Method of measurement of hydrogen permeation and determination of hydrogen uptake and transport in metals by an electrochemical technique (ISO 17081:2014)

ISO 17081:2014 specifies a laboratory method for the measurement of hydrogen
permeation and for the determination of hydrogen atom uptake and transport in
metals, using an electrochemical technique. The term "metal" as used in ISO
17081:2014 includes alloys.
ISO 17081:2014 describes a method for evaluating hydrogen uptake in metals,
based on measurement of steady-state hydrogen flux. It also describes a method
for determining effective diffusivity of hydrogen atoms in a metal and for
distinguishing reversible and irreversible trapping.
ISO 17081:2014 gives requirements for the preparation of specimens, control
and monitoring of the environmental variables, test procedures and analysis of
results.
ISO 17081:2014 may be applied, in principle, to all metals for which hydrogen
permeation is measurable and the method can be used to rank the relative
aggressivity of different environments in terms of the hydrogen uptake of the
exposed metal.

Elektrochemisches Verfahren zur Messung der Wasserstoffpermeation und zur Bestimmung von Wasserstoffaufnahme und -transport in Metallen (ISO 17081:2014)

1.1   In dieser Internationalen Norm wird ein elektrochemisches Laboratoriumsverfahren zur Messung der Wasserstoffpermeation und zur Bestimmung der Aufnahme und des Transports von Wasserstoffatomen in Metallen festgelegt. In dieser Internationalen Norm werden mit der Benennung „Metall“ auch Legierungen erfasst.
1.2   Diese Internationale Norm beschreibt ein Verfahren zur Bewertung der Wasserstoffaufnahme in Metallen, das auf der Messung der Wasserstoffströmung (des Wasserstoffflusses) im stationären Zustand beruht. Ferner werden Verfahren zur Bestimmung des effektiven Diffusionsvermögens von Wasserstoffatomen in einem Metall und zur Unterscheidung reversibler und irreversibler Fehlstellen beschrieben.
1.3   In dieser Internationalen Norm werden Anforderungen an die Vorbereitung der Proben, die Kontrolle und Überwachung der Umgebungsvariablen, die Prüfverfahren und die Auswertung der Ergebnisse festgelegt.
1.4   Diese Internationale Norm darf prinzipiell auf alle Metalle, bei denen Wasserstoffpermeation messbar ist, angewendet werden, und das Verfahren kann zur Klassifizierung der relativen Aggressivität unterschiedlicher Umgebungen in Bezug auf die Wasserstoffaufnahme des beanspruchten Metalls angewendet werden.

Méthode de mesure de la perméation de l'hydrogène et détermination de l'absorption d'hydrogène et de son transport dans les métaux à l'aide d'une technique électrochimique (ISO 17081:2014)

L'ISO 17081:2014 spécifie une méthode de laboratoire pour le mesurage de la perméation de l'hydrogène et la détermination de l'absorption et du transport des atomes d'hydrogène dans les métaux à l'aide d'une technique électrochimique. Le terme «métal» utilisé dans la présente Norme internationale comprend les alliages.
L'ISO 17081:2014 décrit une méthode permettant d'évaluer l'absorption d'hydrogène dans les métaux sur la base du mesurage d'un flux stationnaire d'hydrogène. Elle décrit également une méthode permettant de déterminer le coefficient de diffusion effective des atomes d'hydrogène dans un métal et de faire une distinction entre le piégeage réversible et le piégeage irréversible.
L'ISO 17081:2014 fournit des exigences concernant la préparation des éprouvettes, le contrôle et le suivi des variables environnementales, les modes opératoires d'essai et l'analyse des résultats.
L'ISO 17081:2014 peut s'appliquer, en principe, à tous les métaux pour lesquels la perméation de l'hydrogène est mesurable et la méthode peut être utilisée pour classer l'agressivité relative de différents environnements en termes d'absorption d'hydrogène par le métal exposé.

Metoda merjenja prodiranja vodika ter določanje njegovega vpijanja in prenosa v kovinah z elektrokemijsko tehniko (ISO 17081:2014)

Standard EN ISO 17081 določa laboratorijsko metodo merjenja prodiranja vodika ter določanje njegovega vpijanja in prenosa v kovinah z elektrokemijsko tehniko. Pojem »kovina« v tem mednarodnem standardu zajema tudi zlitine. Ta mednarodni standard opisuje metodo za ocenjevanje vpijanja vodika v kovinah, ki temelji na merjenju ustaljene hitrosti pretoka vodika. Prav tako opisuje metodo za določanje učinkovite razprševalnosti vodikovih atomov v kovinah in za razlikovanje med obrnljivim in dokončnim lovljenjem. Ta mednarodni standard določa zahteve za pripravo vzorcev, nadzor in spremljanje okoljskih spremenljivk, preskusnih postopkov in analizo rezultatov. Ta mednarodni standard se lahko načeloma uporablja za vse kovine, pri katerih je mogoče izmeriti prodiranje vodika, metoda pa se lahko uporablja za razvrščanje relativne agresivnosti različnih okolij glede na vpijanje vodika v izpostavljeni kovini.
