Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
FlameArrestFunction ⊑ DesignedFunction
Realized in
FlameArrestProcess ⊑ PlannedProcess
The identity-giving function is flame arrest - preventing flame propagation from entering a system through an opening. This is a specific safety function that distinguishes flame arrestors from other safety devices or flow control equipment.
2 Genus DeterminationDeterminação do Gênero
MaterialArtifactbfo:Object (BFO_0000030)
No appropriate domain superclass exists in the parent candidates. While 'ARRESTOR' appears in the hierarchy, it's too generic. 'ARTEFACT' is too broad. The concept requires a new intermediate genus 'SafetyDevice' for protective equipment, which would be a MaterialArtifact since flame arrestors are typically unitary devices installed in piping systems.
3 Differentia SpecificaDiferença Específica
∃bearerOf.FlameArrestFunction ⊓ ∃participatesIn.FlameArrestProcess

Bears a flame arrest function and processes gaseous flows while preventing flame propagation.

The differentia specifies the flame arrest function and gas flow processing capability that distinguishes this from other safety devices under the same genus.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These are the minimal essential parts - the functional arrest element and the structural housing to contain it and connect to the system.

OutputsSaídas

TransformationTransformação
flame arrest - heat dissipation and momentum loss to extinguish flame fronts
Flame arrestors process gas flows by removing flame fronts while allowing normal gas passage. The transformation is specifically flame extinguishment through physical mechanisms.
Disjoint WithDisjunto com
FlameDetector
C4: FlameDetector. Incompatible process signatures - flame arrestors extinguish flames while detectors sense them and igniters create them.
