ICorr COATING INSPECTOR LEVEL 1 (ONLINE INCLUDING MARINE &
OFFSHORE)
1. What is the primary purpose of a protective coating?
A. Improve appearance only
B. Prevent corrosion and deterioration
C. Increase metal hardness
D. Reduce metal weight
Answer: B
Explanation:
Protective coatings isolate steel from moisture, oxygen, salts, and
chemicals, significantly reducing corrosion.
2. Corrosion is best defined as:
A. Metal polishing
B. Electrochemical deterioration of metal
C. Heat expansion
D. Mechanical wear
Answer: B
Explanation:
Corrosion is an electrochemical reaction where metal returns to a more
stable oxide state.
,3. Which metal commonly requires protective coatings in offshore
structures?
A. Copper
B. Aluminum
C. Carbon steel
D. Titanium
Answer: C
Explanation:
Carbon steel is widely used offshore because of its strength but requires
coatings due to its susceptibility to corrosion.
4. Which environment is generally the most corrosive?
A. Desert
B. Indoor office
C. Marine splash zone
D. Mountain region
Answer: C
Explanation:
The splash zone experiences wetting, drying, oxygen exposure, and salt
deposits, accelerating corrosion.
5. Surface preparation mainly aims to:
A. Increase metal thickness
B. Remove contaminants and create a suitable profile
C. Reduce paint cost
D. Improve welding
Answer: B
Explanation:
Proper preparation ensures excellent coating adhesion and performance.
6. Which standard measures surface cleanliness after abrasive
blasting?
,A. ISO 8501-1
B. ISO 12944
C. ISO 9001
D. ISO 17025
Answer: A
Explanation:
ISO 8501-1 provides visual standards for assessing blast-cleaned steel.
7. Sa 2½ represents:
A. Hand cleaning
B. Thorough blast cleaning
C. White metal blast cleaning
D. Wire brushing
Answer: B
Explanation:
Sa 2½ removes nearly all rust, mill scale, and contaminants, leaving only
slight staining.
8. Which contaminant often causes premature coating failure?
A. Dust
B. Soluble salts
C. Moisture
D. All of the above
Answer: D
Explanation:
Each contaminant can significantly reduce coating adhesion and service
life.
9. The purpose of abrasive blasting is to:
A. Polish steel
B. Remove contaminants and create anchor profile
C. Heat steel
D. Apply primer
, Answer: B
Explanation:
Blasting cleans the surface and creates roughness for mechanical
adhesion.
10. Which instrument measures surface profile?
A. Hygrometer
B. Micrometer
C. Surface profile gauge
D. Gloss meter
Answer: C
Explanation:
Surface profile gauges determine anchor pattern depth after blasting.
11. Relative humidity should generally be below:
A. 95%
B. 85%
C. 50%
D. 20%
Answer: B
Explanation:
Many coating specifications limit RH to below 85% to reduce
condensation risk.
12. Dew point is:
A. Paint viscosity
B. Temperature where moisture condenses
C. Steel hardness
D. Air pressure
Answer: B
