,Q1. A coating inspector observes flash rusting on a near-white blast-cleaned steel
surface within 30 minutes of abrasive blasting. Which combination of factors most
likely contributed, and what immediate action should be taken?
A. High humidity and soluble salts on the surface; re-blast and apply a temporary
protective coating.
B. Low ambient temperature and high air pressure; wait for surface to warm and
re-inspect.
C. Contaminated abrasive and excessive nozzle distance; replace abrasive and reduce
standoff.
D. Insufficient surface profile and high dew point; increase blast pressure and re-clean.
Correct Answer: A. High humidity and soluble salts on the surface; re-blast and
apply a temporary protective coating.
Rationale: Flash rusting occurs when moisture condenses on a reactive clean steel
surface, often due to high humidity and hygroscopic soluble salts. The correct response is
to re-blast to remove rust and salts, then apply a temporary protective coating if
immediate coating is not possible. Other options misidentify the cause or suggest
ineffective measures.
Why Wrong:
B - Low temperature alone does not cause flash rust; the presence of moisture and
salts is required.
C - Contaminated abrasive causes surface contamination, but flash rusting is primarily
a moisture-driven phenomenon.
D - Insufficient profile affects coating adhesion, not the rapid formation of flash rust.
Reference: NACE CIP Level 1 Manual, Chapter 3: Surface Preparation
Q2. During a coating inspection, you measure a 600 µm dry film thickness (DFT) on a
structural steel member that requires a 400-500 µm coating system. The spec allows a
maximum of 80% of readings below the minimum, but no reading may be below 90%
of the specified minimum. What is your disposition?
A. Accept, because the average is within the specified range.
B. Reject, because the reading exceeds the maximum allowable DFT.
C. Accept, if the thickness is uniform across the member.
D. Reject, because the reading is below the minimum DFT requirement.
Correct Answer: B. Reject, because the reading exceeds the maximum allowable DFT.
Rationale: The measured DFT of 600 µm exceeds the maximum specified thickness of 500
µm. Excessive DFT can lead to solvent entrapment, poor adhesion, and cracking.
Therefore, the coating must be rejected regardless of average or uniformity. The other
options ignore the maximum limit.
Page 3
, Why Wrong:
A - Average thickness does not justify exceeding the maximum limit.
C - Uniformity does not mitigate the risk of excessive thickness.
D - The reading is above, not below, the minimum.
Reference: ISO 19840 / SSPC-PA 2, Coating Thickness Measurement
Q3. A coating inspector is evaluating a zinc-rich primer on a steel bridge. The
specification requires a DFT of 75-100 µm. Using a Type 2 DFT gauge, you obtain an
average of 85 µm, but the substrate temperature is 5°C and the coating is not fully
cured. Which factor most likely affects the accuracy of your measurement?
A. The gauge is not calibrated for zinc-rich coatings.
B. The low substrate temperature slows curing, affecting the gauge's magnetic
properties.
C. The surface roughness is too high, causing inaccurate readings.
D. The coating is too thin, leading to measurement errors.
Correct Answer: B. The low substrate temperature slows curing, affecting the gauge's
magnetic properties.
Rationale: Type 2 DFT gauges rely on magnetic induction or eddy current principles. The
curing of the coating, especially at low temperatures, can affect the magnetic properties of
the substrate-coating system, leading to inaccurate readings. Calibration, surface
roughness, and thickness are less likely to cause significant errors in this scenario.
Why Wrong:
A - Type 2 gauges are generally suitable for zinc-rich coatings if calibrated correctly.
C - Surface roughness affects measurement but is not directly related to curing
temperature.
D - The coating is within the specified range, so thickness is not the issue.
Reference: ASTM D7091, Standard Practice for Nondestructive Measurement of Dry Film
Thickness
Q4. A coating system is specified as 'ISO 12944-5 C5-M (High Durability)'. Which of
the following environments does this designation apply to, and what is the expected
service life?
A. Coastal marine atmosphere with high salinity; 15+ years to first major maintenance.
B. Industrial inland atmosphere with moderate pollution; 10-15 years to first major
maintenance.
C. Chemical immersion service; 5-10 years to first major maintenance.
D. Submerged freshwater service; 20+ years to first major maintenance.
Correct Answer: A. Coastal marine atmosphere with high salinity; 15+ years to first
major maintenance.
