(Main)Corrosion of metals and alloys - Aqueous corrosion testing of zirconium alloys for use in nuclear power reactors (ISO 10270:2022)
Corrosion of metals and alloys - Aqueous corrosion testing of zirconium alloys for use in nuclear power reactors (ISO 10270:2022)
This document specifies:
a) the determination of mass gain;
b) the surface inspection of products of zirconium and its alloys when corrosion is tested in water at 360 °C or in steam at or above 400 °C;
c) the performance of tests in steam at 10,3 MPa.
This document is applicable to wrought products, castings, powder metallurgy products and weld metals.
This method has been widely used in the development of new alloys, heat-treating practices and for the evaluation of welding techniques. It is applicable for use in its entirety to the extent specified for a product acceptance test, rather than merely a means of assessing performance in service.
Korrosion von Metallen und Legierungen - Korrosionsprüfung in wässrigen Lösungen für in Kernreaktoren angewendete Zirkoniumlegierungen (ISO 10270:2022)
Dieses Dokument legt fest:
a) die Bestimmung der Massezunahme;
b) die Untersuchung der Oberflächen von Produkten aus Zirkonium und Zirkoniumlegierungen nach einer Korrosionsprüfung in Wasser bei 360 °C oder in Dampf bei oder über 400 °C;
c) die Durchführung der Prüfungen in Dampf unter einem Druck von 10,3 MPa.
Dieses Dokument ist auf Schmiedeprodukte, Gussteile, pulvermetallurgische Produkte und Schweißgut anwendbar.
Das Verfahren wurde bereits vielfach zur Entwicklung neuer Legierungen und Wärmebehandlungsverfahren sowie zur Bewertung von Schweißverfahren genutzt. Es ist nicht nur zur Beurteilung des Betriebsverhaltens anwendbar, sondern stattdessen als Ganzes in dem Umfang, der zur Abnahmeprüfung des jeweiligen Produkts festgelegt ist.
WARNUNG - Dieses Dokuments kann die Anwendung von gefährlichen Materialien, Arbeitsgängen und Einrichtungen zur Folge haben (siehe Abschnitt 9). Die Anwender dieses Dokuments sind dafür verantwortlich, vor Anwendung geeignete Maßnahmen zur Einhaltung der Sicherheit und zum Schutz der Gesundheit zu ergreifen und die zutreffenden gesetzlichen Einschränkungen zu beachten.
Corrosion des métaux et alliages - Essais de corrosion aqueuse des alliages de zirconium utilisés dans les réacteurs nucléaires (ISO 10270:2022)
Le présent document décrit :
a) la détermination du gain en masse ;
b) le contrôle superficiel des produits en zirconium et en alliages de zirconium après essai de corrosion dans l'eau à 360 °C et dans la vapeur à 400 °C ou plus ;
c) les performances des essais dans la vapeur à 10,3 MPa.
Le présent document est applicable aux produits corroyés, moulés, aux produits de la métallurgie des poudres et aux métaux d'apport pour le soudage.
La méthode a été beaucoup utilisée pour mettre au point de nouveaux alliages et de nouvelles techniques de traitement thermique et à évaluer les techniques de soudage Elle peut être utilisée dans sa totalité comme moyen de réception des produits plutôt que comme moyen d'évaluation de leurs propriétés en service.
Korozija kovin in zlitin - Preskušanje vodne korozije cirkonijevih zlitin za uporabo v jedrskih reaktorjih (ISO 10270:2022)
Ta dokument določa: a) določevanje povečanja mase; b) pregledovanje površine proizvodov iz cirkonija in njegovih zlitin pri preskušanju korozije v vodi pri temperaturi 360 °C ali v pari pri temperaturi 400 °C ali več; c) izvajanje preskusov v pari pri tlaku 10,3 MPa. Ta dokument se uporablja za gnetene zlitine, ulitke, proizvode, izdelane z metalurgijo prahu, in zvarne kovine. Ta metoda se pogosto uporablja pri razvoju novih zlitin, v postopkih toplotne obdelave in za vrednotenje tehnik varjenja. V obsegu, določenem za preskus sprejemljivosti proizvoda, se lahko uporablja v celoti in ne zgolj kot sredstvo za ocenjevanje učinkovitosti delovanja.
