Use for Definitions
Glossary pages are short term explainers. Use the learning guides for deeper instruction and field interpretation.
Cathodic Protection Glossary
This glossary provides short technical definitions for cathodic protection, corrosion, field testing, electrical, troubleshooting, and reporting terms.
Use the glossary when you need a quick definition, then use the learning guides for deeper explanation and field interpretation.
1. Corrosion Cell Terms
These terms describe the basic electrochemical parts of a corrosion cell and are useful before studying how CP changes corrosion behavior.
2. Polarization and Criteria Terms
These terms appear frequently in CP criteria, instant-off testing, depolarization testing, and report conclusions.
3. Equipment and System Terms
These terms describe the field equipment and system features commonly encountered during CP surveys, inspections, and troubleshooting.
4. Troubleshooting Terms
These terms describe conditions that can make CP data harder to interpret or prevent protective current from reaching the intended structure surface.
How to Use the Glossary
Check Related Pages
Each glossary entry links to related learning, formula, standards, or application pages where the concept is used.
Avoid Isolated Interpretation
CP terms often depend on test condition, structure type, reference electrode, circuit behavior, and applicable criteria.

Glossary Terms Are Context-Dependent
Many CP terms cannot be interpreted correctly in isolation. A term such as instant-off, polarization, native potential, shielding, or interference depends on the structure being tested, the reference electrode used, the measurement condition, and the applicable criterion. Use the glossary for quick definitions, then follow the related learning pages when the term affects a field conclusion.
