Metallpulver - Bestimmung des Sauerstoffgehaltes durch Reduktionsverfahren - Teil 3: Wasserstoffreduzierbarer Sauerstoff (ISO 4491-3:1997)

Dieser Teil der ISO 4491 legt ein Verfahren zur Bestimmung des wasserstoffreduzierbaren Anteils an Sauerstoff von Metallpulvern mit einem Sauerstoff-Massenanteil von 0,05 % bis 3 % fest.
Das Verfahren ist auf unlegierte, teilweise legierte oder vollständig legierte Metallpulver sowie aus Mischungen von Carbiden und Bindemetallen anwendbar. Es kann nicht angewendet werden auf Pulver mit Gleitmittelzusätzen oder organischen Bindemitteln.
Das Verfahren darf bei Einsatz einer speziellen katalytischen Vorrichtung auf kohlenstoffhaltige Pulver ausgedehnt werden.
Diese Norm ist im Zusammenhang mit ISO 760 und ISO 4491-1 anzuwenden.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
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. IS0
