Sample Questions

Question 1
What is the standard -850 mV criterion for cathodic protection of buried steel as specified in NACE SP0169, and what reference electrode is it measured against?
-850 mV measured to a saturated Ag/AgCl reference electrode
-850 mV (polarized or with IR drop considered) measured to a saturated copper/copper sulfate (CSE) reference electrode
-850 mV measured to a standard hydrogen electrode (SHE)
-850 mV measured to a zinc reference electrode
Question 2
A CP tester measures a pipe-to-soil potential of -900 mV vs CSE with the rectifier ON. After instant-off, the potential reads -780 mV vs CSE. Which of the following statements is MOST accurate?
The structure meets the -850 mV polarized criterion
The IR drop is 120 mV and the instant-off potential does not meet the -850 mV polarized criterion
The structure is overprotected
The CSE reference is contaminated
Question 3
Which of the following is the PRIMARY purpose of the instant-off (interrupt) technique when measuring pipe-to-soil potential?
To reduce meter battery consumption
To eliminate the IR drop component from the measurement so the polarized potential can be read
To measure AC voltage separately from DC
To verify rectifier efficiency
Question 4
A CP tester reads a pipe-to-soil potential of -0.780 V using a silver/silver chloride (Ag/AgCl, saturated KCl) reference electrode. Approximately what is the equivalent potential in mV vs CSE?
-661 mV
-780 mV
-899 mV
-960 mV
Question 5
What is the MOST common electrolyte used in a portable copper/copper sulfate reference electrode?
Distilled water
A saturated copper sulfate (CuSO4) solution with excess solid crystals
Sodium chloride solution
Potassium chloride gel
