AMPP/NACE Coating Inspector Program Level 2 Exam (CIP Level 2)
SUMMARIZED EXAM COVERAGE
The AMPP/NACE CIP Level 2 certification is an advanced credential for coating inspectors who have
completed Level 1. The course focuses on advanced inspection techniques, specialized application
methods, and non-destructive/destructive testing . Key domains include: advanced surface preparation
standards (NACE/SSPC, ISO, WJ), centrifugal blast cleaning, waterjetting classifications (LP, HP, UHP),
thermal spray and metallizing, rubber linings and vulcanization, pipeline coatings (FBE, CTE, 3LPE, heat
shrink sleeves), concrete surface preparation and testing, coating application methods (electrostatic
spray, flow/flood), inspection documentation and report writing, and relevant NACE/AMPP/SSPC/ASTM
standards .
1. The concentrated area of blast created by a centrifugal blast machine is called the what?
A) Hot spot
B) Impact zone
C) Blast cone
D) Centrifugal field
Answer: A
, Page 2 of 110
Rationale: The concentrated area of blast created by a centrifugal blast machine is known as the "hot
spot," where cleaning action is most intense .
2. What could be the cause of low amperage readings on a centrifugal blast machine?
A) Oversized abrasive media only
B) An abrasive-starved wheel or a flooded/choked wheel
C) High belt speed only
D) Low voltage supply to the motor
Answer: B
Rationale: Low amperage typically indicates either insufficient abrasive reaching the wheel (starved) or
too much abrasive causing choking .
3. In a centrifugal blast operation, the degree of cleanliness is determined primarily by:
A) Abrasive size
B) Speed of travel
C) Wheel speed only
D) Number of passes
, Page 3 of 110
Answer: B
Rationale: The speed of travel controls the exposure time of the surface to the blast stream, directly
impacting cleanliness levels .
4. What is one advantage of portable centrifugal blast cleaning?
A) It cannot be used on vertical surfaces
B) Abrasives cannot be recycled
C) Dust can be collected for disposal and abrasives can be recycled
D) It only works on flat horizontal surfaces
Answer: C
Rationale: Portable centrifugal blast systems offer environmental benefits through dust collection and
economic benefits through abrasive recycling .
5. True or False: Abrasive blast machines clean best with a range of abrasive sizes rather than a single
size.
A) True
B) False
, Page 4 of 110
Answer: A
Rationale: A mix of abrasive sizes provides better surface coverage and cleaning efficiency than a single
uniform size .
6. What is the pressure range for High-Pressure Water Cleaning (HP WC)?
A) Below 5,000 psig
B) 5,000 to 10,000 psig
C) 10,000 to 30,000 psig
D) 30,000 psig and above
Answer: B
Rationale: High-Pressure Water Cleaning operates between 5,000 and 10,000 psig, distinguishing it from
low-pressure and ultrahigh-pressure categories .
7. What is the typical pressure range for Ultrahigh-Pressure Waterjetting (UHP WJ)?
A) 5,000 to 10,000 psig
B) 10,000 to 20,000 psig
