carbiden und Hartmetallen fest.
Dieses Verfahren ist anwendbar bei
-   Chrom-, Hafnium-, Molybdän-, Niob-, Tantal-, Titan-, Vanadium-, Wolfram- und Zirkoncarbiden,
-   Gemischen aus diesen Carbiden und Bindemetallen, frei von Bindemitteln,
-   allen Arten vorgesinterter oder gesinterter Hartmetalle, die aus diesen Carbiden erzeugt wurden,
mit einem Gesamtkohlenstoff-Gehalt über 4 % (Massenanteil).

Métaux-durs - Dosage du carbone total - Méthode gravimétrique (ISO 3907:2009)

L'ISO 3907:2009 spécifie une méthode gravimétrique de dosage du carbone total (fraction massique de carbone total) dans les carbures et les métaux-durs.
Elle est applicable aux
carbures de chrome, 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 à partir de ces carbures,
dont la fraction massique de carbone total est supérieure à 4 %.

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 electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 3907 was prepared by Technical Committee ISO/TC 119, Powder metallurgy, Subcommittee SC 4,

Sampling and testing methods for hardmetal.

This third edition cancels and replaces the second edition (ISO 3907:1985), which has been technically

revised.
