(Main)Cathodic protection of steel in concrete (ISO 12696:2016)
Cathodic protection of steel in concrete (ISO 12696:2016)
ISO 12696:2016 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 12696:2016 applies to steel embedded in atmospherically exposed, buried, immersed and tidal elements of buildings or structures.
NOTE 1 Annex A gives guidance on the principles of cathodic protection and its application to steel in concrete.
NOTE 2 ISO 12696:2016, while not specifically intended to address cathodic protection of steel in any electrolyte except concrete, can be applied to cathodic protection of steel in other cementitious materials such as are found, for example, in early 20th century steel-framed masonry, brick and terracotta clad buildings. In such applications, additional considerations specific to these structures are required in respect of design, materials and installation of cathodic protection; however, the requirements of this document can be applied to these systems.
Kathodischer Korrosionsschutz von Stahl in Beton (ISO 12696:2016)
Protection cathodique de l'acier dans le béton (ISO 12696:2016)
ISO 12696:2016 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. Il traite des bâtiments et des ouvrages d'art, y compris les armatures et les précontraintes noyées dans le béton. Il s'applique aux armatures en acier non revêtu et aux armatures en acier recouvert par un revêtement organique.
ISO 12696:2016 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.
NOTE 1 L'Annexe A fournit des lignes directrices relatives aux principes de la protection cathodique et à son application à l'acier dans le béton.
NOTE 2 Bien qu'il ne soit pas spécifiquement destiné à traiter de la protection cathodique de l'acier dans n'importe quel autre électrolyte que le béton, le présent document peut s'appliquer à la protection cathodique de l'acier dans d'autres matériaux à base de ciment tels que ceux rencontrés, par exemple, dans les bâtiments à charpente d'acier du début du 20e siècle à parement de maçonnerie, de brique et de terre cuite. Dans de telles applications, des considérations supplémentaires spécifiques à ces structures sont à prendre en compte en ce qui concerne la conception, les matériaux et l'installation de la protection cathodique; cependant, les exigences du présent document peuvent être appliquées à ces systèmes.
Katodna zaščita jekla v betonu (ISO 12696:2016)
Ta dokument določa zahteve glede učinkovitosti za katodno zaščito jekla v betonu na osnovi cementa v novih in obstoječih objektih. Zajema stavbe in gradbene inženirske objekte, vključno z običajno armaturo in prednapeto armaturo v betonu. Uporablja se za neprevlečeno jekleno armaturo in organsko prevlečeno jekleno armaturo.
Ta dokument se uporablja za jeklo v atmosferi izpostavljenih, zakopanih, potopljenih in plimnih
elementih stavb ali objektov.
OPOMBA 1: Dodatek A podaja smernice o načelih katodne zaščite in njeni uporabi za jeklo v betonu.
OPOMBA 2: Ta dokument, čeprav ne obravnava posebej katodne zaščite jekla v katerem koli elektrolitu razen betona, se lahko uporablja za katodno zaščito jekla v drugih cementnih materialih, ki so lahko prisotni na primer v stavbah iz zgodnjega 20. stoletja, izdelanih iz zidakov z jeklenim ogrodjem, opek in terakote. Pri takih vrstah uporabe so potrebni dodatni premisleki, posebej namenjeni tem strukturam, v zvezi z načrtovanjem, materiali in namestitvijo katodne zaščite, vendar se lahko zahteve iz tega dokumenta uporabljajo za te sisteme.
