Corrosion of metals and alloys - Corrosivity of atmospheres - Determination of corrosion rate of standard specimens for the evaluation of corrosivity (ISO 9226:2012)

ISO 9226:2012 specifies methods which can be used for the determination of corrosion rate with standard specimens. The values obtained from the measurements (corrosion rates for the first year of exposure) are intended to be used as classification criteria for the evaluation of atmospheric corrosivity according to ISO 9223. They can also be used for informative evaluation of atmospheric corrosivity beyond the scope of ISO 9223.

Korrosion von Metallen und Legierungen - Korrosivität von Atmosphären - Bestimmung der Korrosionsgeschwindigkeit von Standardproben zur Ermittlung der Korrosivität (ISO 9226:2012)

Diese Internationale Norm legt Verfahren fest, die zur Bestimmung der Korrosionsgeschwindigkeit mit
Standardproben angewendet werden können. Die aus den Messungen erhaltenen Werte (Korrosionsgeschwindigkeiten
nach dem ersten Jahr der Auslagerung) sind dafür vorgesehen, als
Klassifizierungskriterien zur Ermittlung der atmosphärischen Korrosivität nach ISO 9223 verwendet zu
werden. Sie können außerdem zur informativen Ermittlung der atmosphärischen Korrosivität über den
Anwendungsbereich von ISO 9223 hinaus verwendet werden.

Corrosion des métaux et alliages - Corrosivité des atmosphères - Détermination de la vitesse de corrosion d'éprouvettes de référence pour l'évaluation de la corrosivité (ISO 9226:2012)

L'ISO 9226:2012 spécifie les méthodes utilisables pour déterminer la vitesse de corrosion d'éprouvettes de référence. Les valeurs obtenues par mesurage (vitesses de corrosion pour la première année d'exposition) sont destinées à servir de critères de classification pour l'évaluation de la corrosivité des atmosphères conformément à l'ISO 9223. Elles peuvent également servir pour l'évaluation informative de la corrosivité atmosphérique ne relevant pas du domaine d'application de l'ISO 9223.

Korozija kovin in zlitin - Korozivnost v atmosferskem okolju - Ugotavljanje hitrosti korozije s standardnimi vzorci za ocenjevanje korozivnosti (ISO 9226:2012)

Ta mednarodni standard določa metode, ki jih je mogoče uporabiti za ugotavljanje hitrosti korozije s standardnimi vzorci. Vrednosti, pridobljene z meritvami (hitrosti korozije za prvo leto izpostavljenosti) se uporabljajo kot merila za razvrščanje za ocenjevanje korozivnosti v atmosferskem okolju v skladu s standardom ISO 9223. Uporabljajo se lahko tudi za informativno ocenjevanje korozivnosti v atmosferskem okolju, ki presega področje uporabe standarda ISO 9223.

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. Pub
