Objectives

The exams cover the following skill and knowledge factors:

• Basics of electricity, electrical laws, electrochemistry, corrosion and CP theory
• Polarity related to current flow and metal corrosion activity
• Conduct tests to identify shorts and continuity tests in CP systems
• Use test instruments to perform a variety of field tests such as structure-to-soil potentials, voltage and current measurements, soil resistivity, pipe/cable locating and rectifier readings
• CP components including impressed current systems, galvanic anodes and test stations
• Read shunts and understand their use in rectifiers, bonds, and anodes
• Perform periodic surveys to confirm the effectiveness of a CP system
• Reference cells, their maintenance, use, and precautions
• Basic location mapping, report preparation, and recordkeeping
• Review safety issues specific to CP
• Code requirements related to CP
