CP Criteria Interactive Quiz

Use this CP criteria quiz to test whether you can choose and apply cathodic protection criteria without confusing ON, instant-off, and depolarized readings.

What This Quiz Covers

Criteria questions are where many CP learners make expensive mistakes. A potential value is incomplete without the reference electrode type, interruption context, and the criterion being applied. This quiz focuses on the logic behind −850 mVCSE, instant-off measurement, polarization change, and why the 100 mV criterion is not simply a fallback phrase.

Skills Tested

  • Separate ON, instant-off, polarized, and depolarized readings.
  • Calculate and interpret polarization shift where applicable.
  • Recognize why reference electrode type must be stated with a potential.
  • Avoid applying a criterion when the data do not support it.

How to Use This Quiz

Use this quiz after reading the criteria guides and before writing or reviewing CP survey findings. Missed questions often indicate a terminology problem that can lead directly to incorrect report language.

Each attempt randomly selects 10 questions from the topic question bank and shuffles the answer choices. Use the explanations after submission to identify the exact concepts that need review.

Common Questions

Why is a potential value incomplete by itself?

A potential must be tied to a reference electrode type and measurement condition. For example, a −850 mVCSE value must still be tied to the measurement condition, such as ON, instant-off, native, or depolarized.

Is the 100 mV polarization criterion just a fallback when −850 mVCSE fails?

No. The 100 mV criterion requires appropriate polarization or depolarization data. It should not be claimed unless the data support that conclusion.

What should I review if I miss criteria questions?

Review instant-off readings, polarized potentials, depolarized potentials, reference electrode types, and the difference between measured values and calculated polarization change.
