本标准实施规程旨在介绍CP的应用规程，以控制与电解液接触的等级储罐底部碳钢的外部腐蚀。包括原阳极阴极保护系统和外加电流阴极保护系统的应用实践。包括现有储罐升级和新建储罐的设计标准。本标准由任务组013维护。

The purpose of this standard practice is to present practices for application of CP to control external corrosion of carbon steel on-grade storage tank bottoms that are in contact with an electrolyte. Practices for application of both galvanic anode CP systems and impressed current CP systems are included. Design criteria for the upgrade of existing tanks as well as for newly constructed tanks are included. This standard is maintained by Task Group 013.
