AMPP / NACE CIP Level 1 Coating Inspector
Program Master Study Guide & Examination PDF
Exam Coverage Summary
This exam comprehensively covers the foundational knowledge required for the AMPP/NACE
CIP Level 1 Coating Inspector. The primary domains include the inspector's role and safety
protocols, understanding and using inspection instruments and testing equipment, surface
preparation standards and methods, environmental conditions and their effects, coating
application methods and procedures, and coating types and their properties. It also encompasses
the principles of corrosion, the importance of specifications and documentation, and critical
elements of quality control and assurance.
1. A coating inspector's primary duty regarding safety on a job site is to:
a) Report any unsafe conditions to the site supervisor immediately.
b) Enforce all safety regulations and stop any unsafe work.
c) Ensure their own safety and that of others by observing and reporting hazards.
,2
d) Wear all required PPE but not interfere with the work crew.
Rationale: The inspector's role is to observe, report, and document safety hazards, but
enforcement is typically the responsibility of the site safety officer or supervisor, though stopping
work may be necessary in imminent danger. The key is to report and document.
2. The primary purpose of a coating specification is to:
a) List the supplier's warranty information.
b) Define the project's budget and timeline.
c) Define all the technical requirements for the coating system and its application.
d) Provide a guide for selecting the cheapest coating.
Rationale: A coating specification is a detailed document that outlines all the technical
requirements, including surface preparation, application methods, environmental limits, and
inspection criteria, to ensure the work is performed correctly.
3. When using a wet film thickness gauge, the reading should be taken:
a) Immediately after the solvent has flashed off.
b) Before the coating is applied.
c) Immediately after the coating is applied, while it is still wet.
d) After the coating has fully cured.
Rationale: Wet film thickness (WFT) must be measured immediately after application to confirm
,3
the applicator is using the correct technique and to calculate the expected dry film thickness
(DFT) before the coating begins to cure and evaporate.
4. The term "dew point" is best defined as the temperature at which:
a) Water vapor begins to evaporate.
b) Air becomes saturated with water vapor and condensation forms.
c) Surface temperature equals the air temperature.
d) The relative humidity reaches 50%.
Rationale: The dew point is the critical temperature at which air can no longer hold all its water
vapor, leading to condensation. Coating application must be avoided when the surface
temperature is within 3°C (5°F) of the dew point.
5. SSPC-SP 10/NACE No. 2 defines a surface preparation standard known as:
a) Near-White Blast Cleaning.
b) Commercial Blast Cleaning.
c) Brush-Off Blast Cleaning.
d) Power Tool Cleaning.
Rationale: SSPC-SP 10 is the standard for Near-White Blast Cleaning, which requires at least
95% of the surface to be free of visible mill scale, rust, and coatings, with the remaining 5%
being slight discoloration.

6. A holiday in a coating is best described as:
a) A color mismatch in the finish coat.
b) An area of excessive film thickness.
c) A discontinuity or pinhole in the coating film.
d) A run or sag in the coating.
Rationale: A holiday is a term for any discontinuity, such as a pinhole, void, or bare spot, in a
coating film that can allow corrosive elements to reach the substrate, significantly reducing the
coating's protective life.
7. On a magnetic pull-off DFT gauge, what does a "pull-off" reading measure?
a) The force required to pull a magnet from the coated surface.
b) The electrical resistance of the coating.
c) The thickness of the coating using eddy currents.
d) The adhesion strength of the coating.
Rationale: A magnetic pull-off gauge operates by using a magnet that is placed on the coating.
The force required to pull the magnet away from the steel substrate is calibrated to indicate the
thickness of the non-magnetic coating.
8. Chalking is a coating failure characterized by:
a) The formation of blisters under the coating.
