Introduction
This structured NACE CIP Level 1 Exam format for 2026/2027 provides the complete layout for
generating high-quality actual questions with verified answers. All questions are formatted in bold,
with correct answers explicitly highlighted in Green and rationales. It emphasizes coating inspection
compliance, surface preparation standards, instrument calibration, and safety protocols critical to
professional application, ensuring absolutely no repetition of questions throughout the entire set and
zero disclaimers.
Question 1: Corrosion will generally NOT occur on a steel substrate when:
A. It is cool
B. There is no moisture
C. The steel is completely immersed
D. The temperature is 72° or above
Correct Answer: There is no moisture
Rationale: Corrosion requires an electrolyte (moisture) to complete the electrochemical circuit.
Without moisture, the flow of ions is prevented.
Question 2: New steel is not homogenous and contains which of the following elements
of a corrosion cell?
A. Anodes, cathodes, and electrolyte
B. Electrolyte, conductors, and anodes
C. Anodes, cathodes, and a metallic conductor
D. Anodes, cathodes, metallic conductor, and electrolytes
Correct Answer: Anodes, cathodes, and a metallic conductor
Rationale: Steel naturally contains areas of different potential that act as anodes and cathodes, with
the metal itself acting as the conductor.
Question 3: Which of the following is anodic with respect to carbon steel when in a
seawater electrolyte?
A. Magnesium
B. Copper
C. Stainless steel
D. Titanium
Correct Answer: Magnesium
Rationale: On the galvanic series in seawater, magnesium is more active (anodic) than carbon steel,
meaning it will sacrifice itself to protect the steel.
Question 4: Chemical salts dissolved in an electrolyte generally contribute to corrosion
by:
A. Acting as anodes
B. Acting as cathodes
, C. Increasing the rate of corrosion
D. Increasing the speed of the electrolyte
Correct Answer: Increasing the rate of corrosion
Rationale: Salts increase the conductivity of the electrolyte, allowing ions to move more easily and
thus accelerating the corrosion process.
Question 5: Coatings can control corrosion of steel by which of the following
mechanisms?
A. I only
B. II only
C. I and II only
D. I, II and III
Correct Answer: I, II and III
Rationale: Coatings protect via barrier effect (preventing electrolytes), sacrificial protection
(cathodic), and inhibition (passivating the surface).
Question 6: The vehicle of a coating consists of:
A. I only
B. II only
C. I, II and III
D. II and III only
Correct Answer: I only
Rationale: The vehicle includes the binder (film-former), solvent (liquefier), and any liquid additives
that remain part of the liquid phase.
Question 7: A typical daily report for a coating inspector should include:
A. III only
B. III and IV only
C. I, II, III, and IV
D. I, II, and III only
Correct Answer: I, II, and III only
Rationale: Reports must stick to facts: equipment, manpower, work stoppages, and ambient
conditions. Personal opinions of the contractor are not professional documentation.
Question 8: Solvents are added to coating formulations primarily to:
A. Dissolve binder and form a liquid coating
B. Provide color
C. Decrease film permeability
D. Increase film permeability
Correct Answer: Dissolve binder and form a liquid coating
Rationale: Solvents lower the viscosity of the binder, making it fluid enough for application by
spray, brush, or roller.
Question 9: The requirement for 5°F (3°C) above the dew point is to prevent:
A. Coating from curing too fast
B. Moisture vapor from condensing on the substrate
C. Solvent entrapment
D. Excessive dust accumulation
Correct Answer: Moisture vapor from condensing on the substrate
Rationale: Surface moisture (even invisible) can interfere with adhesion and cause premature
coating failure or flash rusting.
Question 10: A sling psychrometer directly measures which of the following?
A. Relative humidity
, B. Ambient temperature and wet bulb temperature
C. Substrate temperature and wet bulb temperature
D. Dew point
Correct Answer: Ambient temperature and wet bulb temperature
Rationale: The instrument has two thermometers: one dry (ambient) and one with a wet wick (wet
bulb). Other values like RH and Dew Point are calculated.
Question 11: According to NACE standards, the 'Dew Point' is defined as the
temperature at which:
A. Moisture vapor evaporates
B. Moisture vapor condenses
C. Moisture vapor increases
D. Corrosion is slowed down
Correct Answer: Moisture vapor condenses
Rationale: The dew point is the saturation temperature where air can no longer hold its water
vapor, resulting in condensation.
Question 12: Workers exposed to hazardous levels of free silica dust during abrasive
blasting may develop:
A. Liver disease
B. Heart failure
C. Lungs (Silicosis)
D. Stomach ulcers
Correct Answer: Lungs (Silicosis)
Rationale: Silicosis is a fibrotic lung disease caused by inhaling fine particles of crystalline silica,
typically from sandblasting.
Question 13: ISO 8503-1 comparators are available for which of the following abrasives?
A. Sand and Grit
B. Sand and Shot
C. Grit and Shot
D. All abrasive types
Correct Answer: Grit and Shot
Rationale: Comparators are specifically designed for 'G' (Grit/angular) and 'S' (Shot/round)
abrasive patterns.
Question 14: What is the primary advantage of ultra-high pressure water jetting over
abrasive blasting?
A. It creates a deeper anchor profile
B. It does not create a dust hazard
C. It removes tight mill scale more effectively
D. It is always cheaper
Correct Answer: It does not create a dust hazard
Rationale: UHP water jetting eliminates the airborne dust associated with dry abrasive blasting,
improving safety and environmental compliance.
Question 15: The cathode of a corrosion cell:
A. Dissolves in the electrolyte
B. Does nothing
C. Has an opposite electrical polarity to the anode
D. Is not considered to be part of the corrosion cell
Correct Answer: Has an opposite electrical polarity to the anode
Rationale: The cathode is the site where reduction occurs and is the more noble part of the cell
compared to the anode.
