Chapter Five

Anode Testing and Quality Control

Abstract

Anodes play a key role in cathodic protection. An anode’s current output depends on its chemical composition, length, cross-section area, and electrical characteristics. The mass of the anode is also an important factor, and the production of the anode through defect-free casting helps to ensure that the anode is a high-quality product. Thus, this chapter discusses quality control for anode manufacturing and testing. Anode performance tests are introduced with guidance on what specification to use for acceptable testing methods. The sampling of test specimens is also an important part of the quality control process, and recommended practices are laid out in the guidelines and specifications ...
