AMPP CIP Level 1 – Basic Coating Inspector
Theory Study Guide PDF | Certification Exam
Prep & Practice Questions.
Based on AMPP (formerly NACE) Coating Inspector Program Level 1 curriculum, here are
practice exam questions with correct answers and explanations in italic.
Question 1: Inspector Role & Responsibilities
What is the primary role of a coating inspector?
A) To apply coatings according to manufacturer specifications
B) To ensure quality control and specification compliance
C) To manage the project budget and timeline
D) To supervise the coating applicators
Correct Answer: B
The primary role of the coating inspector is to serve as a quality control function—
verifying that the coating system being installed complies with the project specification's
requirements . The inspector assesses and reports on technical aspects of the industrial
coating project and its conformance or deviation from specifications .
Question 2: Corrosion Fundamentals
What four components must be present for a corrosion cell to form?
A) Anode, Cathode, Electrolyte, Oxygen
B) Anode, Cathode, Metallic Pathway, Electrolyte
,C) Anode, Cathode, Water, Salt
D) Metal, Oxygen, Water, Temperature
Correct Answer: B
All four components of the electrochemical cell must be present for corrosion to occur: the
anode (where oxidation/corrosion occurs), the cathode (where reduction occurs), the
metallic pathway (allowing electron flow from anode to cathode), and the electrolyte (a
conductive medium allowing ion transfer) . The electrolyte is typically water or moisture
that conducts ionic current .
Question 3: Surface Preparation Standards
SSPC-SP 10 corresponds to which NACE standard?
A) NACE No. 1
B) NACE No. 2
C) NACE No. 3
D) NACE No. 4
Correct Answer: B
SSPC-SP 10 (Near-White Blast Cleaning) corresponds to NACE No. 2. The numerical order
is: SP5/NACE No. 1 (White Metal), SP10/NACE No. 2 (Near-White), SP6/NACE No. 3
(Commercial), SP14/NACE No. 8 (Industrial), and SP7/NACE No. 4 (Brush-Off) .
Question 4: Coating Composition
Which coating component forms a stable film and retains its characteristic
properties?
A) Pigment
B) Solvent
C) Binder/Resin
D) Additive
,Correct Answer: C
The binder (also called resin) is the film-forming component of a coating that bonds
pigments together and adheres to the surface, forming a stable film that retains its
characteristic properties . Pigments provide color and hiding properties, solvents dissolve
the resin, and additives enhance specific performance characteristics .
Question 5: Inspection Process
What should an inspector do if they find discrepancies between the project
specification and the coating manufacturer's Product Data Sheet (PDS)?
A) Follow the PDS since it comes from the manufacturer
B) Follow the specification since it is contractually binding
C) Seek clarification from the owner's representative during the pre-job conference
D) Make an independent decision based on experience
Correct Answer: C
When discrepancies exist between specifications and manufacturer documentation, the
inspector should seek clarification from the owner's representative (or project engineer)
during the pre-job conference. This ensures proper resolution before work begins .
Question 6: Environmental Conditions
What is the minimum recommended substrate temperature relative to the dew
point for coating application?
A) At least 5°F (3°C) above the dew point
B) At least 10°F (5°C) above the dew point
C) At least 3°F (1.5°C) above the dew point
D) Equal to the dew point
Correct Answer: A
, The substrate temperature must be at least 3°C (5°F) above the dew point temperature to
prevent moisture condensation on the surface, which would compromise coating adhesion
and cause defects . This is typically measured and recorded as the "Delta" (Δ) value.
Question 7: DFT Measurement
When using a magnetic pull-off DFT gauge, what is the minimum distance from
the edge where measurements should be taken?
A) 1/2 inch
B) 1 inch
C) 2 inches
D) 3 inches
Correct Answer: B
Measurements with magnetic pull-off DFT gauges should be taken at least 1 inch from
edges to avoid edge effects that can produce inaccurate readings .
Question 8: Coating Inspection Standards
Which standard addresses measurement of Dry Film Thickness (DFT) with
magnetic gauges?
A) NACE SP0188
B) ASTM D4417
C) SSPC PA-2
D) SSPC SP-10
Correct Answer: C
SSPC PA-2 is the standard that covers procedures for measuring dry film thickness with
magnetic gauges. NACE SP0188 covers holiday testing, and ASTM D4417 covers surface
profile measurement methods .
