(Main)Cathodic protection of steel in concrete (ISO 12696:2012)
Cathodic protection of steel in concrete (ISO 12696:2012)
ISO 12696:2011 specifies performance requirements for cathodic protection of steel in cement-based concrete, in both new and existing structures. It covers building and civil engineering structures, including normal reinforcement and prestressed reinforcement embedded in the concrete. It is applicable to uncoated steel reinforcement and to organic-coated steel reinforcement.
ISO 12696:2011 applies to steel embedded in atmospherically exposed, buried, immersed and tidal elements of buildings or structures.
Kathodischer Korrosionsschutz von Stahl in Beton (ISO 12696:2012)
Diese Internationale Norm legt die Leistungsanforderungen an den kathodischen Korrosionsschutz von Stahl
in Beton (auf Zementbasis) sowohl in neuen als auch bestehenden Bauwerken fest. Sie umfasst die der Luft
ausgesetzten Teile von Gebäuden und Tiefbauwerken, einschließlich in Beton eingebetteter nicht vorgespannter
und vorgespannter Bewehrung. Sie ist anwendbar auf unbeschichteten und auf organisch
beschichteten Bewehrungsstahl.
Diese Internationale Norm ist anwendbar auf Stahl, der in Teile von Gebäuden oder in Bauwerke eingebettet
ist, die der Luft ausgesetzt, erdverlegt oder unter Wasser befindlich oder durch Gezeiten beeinflusst sind.
ANMERKUNG 1 Anhang A gibt eine Übersicht über die Grundsätze des kathodischen Korrosionsschutzes und dessen
Anwendung auf Stahl in Beton.
ANMERKUNG 2 Diese Internationale Norm, die zwar nicht speziell für den kathodischen Schutz von Stahl in irgendeinem
Elektrolyten, ausgenommen Beton, vorgesehen ist, kann für den kathodischen Schutz von Stahl in anderen zementartigen
Materialien, wie sie beispielsweise bei in Stahlrahmen eingesetztem Mauerwerk, Bausteinen und mit Terracotta
verkleideten Bauwerken aus dem frühen 20. Jahrhundert zu finden sind, angewendet werden. Bei derartigen Anwendungen
sind zusätzliche Überlegungen für diese Bauwerke hinsichtlich Ausführung, Materialien und Einbau des kathodischen
Schutzes erforderlich; die Anforderungen der vorliegenden Internationalen Norm können jedoch für diese
Bauwerke angewendet werden.
Protection cathodique de l'acier dans le béton (ISO 12696:2012)
L'ISO 12696:2012 spécifie les exigences de performance pour la protection cathodique de l'acier dans le béton à base de ciment, pour les structures nouvelles comme pour les structures existantes. Elle traite des bâtiments et des ouvrages d'art, y compris les armatures et les précontraintes noyées dans le béton. Elle s'applique aux armatures en acier non revêtu et aux armatures en acier recouvert par un revêtement organique.
L'ISO 12696:2012 s'applique à l'acier noyé dans des éléments de bâtiments ou de structures qui sont exposés à l'atmosphère, enterrés, immergés ou soumis à la marée.
Katodna zaščita jekla v betonu (ISO 12696:2012)
Ta mednarodni standard določa zahteve glede zmogljivosti za katodno zaščito jekla v betonu na osnovi cementa v novih in obstoječih zgradbah. Zajema stavbe in gradbene inženirske zgradbe, vključno z običajno armaturo in prednapeto armaturo v betonu. Uporablja se za neprevlečeno jekleno armaturo in organsko prevlečeno jekleno armaturo. Ta mednarodni standard se uporablja za jeklo v ozračju izpostavljenih, zakopanih, potopljenih in plimnih elementih stavb ali zgradb.
