Sintered metal materials, excluding hardmetals - Preparation of samples for chemical analysis for determination of carbon content (ISO 7625:2012)

ISO 7265:2012 specifies methods for preparing a sample from one or more sintered parts to be analysed for free or total carbon content. Combined carbon is determined as the difference between total and free carbon. This standard covers the preparation of samples for the determination of carbon by a chemical method, i.e. combustion in oxygen and measurement of the carbon dioxide produced, in accordance with ISO 437. It does not cover the preparation of samples for carbon determination by physical methods, such as metallography or spectroscopy.

Sintermetalle, ausgenommen Hartmetalle - Vorbereitung von Proben für die chemische Analyse zur Bestimmung des Kohlenstoffgehaltes (ISO 7625:2012)

Diese Internationale Norm legt Verfahren für die Vorbereitung einer Probe aus einem oder mehreren Sinterteilen aus Materialien fest, die auf den ungebundenen oder gesamten Kohlenstoffgehalt zu analysieren sind. Gebundener Kohlenstoff wird als Differenz zwischen dem gesamten und dem ungebundenen Kohlenstoff bestimmt. Diese Norm enthält die Vorbereitung von Proben für die Bestimmung des Kohlenstoffes durch ein chemisches Verfahren, d. h. Verbrennung in Sauerstoff und Messung des auftretenden Kohlendioxids nach ISO 437. Sie enthält nicht die Vorbereitung von Proben für die Bestimmung des Kohlenstoffes durch physikalische Verfahren, wie z. B. Metallographie oder Spektroskopie.

Matériaux métalliques frittés, à l'exclusion des métaux-durs - Préparation des échantillons pour analyse chimique en vue du dosage du carbone (ISO 7625:2012)

L'ISO 7625:2012 spécifie une méthode de préparation d'un échantillon à partir d'un ou de plusieurs fragments frittés de matériaux à analyser en vue de la détermination de leur teneur en carbone libre ou total. Le carbone combiné est déterminé par différence entre la teneur en carbone total et celle en carbone libre. L'ISO 7625:2012 concerne la préparation des échantillons pour le dosage du carbone au moyen d'une méthode chimique, à savoir par combustion dans l'oxygène et mesurage de la quantité de dioxyde de carbone formé, conformément à l'ISO 437. Elle ne concerne pas la préparation d'échantillons en vue du dosage du carbone par des méthodes physiques, telles que la métallographie ou la spectroscopie.

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.
