CIP Level 1 Practical Exam Questions
and Complete Solutions Graded A+
Station 1 (Environmental Conditions) Duties - Answer: - Use sling psychrometer to measure wet and dry
bulb temperature
- Lookup in table (first using dry bulb) the relative humidity and dew point
- Record surface temperature
- Record if safe to coat (if difference is greater than 3 degrees celsius)
Station 2 (Profile) Duties - Answer: - Use the provided two-sided metal sheet for analysis
- First, use the surface profile comparator and magnifying glass to read the closest profile reading of
provided sheet (both sides)
- Second, use Testex tape to take two readings of the surface (both sides) and record value using a
spring-loaded micrometer. Stick tape to test. If value falls between 1.5-2.5 mils, use other tape and test
again.
- Third, zero the 224 Gauge using a piece of glass.
- Forth, use the 224 Gauge (orange, surface profile gauge) to take 20 readings (10 each side) on both
sides of the sheet (total 40 readings).
- Take averages of Testex tape and 224 Gauge readings for each side of the sheet.
Station 3 (Hi-Voltage) Duties - Answer: - Know how to safely use a Hi-Voltage Holiday Detector.
- Know Standard 0188.
- Know the five things.
Station 4 (Type 1 Gauge) Duties - Answer: - Verify the Type 1 Gauge. Take one DFT reading of the
finished topcoat, and pick a block in orange book nearest to value. Record values.
- Take 10 BMR (bare metal readings). Record.
- Take 15 readings of primer. Record.
- Take 15 readings of top coat. Record.
, Station 5 (Low Voltage Holiday Detector) Duties - Answer: - Should already be attached and grounded to
plate.
- Move the detector around the plate to locate holidays. Check edges. Plate will be flat. Dig for them.
- Answer questions (5 points).
Station 6 (Wet Film Thickness) Duties - Answer: - Pick up the comb gauge, highest notch with coating on
it is the recorded WFT (wet film thickness)
- Wet to dry conversion calculation (given SBV)
- Calculate how much coating do you need
- If told solvent, it does not impact amount of paint
Station 7 (Type 2 Gauge) Duties - Answer: - Verify the PosiTector, take a reading of the topcoat
- Select a single shim with a thickness at or close to the reading and record thickness value of the shim.
- If the readings do not match, increase or decrease until it matches the shim's measured thickness.
Repeat to ensure it matches.
- Take 15 primer readings, 5 locations with 3 spot readings (both sides)
- Take 15 topcoat readings, 5 locations with 3 spot readings (both sides)
Section 8 (Soluble Salt Detection) Duties - Answer: - How to do a Bresle Test
- How to do a Sleeve Test
- Know the indicated slides
What is a Holiday? - Answer: Holidays are an exposed area or discontinuity within the coating film where
part of the substrate remains uncoated.
What type of Holiday Detector to use? - Answer: The type of holiday detector used is based on the total
thickness of the coating system and the environment in which it is used.
What standard govern the use of holiday detectors? - Answer: NACE SP0188 Discontinuity (Holiday)
Testing of New Protective Coatings on Conductive Substrates
