What is the minimum negative polarized potential required with cathodic protection applied in respect to the Copper-Silver Electrode (CSE)?

• A. 750mV
• B. 850mV
• C. 950mV
• D. 1050mV

Answer: (B)

The minimum negative polarized potential required for effective cathodic protection when using the Copper-Silver Electrode (CSE) as a reference is typically recognized as 850mV. This value is established to ensure that the cathodic protection system is adequately protecting the metal surface by shifting its potential to a level where corrosion is significantly reduced. Copper-Silver Electrodes are commonly utilized in cathodic protection for various metal structures, and the 850mV benchmark signifies a level where the potential is negative enough to provide a protective barrier against corrosion. If the potential is more negative than this threshold, it ensures that the protection is effective and indicates that the steel or metal in question is adequately polarized to mitigate corrosive processes. Establishing the correct polarized potential is crucial for the longevity and integrity of structures exposed to corrosive environments, and adhering to the 850mV standard helps in achieving optimal protection performance.
