AMPP CIP Level 1 flashcards
AMPP CIP Level 1 · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Hold point
- A stage in coating work that cannot proceed until the inspector has inspected and released it, as defined by the contract or inspection plan.
- Witness point
- A stage the inspector is notified to observe; if the inspector does not attend, work may proceed under the contract terms.
- Dew point
- The temperature at which air becomes saturated and water vapor condenses; steel must be above it before coating.
- Quality assurance
- The planned system of activities that ensures coating work meets specified quality requirements; often performed by the owner or inspector.
- Quality control
- The contractor's operational activities that measure and control coating quality, such as checking surface preparation, thickness, and environmental conditions.
- SDS
- Safety Data Sheet; a document listing chemical hazards, safe handling, PPE, first aid, and spill response for a coating product.
- Confined space
- An enclosed area with limited entry and exit and poor ventilation that may contain hazardous atmospheres; entry requires testing and permit controls.
- Nonconformance report
- A written record of work that does not meet specification, including location, description, and required corrective action.
- White metal blast
- SSPC-SP 5/NACE No. 1 blast cleaning that removes all visible rust, mill scale, coating, and foreign matter, leaving a uniform gray surface.
- Near-white blast
- SSPC-SP 10/NACE No. 2 blast cleaning that leaves only very light staining, limited to no more than 5% of each unit area.
- Commercial blast
- SSPC-SP 6/NACE No. 3 blast cleaning that removes at least two-thirds of visible contaminants, allowing staining on up to 33% of the area.
- Surface profile
- The angular roughness of a prepared steel surface, usually 1.5–4 mil (38–100 µm), which improves coating adhesion by increasing surface area.
- Replica tape
- A foam tape pressed against a blasted surface to imprint the profile; the compressed tape is measured with a micrometer.
- Bresle patch
- A sealed patch used to extract soluble salts from a surface; the extract's conductivity indicates chloride or salt contamination.
- Solvent cleaning
- SSPC-SP 1 cleaning that removes oil, grease, dirt, and soluble contaminants before hand, power, or blast cleaning.
- Mill scale
- A thin oxide layer formed on hot-rolled steel during cooling; it is cathodic to steel and must be removed before coating.
- Wet film thickness
- The thickness of a coating immediately after application; calculated as dry film thickness divided by the volume solids fraction.
- Volume solids
- The percentage of a liquid coating that remains as dry film after solvent evaporation; used to calculate wet film thickness and coverage.
- Pot life
- The maximum time after mixing during which a plural-component coating remains usable; exceeding it causes thickening and poor application.
- Induction time
- The required waiting period after mixing before application, allowing chemical components to react and the coating to reach proper application viscosity.
- Recoat window
- The time after application during which the next coat can be applied without surface preparation; outside it, the surface may need roughening.
- Stripe coat
- A brush-applied coat on edges, welds, corners, and irregular areas before full spray application to ensure adequate coverage.
- Airless spray
- A spray method that forces coating through a small tip at high pressure, forming a fan without compressed air.
- Mud cracking
- A network of cracks in a coating caused by excessive film thickness or rapid solvent loss, often resembling dried mud.
- DFT gauge
- An instrument that measures dry coating thickness using magnetic, eddy-current, or ultrasonic principles depending on substrate and coating.
- SSPC-PA 2
- A standard practice for measuring dry film thickness, defining spot measurements, area averages, and acceptance limits for coating work.
- Holiday test
- A test that detects discontinuities, pinholes, or thin spots in a coating using low-voltage wet sponge or high-voltage spark methods.
- Pull-off adhesion
- ASTM D4541 test that bonds a dolly to the coating and measures the force required to detach it, reporting strength and failure mode.
- Cross-cut adhesion
- ASTM D3359 test that cuts a lattice through the coating, applies tape, and rates the amount removed on a 0–5 scale.
- Calibration record
- Documentation of an instrument's calibration date, reference standard, and results, used to demonstrate measurement traceability.
- Daily report
- A record of coating work including date, weather, environmental readings, surface preparation, application, inspection results, and personnel.
- Nonconformance
- A condition where work fails to meet specification; it is documented, corrected, and re-inspected before acceptance.
