Study Notes

Exam: NACE-CIP1-001

Title: Coating Inspector Level 1
Version: V8.02

Coating Inspector Actions

Blistering: If you are a NACE Inspector and see blisters in an epoxy tank lining, document the problem and inform the contractor and owner.
Dew Point: Dew point is the temperature at which condensation occurs.
Compressor Maintenance: If a poorly maintained compressor is used for abrasive blast cleaning, a wet film thickness (WFT) measurement, blotter test for oil and water, is needed.
Coating Material Arrival: Upon receiving coating materials, review vendor plans to ensure compliance with national, local, and owner's fire and environmental regulations, recording material amounts and batch numbers. Time frames and environmental conditions must also be observed between coats.
Relative Humidity: Relative humidity is a measure of the amount of moisture present in the air compared to the saturation level.
Galvanic Corrosion: Galvanic corrosion can occur on metals.

Coatings

Dry Film Thickness (DFT) Gauge: When measuring with a dial-type magnetic pull-off gauge, maintain a minimum distance of 2.5 cm (1 inch) from the edge.
Polymerization: Polymerization is the process of monomers joining together.
Poor Application Technique: Poor application technique can be manifested as cracking or holidays, both involving exposed substrate or previous coatings.
Checking: Checking are fine cracks that do not typically reach the substrate.
Holiday: A very small hole in a coating.

Additional Information

Instrument Calibration: NACE Inspectors should have instrument calibration certificates available.
Non-Conformance Reports: Non-conformance reports must be completed when items do not meet specifications.
Steel Condition: The initial steel condition (e.g., pitting, mill scale) impacts the coating requirements.
Corrosion: Galvanic corrosion is a serious type of corrosion.

Other Key Terms and Concepts

Inspection Documentation: The importance of thorough documentation, which owners use for various purposes.
Compressed Air Cleanliness: Need a specific blotter test to assess this
