30 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Bend allowance
- The developed length assigned to a bend under a specified geometry and neutral-axis model, not automatically the outer arc length.
- Development
- The construction of a flat pattern corresponding to a formed part, accounting for actual geometry and required bend or seam allowances.
- Standing seam
- A raised sheet-metal joint arrangement whose actual geometry, movement and water performance depend on the specified roofing or cladding system.
- Neutral axis
- The modeled position in a bend with no longitudinal extension or compression, used under stated assumptions to estimate developed length.
- Galvanic compatibility
- Assessment of dissimilar material contact and relevant electrolyte exposure rather than assuming every metal combination performs alike.
- Thermal movement allowance
- A designed means to accommodate the component’s relevant temperature-related dimensional change while preserving support, weathering and attachment functions.
- Waterproofing continuity
- The coordinated connection of relevant layers and interfaces intended to manage water under the actual roof design and exposure.
- Emergency overflow
- A designed alternative water discharge route whose capacity and safe destination require actual project verification rather than a guessed dimension.
- Inverted roof
- A roof arrangement placing relevant insulation above the waterproofing layer, with system-specific loading, drainage and moisture considerations.
- Wind uplift
- An action tending to lift roof or facade components, requiring an actual load path and designed attachment or ballast.
- Membrane compatibility
- The suitability of adjacent membranes, adhesives, seams and accessories as a specified system rather than merely similar product labels.
- Maintenance access
- The planned safe means to inspect, clean, repair and replace relevant components while preserving required building functions.
- Ventilated rainscreen
- An enclosure arrangement separating external cladding from an inner protected assembly through a designed drained and ventilated cavity.
- BIPV
- Photovoltaic components integrated with a building-enclosure function, requiring both electrical and relevant structural/weather performance to be coordinated.
- Fixed point
- A designed restraint location controlling a panel’s reference position, coordinated with other supports and its specified movement accommodation.
- Sliding point
- A designed support allowing specified movement while transferring relevant forces under the actual panel and fixing system.
- Thermal break
- A lower-conductivity component reducing a particular heat-flow bridge without automatically eliminating all thermal or moisture risks.
- Temperature coefficient
- A stated rate of change of a PV quantity with cell temperature under a specified model, not an annual yield guarantee.
- 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.
- SMAW
- Shielded metal arc welding using a flux-coated consumable electrode, with actual classification and parameters governed by the relevant approved procedure.
- GMAW
- Gas metal arc welding using a continuously fed consumable electrode and appropriate external shielding under specified process conditions.
- GTAW
- Gas tungsten arc welding using a nonconsumable tungsten electrode, with separate filler added where the actual procedure requires it.
- Heat-affected zone
- Base material altered by welding heat without being melted as weld metal, with properties influenced by material and thermal history.
- Heat input
- A process-energy measure calculated using a stated formula and units, whose interpretation depends on whether efficiency and travel conditions are included.
- Interpass temperature
- The relevant temperature condition between weld passes, controlled according to the actual material and approved procedure rather than a universal number.
