32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Hold point
- A defined stage in inspection where work cannot proceed until the inspector has verified the required characteristic and documented acceptance.
- Witness point
- A notified inspection stage the inspector may observe; work may proceed if the inspector is absent, unless the contract states otherwise.
- Nonconformance report
- A record that identifies a condition not meeting specification, including location, requirement, objective evidence, disposition, and corrective action.
- Stop-work authority
- Contractual power allowing the inspector to halt nonconforming work; without it, the inspector documents and escalates rather than stopping the contractor directly.
- Instrument calibration check
- Verification that a test instrument is within calibration and functioning before readings are accepted; results are recorded with the inspection data.
- Volume solids
- The fraction of a coating that remains as dry film after solvent evaporates; used to calculate wet-film thickness and theoretical coverage.
- Zinc-rich primer
- A primer containing high zinc dust loading that protects steel cathodically and sacrificially; binder and zinc content must meet the specified coating standard.
- Recoat window
- The manufacturer-specified time range during which a subsequent coat will bond properly; exceeding it usually requires surface abrasion before recoating.
- Polyurethane topcoat
- A UV-resistant, chemically resistant finish often applied over epoxy; it is moisture-sensitive during cure and requires correct mixing and induction.
- Theoretical coverage
- The area a coating can cover at a given dry-film thickness, calculated as 1000 times volume solids divided by target dry-film thickness in micrometres.
- Near-white blast
- An abrasive blast cleanliness grade, SSPC-SP 10 or ISO Sa 2½, allowing only limited staining while removing nearly all mill scale, rust, and old coating.
- Dew point margin
- The required difference between substrate surface temperature and dew point, commonly at least 3°C or 5°F, to prevent condensation during coating.
- Bresle method
- A soluble-salt test using a patch and conductivity meter to estimate chloride contamination on a surface; results are reported in micrograms per square centimetre.
- Surface profile
- The roughness of an abrasive-blasted surface measured peak-to-valley; it improves mechanical adhesion and must match the coating manufacturer's range.
- White metal blast
- The highest abrasive blast cleanliness grade, SSPC-SP 5 or ISO Sa 3, with no visible oil, grease, rust, mill scale, paint, or foreign matter.
- Airless spray
- A spray method that atomizes coating by forcing it through a small tip at high hydraulic pressure, reducing overspray compared with conventional air spray.
- Stripe coat
- A brushed or rolled coat applied to edges, welds, corners, and back of angles before full spray application to ensure adequate coverage at difficult geometries.
- Plural-component spray
- Equipment that meters and mixes multiple coating components at the specified ratio and delivers the mixture to the spray gun before it cures.
- Wet-film thickness
- The thickness of a coating measured immediately after application; it is calculated by dividing target dry-film thickness by volume solids fraction.
- Spray overlap
- The amount each spray pass overlaps the previous pass, commonly about 50 percent, to produce a uniform film without skips or heavy build.
- Magnetic pull-off gauge
- A dry-film thickness instrument for ferrous substrates that measures the force needed to detach a magnet from the coating; readings are verified with foil shims.
- Eddy current gauge
- A non-destructive dry-film thickness instrument for nonferrous substrates that uses electromagnetic induction; it is not suitable for measuring coatings on steel.
- Holiday detector
- A test instrument that applies voltage across a coating to locate pinholes, cracks, or thin spots; voltage selection depends on coating thickness and specification.
- Pull-off adhesion test
- A quantitative adhesion test in which a dolly is bonded to the coating and pulled until failure; result and failure mode are recorded.
- Comparator disc
- A surface-profile reference tool with known roughness patterns used visually to estimate blast profile; replica tape gives a more objective measurement.
- Daily inspection report
- A record of date, location, weather, ambient conditions, surface temperature, dew point, work performed, readings, and inspector signature.
- Calibration certificate
- A document showing an instrument's calibration traceability; inspectors verify it is current and record instrument identification with test results.
- As-built coating record
- Final project documentation listing coating system, batch numbers, dry-film thickness map, repairs, nonconformances, and acceptance status for each area.
- Test report content
- A report stating the test method, acceptance criterion, measured result, pass or fail determination, location, date, instrument, and inspector.
- Confined space permit
- A written authorization for entry that specifies atmospheric testing, ventilation, rescue arrangements, attendant duties, and acceptable entry conditions before workers enter.
- Silica dust exposure
- Airborne crystalline silica from abrasive blasting or concrete grinding can cause silicosis; controls include respiratory protection, ventilation, and dust suppression.
- VOC content
- Volatile organic compounds in a coating that evaporate during cure; limits are regulated and compliance depends on product data and thinning practices.
