ICORR COATING INSPECTOR LEVEL 1 ONLINE
EXAM 2026 FULL TEST PAPER QUESTIONS AND
DETAILED ANSWER SOLUTIONS
◉ What is SSPC-SP 1? Answer: Standard for Solvent Cleaning
◉ What are the methods to supplement visual inspection? Answer:
Wipe Test, Ultraviolet Light test, Water-Break Test, or Dust Tape Test
◉ What are soluble salts? Answer: Primary focus when detecting
and removing non-visible contaminants.
◉ How are soluble salts commonly removed from surfaces? Answer:
Pressure washing or steam cleaning with clean water or salt
removing solution.
◉ What are the 5 tests for soluble salts? Answer: Potassium
Ferricyanide Test, Bresle Patch Test, Sleeve Test, Salt Meter,
Conductivity Test.
◉ What is the Potassium Ferricyanide Test? Answer: Qualitative test
for water ferrous salts on steel substrate.
,◉ What is the Bresle Patch Test? Answer: Common test to extract
soluble salts from surface and measure concentration.
◉ How does the Bresle Patch Test work? Answer: Soluble salt on
surface dissolves into water, fluid is extracted and conductivity is
measured.
◉ What is the Sleeve Test? Answer: Simple field test for
contamination with two variations.
◉ How is the Sleeve Test performed? Answer: One variation uses
titration tube, other uses colorimeter to determine results.
◉ What is a Salt Meter? Answer: Device to measure level of soluble
salts on a surface.
◉ How does a Salt Meter work? Answer: Measures the level of
soluble salts much faster than Bresle Patch Test.
◉ What is a Conductivity Test? Answer: Measures conductivity from
chloride, cannot indicate specific salts present.
◉ What does the Conductivity Test measure? Answer: Conductivity
from chloride ions.
,◉ What is SSPC Guide 15? Answer: Field methods for retrieval and
analysis of soluble salts on steel and other nonporous surfaces.
◉ What is SSPC Guide 24? Answer: Soluble salt testing frequency
and locations on new steel panels.
◉ What is NACE SP508? Answer: Methods of validating equivalence
to ISO 8502-9 on measurements of soluble salts.
◉ What is NACE SP 0716? Answer: Soluble salt testing frequency
and locations on previously coated surfaces.
◉ What is ISO 8502? Answer: Preparation of steel substrates before
application of paints and related products.
◉ What is ISO 8502 Part 2? Answer: Test for assessment of surface
cleanliness.
◉ What is ISO 8502 Part 5? Answer: Measurement of chloride on
steel surfaces prepared for painting - Ion detection tube method.
◉ What is ISO 8502 Part 6? Answer: Extraction of soluble
contaminants for analysis - The Bresle method.
, ◉ What is ISO 8502 Part 9? Answer: Field method for
conductometric determination of water-soluble salts.
◉ What is ISO 8502 Part 10? Answer: Field method for titrimetric
determination of water-soluble chloride.
◉ What is power tool cleaning? Answer: A method of surface
preparation using power tools.
◉ Can power tool cleaning create a uniform profile? Answer: No, it
cannot create a uniform profile like an abrasive would.
◉ Why is it important to taper or feather the edges of intact coating?
Answer: To provide a smooth transition for the new applied coating.
◉ What is a feathered edge? Answer: A gradual smooth slope
extending from old paint to substrate.
◉ What are the two categories of power cleaning tools? Answer:
Impact cleaning and rotary or grinding tools.
◉ Name some impact cleaning tools. Answer: Chipping/scaling
hammer, needle scaler, piston scaler.
