1 Identity-Giving FunctionFunção Identitária

SealingFunction ⊑ DesignedFunction

SealingProcess ⊑ PlannedProcess
The identity-giving function is sealing - preventing fluid or gas leakage between mating surfaces. All definitions consistently emphasize this sealing capability as the fundamental purpose that makes a gasket a gasket.
2 Genus DeterminationDeterminação do Gênero
MaterialArtifactbfo:Object (BFO_0000030)
No domain-specific superclass exists in the already-enriched classes. While ISO 15926 suggests 'SEAL' as a parent, this generic seal category is not yet defined in our ontology. Gaskets are typically monolithic deformable components (not assemblies with removable parts), making MaterialArtifact the appropriate BFO root.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.DeformableMaterial ⊓ ∃participatesIn.SurfaceSealingProcess ⊓ ∃hasProperty.ClosedLoopGeometry

A gasket is distinguished by being made of deformable material arranged in closed loops that seals between mating surfaces with limited relative movement.

The differentia captures the three key distinguishing characteristics: deformable material construction, closed-loop geometry, and specific application to low-movement surface interfaces. This distinguishes gaskets from other sealing components.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

Gaskets are typically monolithic components made entirely of deformable material. More specific part requirements (metal jackets, fillers, etc.) vary by subtype and should be modeled at those levels.

TransformationTransformação
geometric deformation to fill surface irregularities and create leak barrier
Gaskets transform the geometry of a joint by deforming under compression to fill gaps and create a continuous seal barrier between two mating surfaces.

Valve Pump Compressor
C4: Valve, Pump, Compressor. Gaskets are passive sealing components that undergo geometric deformation, incompatible with active flow control, pumping, compression, or powered sealing mechanisms.
