30 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Static pressure
- Pressure measured under the stated no-flow condition, distinct from the pressure available at an outlet during actual demand.
- Backsiphonage
- Unwanted reverse flow associated with reduced supply pressure, requiring assessment of the actual connection and contamination hazard.
- Backpressure
- A downstream pressure condition capable of driving fluid toward the potable supply through an unprotected relevant connection.
- Cross-connection
- An actual or potential connection between potable water and a nonpotable source that can create a contamination pathway.
- Thermal expansion vessel
- A designed component accommodating relevant fluid-volume increase, distinct from an independent temperature or pressure relief function.
- Stagnation
- Low-use or no-flow conditions that can affect water quality and require appropriate design, operation and hygiene assessment.
- Trap seal
- The retained water barrier in a suitable fixture trap that limits drainage gases entering occupied space under the actual system conditions.
- Air-admittance valve
- A device admitting air under specified negative-pressure conditions while closing otherwise, not providing every positive-pressure venting function.
- Backwater level
- The relevant design reference for possible sewer backup, used under the actual project and applicable drainage basis.
- Lifting plant
- Equipment raising wastewater to its intended discharge arrangement, dependent on actual capacity, control, protection and maintenance requirements.
- Cleanout
- An access provision for relevant inspection or maintenance of a drainage route, positioned and used according to the actual design.
- Hydraulic interface
- A connection where flow, pressure, geometry and the functions of adjacent system parts must be coordinated.
- Hydronic circuit
- A fluid circulation arrangement carrying heat through the relevant heating components, distinguished from potable-water distribution and its quality requirements.
- Condensing heat recovery
- Recovery of additional combustion-product heat through water-vapor condensation under suitable equipment and operating conditions.
- Combustion-air path
- The designed route providing appropriate air for an appliance, whose adequacy is not established by flame appearance alone.
- Room-sealed appliance
- An appliance arrangement drawing combustion air and discharging products through its designed external connections rather than ordinary room air.
- Gas regulator
- A device controlling relevant outlet gas pressure within its specified operating range, distinct from a shutoff or overpressure safeguard.
- Protective-function verification
- The competent documented assessment that relevant safeguards operate as required, separate from an ordinary command or visual appearance.
- Controlled revision
- The approved version of technical information for the actual task, preventing different workers from following incompatible dimensions, details or instructions.
- Datum
- A stated reference used to relate dimensions and locations consistently, rather than an arbitrary convenient edge selected independently for each part.
- Written dimension
- The specified physical size or relationship stated on a drawing, distinct from measuring a potentially rescaled printed image with a ruler.
- System boundary
- The chosen extent of a model or task that determines which inputs, outputs, forces and responsibilities are included in the reasoning.
- Measurement uncertainty
- A characterization of the possible dispersion associated with a measurement result, distinct from the instrument’s smallest display increment.
- Acceptance criterion
- A defined requirement used to judge appropriate evidence, which must not be replaced by an attractive appearance or an undocumented expectation.
- Hold point
- A defined stage requiring appropriate verification or approval before work proceeds and makes the relevant feature difficult or impossible to inspect.
- Change control
- An accountable process for assessing and approving a departure from specified information, rather than silently substituting a convenient product or method.
- Temporary stability
- The needed resistance to instability during an intermediate construction stage, which cannot be assumed from the completed structure’s final load path.
- Task-specific control
- A protective measure selected for the actual hazard, equipment, conditions and competence, rather than a universal glove, distance or generic PPE instruction.
- Net quantity
- The amount calculated for the defined work before separately specified allowances, which must use consistent dimensions and measurement conventions.
- Handover evidence
- Relevant records, observations, accepted conditions and unresolved issues communicated to the responsible recipient at completion, beyond a neat visible surface.
