NACE CIP LEVEL 1 PRACTICAL EXAM WITH ALL
CORRECT & 100% VERIFIED ANSWERS|UPDATED
TO PASS
NACE SP0188 ✔Correct answer-High and Low Voltage Holiday Testing
Low-Voltage Holiday Detector ✔Correct answer--Ground is attached directly to substrate.
-Sponge saturated with a solution of tap water/wetting agent
-Proper mix ratio 1oz/USgal
-Proper of speed is 1ft/sec Double Stroke
-Used on Coatings up to 20mils
-may be used on concrete
Low Voltage Holiday Detectors Common Errors ✔Correct answer--Failure to Keep probe in contact with
surface
-Moving the electrode too fast or slow
-Over or under saturating the sponge
-Low battery or bad lead/ground connection
Telegraphing ✔Correct answer-Can occur when surface is saturated with water and the Detector reads a
different area.
High Voltage Holiday Detectors ✔Correct answer--Can have an Output range from 800-60,000v
-In General Voltage ratio 100v/1mil
-Electrode Rate of 1ft/sec with a single pass
-Ground connection must be made direct to metal substrate(preferred) or indirectly for pipeline in soil.
High Voltage Holiday Detector Pannel ✔Correct answer--When determining the Voltage used, if not shown on
dial use Voltage immediately below what's needed
-Remember the selection must be either High or Low and the corresponding number next to the Voltage.
SSPC-PA2 ✔Correct answer-Dry Film Thickness Gauge
SSPC-PA2 Type 1 ✔Correct answer-Magnetic Pull-Off DFT Gauge
-Dial-Type Magnetic Pull-Off DFT Gauge (Banana Gauge)
-Pencil Type Magnetic Pull-Off DFT Gauge
Dial TypeMagnetic Pull-Off DFT Gauge ✔Correct answer--Known as "Banana Gauge"
-Intrinsically Safe
-Some Models Can Be Used Underwater
ASTM D 7091 ✔Correct answer--Calibration: Gauge Shall be Calibrated by manufacturer or third party lab.
-BMR: In order to compensate for any effects from the blast profile must calculate the Base Metal Reading.
-Verify Accuracy: Use certified metal plates and Gauge must be within 5% of expected range.
Type 1 DFT Gauge Adjustment ✔Correct answer--Take 10 reading on the blasted steel surface and average
the results.
-Take DFT measurements
- Subtract BMR from DFT Averages
Type 1 DFT Gauge Potential Errors ✔Correct answer-DO NOT Use Gauge:
