Semi-formal axiom (Aristotelian)
Axiom type
LLM classification basis: function-based → ≡
All definitions consistently define flare by its function: burning waste gas for safe disposal. The identity is given by the WasteGasDisposalFunction it realizes, not by a specific physical mechanism. Different flare implementations (boom, tower, tip) can realize this same function.

Identity-Giving Function
✓ done
WasteGasDisposalFunction → WasteGasDisposalProcess ⊑ ChemicalReaction
▼
COPI-Core operation
ChemicalReaction via process parent ChemicalReaction
LLM rationale:
The identity-giving function is the safe disposal of unwanted/waste gases through controlled combustion. This distinguishes flares from other burners which may burn fuel for heating or other purposes.

Genus Proximus

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
ISO 15926 explicitly states 'A FLARE is a BURNER that has a capability of FLARING'. Burner is the most specific superclass - it's more precise than generic Assembly. A burner has causal unity as a single combustion device but consists of removable parts (tip, pilot, controls), making it an Assembly rather than monolithic MaterialArtifact.

Conditions that distinguish
Flare
from sibling classes under genus
Burner.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
The differentia is the specific waste gas disposal function. All sources emphasize disposal of 'unwanted', 'waste' gases, distinguishing flares from burners used for productive combustion.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
These three parts are universal to all flare types: tip (combustion), stack (safe positioning), pilot (ignition). Additional parts like knock-out drums or distribution systems are subtype-specific.

Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Flare signature is waste gas input transformed through combustion to safer output products, enabling safe disposal of materials that cannot be processed or stored.
