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 %.

This European Standard was approved by CEN on 29 September 2009.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the CEN Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as the
official versions.

ISO 3907:2009(E)
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.
