ISO 12696:2016 混凝土中钢的阴极保护

标准编号：ISO 12696:2016

中文名称：混凝土中钢的阴极保护

英文名称：Cathodic protection of steel in concrete

发布日期：2016-12

标准范围

ISO 12696:2016规定了新结构和现有结构中水泥基混凝土中钢筋阴极保护的性能要求。它包括建筑和土木工程结构，包括嵌入混凝土中的普通钢筋和预应力钢筋。适用于无涂层钢筋和有机涂层钢筋。ISO 12696:2016适用于嵌入建筑物或结构的大气暴露、掩埋、浸没和潮汐元件中的钢。注1:附录A给出了阴极保护原理及其在混凝土中的应用指南。注2 ISO 12696:2016虽然不是专门针对除混凝土外的任何电解液中的钢材阴极保护，但也可应用于其他胶结材料中的钢材阴极保护，例如20世纪早期的钢框架砌体、砖和陶土覆盖建筑中的钢材阴极保护。在此类应用中，需要在阴极保护的设计、材料和安装方面对这些结构进行额外考虑；然而，本文件的要求可适用于这些系统。

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.
