AMPP SP21520-2023, Acceptance Criteria for Cathodic Protection of Steel in Concrete Structures

Historically, NACE SP0290, NACE SP0216, and NACE SP0408 included sets of criteria that needed to be satisfied to indicate that a cathodic protection (CP) system is delivering adequate current to passivate the reinforcing steel or reduce its corrosion current to low and non-destructive levels. These criteria were mostly the same, so the aim of this standard is to set out the essential criteria that each one of the above standards must satisfy in a single document. This allows each of the above standards, which deal with different applications of cathodic protection, to concentrate and expand on aspects that are specific for each application. This standard further suggests techniques that can be employed to estimate the level of protection achieved by a non-compliant cathodic protection method.

NACE SP0112-2023, Corrosion Management System for Atmospherically Exposed Reinforced Concrete Structures

Product Number: NACE SP0112-2023
Publication Date: 2023

This AMPP standard practice provides a structure for setting up and maintaining a Corrosion Management System (the System) for existing atmospherically exposed reinforced concrete structures.  This standard is concerned with the risk-based management of corrosion to maintain the safe operation of structures and to minimize the risk of unexpected failures and unplanned closures and outages.  The Standard applies to any reinforced concrete structure that is atmospherically exposed including: parking structures, bridges, residential or commercial buildings, and any structures at risk of corrosion development.
