24 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Heat-release rate
- The energy released per unit time in the stated fire model, distinct from total fuel energy or a material temperature.
- Flash point
- A defined test-related temperature associated with an ignitable liquid-vapor mixture, not a universal spontaneous-ignition temperature.
- Entrainment
- Addition of surrounding fluid into a moving plume or stream, which can increase total mass flow while reducing temperature.
- Design fire
- A specified scenario or mathematical representation used for an identified analysis objective, not a prediction guaranteed for every real fire.
- ASET
- Available safe egress time under the actual relevant criteria, limited by the earliest governing unacceptable condition in the stated analysis.
- RSET
- Required safe egress time under the chosen model, including its defined recognition, response and movement components rather than travel alone.
- Assembly continuity
- Maintenance of the intended protective boundary through actual joints, penetrations and openings, not merely the rating of one separate product.
- Tenability criterion
- A defined relevant condition used to assess an exposure or route objective, requiring appropriate assumptions and uncertainty treatment.
- Cause-and-effect matrix
- A defined relationship between initiating conditions, logic, outputs and feedback, used to assess actual coordinated system behavior.
- Local silence
- A product-specific acknowledgement or sound operation that must not be confused with removing the alarm cause or restoring every function.
- Impairment
- A condition reducing an intended protective capability, requiring the actual authorized management, communication and restoration process.
- Feedback evidence
- Information about the actual state or response of a field device, distinct from proof that a control command was merely sent.
- Residual pressure
- Pressure observed under the defined flowing condition, distinct from a static no-flow reading or proof of all possible demands.
- K-factor model
- A discharge relationship whose coefficient and pressure units must match the stated equation and output units before calculation.
- Waterflow indication
- A signal associated with observed flow under the actual device and arrangement, not independent proof of complete suppression effectiveness.
- Supply duration
- The time over which the defined demand must be sustained under the actual basis, distinct from achieving one instantaneous flow.
- Makeup air
- Replacement air entering a smoke-control arrangement, whose amount and velocity can affect extraction, pressure and plume behavior.
- Plugholing
- An undesirable exhaust condition drawing cleaner lower-layer air instead of the intended smoke, limiting effective removal under the actual geometry.
- Enclosure integrity
- The relevant leakage and boundary condition of a protected space, important to a defined retained concentration or pressure objective.
- Agent exposure
- The actual human contact with extinguishing agent and atmosphere, requiring appropriate safety assessment rather than assumptions from a clean-agent label.
- Acceptance basis
- The actual applicable requirements, criteria, conditions and method used to judge the evidence, identified before a compliance conclusion.
- Common dependency
- A shared component or condition that can defeat nominally separate protective paths and invalidate an independence assumption.
- Expected-loss screen
- A simplified calculation using stated probability and consequence, distinct from a complete life-safety or risk-distribution assessment.
- Restoration evidence
- Appropriate confirmation that the physical cause and intended protective functions have been addressed under the authorized process.
