Learning Outcomes

Learning Outcomes:

• Define activation, concentration, and resistance polarization, and the mathematical expressions of these concepts
• Recall the factors that affect polarization (area, temperature, relative movement, ion concentration, oxygen concentration)
• Identify errors in data collection/CP measurements including contact resistance errors, voltage drop errors, and reference electrode errors where the technologist is employed
• Determine ideal current distribution for a CP system based on different the affecting factors
• Apply advanced cathodic protection testing using correct measurement techniques to monitor CP system performance, accurately interpret the data collected to ensure optimum CP system performance
• Determine corrective action to the CP system if necessary
• Conduct and document interference tests to determine if DC or AC interference exists, identify the source and implement a method of control to mitigate the effects of stray current
• Design and install simplistic forms of galvanic and impressed current cathodic protection facilities and perform the necessary mathematical calculations
• Course completion:

Successful completion of the course is required to earn a certificate of course completion. Requirements are specific to each course and may include a combination of attendance, daily assessments, activities, quizzes, or knowledge checks.

Course Prerequisites:

A strong algebra and geometry background, with thorough understanding of unit conversions and scientific notation, is required as a minimum mathematics prerequisite. A knowledge and understanding of the following material is needed for this course:

• Electricity: DC electrical laws, series and parallel circuits, and rectifier circuits
• Electrochemistry: theory including electrochemical and galvanic series, polarization, Faraday's Law;
• Corrosion theory including polarization under different conditions;
• Cathodic protection: fundamentals, criteria, sacrificial and impressed current equipment including diodes, and different types of power supplies and anodes;
• Stray current interference;
• Testing equipment including voltmeters, ammeters, shunts (and calculations), ohmmeters, reference electrodes (and conversions), CP coupons, isolation and soil resistivity equipment.
• Field tests such as interrupted structure-to-electrolyte potentials, close interval potential surveys, isolation tests, road casing isolation tests, layer soil resistivity, troubleshooting and coating tests

Certification Exams:

• Certification requirements include case-based and theory exams delivered via computer-based testing (CBT). The multiple-choice CBT exam is scheduled separately from the course and delivered via Pearson VUE. The initial CBT exam is included with the course registration. Any Exam retake will incur additional cost to the applicant.
• To take the exam-only option, access My Certification Portal and select Schedule/Manage Exams to add both exams to your cart and purchase. Get more details in the Scheduling Your Pearson VUE Exam document.

 Renewal requirements:

• An approved recertification application is required every 3 years. The work experience requirement for renewals for all certifications is one and half (1.5) years for the most recent three (3) year period.
• As you prepare for renewal, please visit My Certification Portal to log and manage your work experience and Professional Development Hours (PDH's) needed. Your work experience and PDH's will be submitted as part of your renewal application but you can input PDH's at any time. See the certification renewal guide for PDH's requirements, our sample training PDH guide, and our PDH how-to videos. Certification holders are required to pay a non-refundable processing fee for renewal.
