ICC flashcards
ICC · 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.
- Criterion-referenced exam
- An exam scored against a fixed passing standard rather than against other candidates' results; passing means meeting the minimum competency cut score.
- Scaled score
- A transformed score placed on a common reporting scale so that forms of different difficulty yield comparable results against the same cut score.
- Modified Angoff method
- A standard-setting procedure in which subject-matter experts estimate the probability that a minimally competent candidate answers each item correctly; the sum sets the cut score.
- Point-biserial discrimination
- A statistic measuring how well an item separates high-scoring from low-scoring candidates; low or negative values flag items for review.
- Standard error of measurement
- A statistic quantifying the uncertainty around an individual's observed score, indicating how much scores would vary across repeated testing.
- Exam blueprint
- A table of specifications that weights content domains by job-task frequency and criticality; domain weights sum to 100 percent and guide item counts.
- Reliability versus validity
- Reliability is the consistency of scores across forms and occasions; validity is whether the exam actually measures the intended knowledge and skills.
- Concrete cylinder acceptance
- Per ACI 318, averages of three consecutive 6x12 inch cylinder tests must equal or exceed f'c, and no single test may fall below f'c minus 500 psi.
- Slump test
- A field test performed per ASTM C143 that measures the workability and consistency of fresh concrete; it does not directly measure strength.
- Air content testing
- Fresh concrete air content is measured by the pressure method (ASTM C231) or the volumetric method (ASTM C173) to verify freeze-thaw durability.
- Turn-of-nut pretensioning
- A high-strength bolting method in which a specified rotation of the nut after snug-tight condition develops the required bolt tension; rotation depends on bolt length and diameter.
- AWS D1.1
- The structural welding code for steel, governing welder qualification, procedure qualification, and weld acceptance criteria for structural steel fabrication and erection.
- Relative compaction
- Field dry density divided by the laboratory maximum dry density, expressed as a percentage, used to verify soil compaction against specification.
- Liquid penetrant testing
- A nondestructive method that reveals surface-breaking defects in nonporous materials by applying a penetrant and developer to draw it out.
- Spill bucket test
- A test verifying that the spill containment bucket at a UST fill point is liquid-tight and free of liquid and debris.
- Overfill prevention
- A device such as a ball-float valve or drop tube that stops product flow at approximately 90 percent of tank capacity to prevent overfilling.
- Interstitial monitoring
- A release detection method that monitors the space between the primary and secondary walls of a double-walled tank or piping system.
- Cathodic protection potential
- A structure-to-soil potential of at least -850 mV measured with respect to a copper-copper sulfate reference electrode indicates adequate protection for steel.
- 40 CFR Part 280
- The federal UST regulation covering release detection, spill and overfill prevention, corrosion protection, and closure; state programs may be more stringent.
- AST dike capacity
- Secondary containment volume typically sized to hold 110 percent of the largest tank's capacity plus displacement from other tanks in the containment area.
- Concrete volume in cubic yards
- Multiply length times width times depth in feet, then divide by 27 to convert cubic feet to cubic yards.
- Ohm's law
- The relationship E = I x R, where voltage equals current times resistance; power in a resistive circuit equals I squared times R.
- OSHA fall protection trigger
- Fall protection for general construction is required at 6 feet, for scaffolds at 10 feet, and for ladders at 24 feet.
- Roof pitch
- Rise over run expressed as inches of rise per 12 inches of horizontal run; a 4/12 pitch rises 4 inches per foot.
- Critical path method
- A scheduling technique identifying the longest sequence of dependent activities; delay on the critical path delays project completion.
- Retainage
- A percentage, commonly 5 to 10 percent, withheld from progress payments until substantial completion to protect the owner.
- Combination designation
- A credential certifying the holder across multiple disciplines, with each discipline's exam and continuing education tracked separately.
- More restrictive provision
- The rule applied when disciplines conflict: the more stringent code requirement governs unless the authority having jurisdiction rules otherwise.
- Authority having jurisdiction
- The governmental body or official responsible for enforcing code and approving permits and inspections; it determines precedence in cross-discipline conflicts.
- Special inspections trigger
- Special inspections are typically required when the structural engineer of record issues a statement of special inspections identifying the required inspections.
- Continuing education allocation
- Combined credential holders must satisfy each discipline's minimum continuing education hours; hours are tracked per discipline for audit.
- Integrated scenario item
- A combined-exam question type requiring the candidate to apply multiple disciplines to one project condition and identify the governing code.
