Axiomatization Decision Log
1
Identity-Giving Function
Function class
FlameDetectionFunction
⊑ DetectionFunction
Realized in
FlameDetectionProcess
⊑ DetectionProcess
The identity-giving function is the detection of flames specifically. This is a specialization of the generic DetectionFunction already established for the Detector class, focusing on flame presence as the detected phenomenon.
2
Genus Determination
Detector
All source definitions explicitly state that flame detector is a type of detector. The Detector class is already enriched in our ontology with DetectionFunction and Assembly genus, making it the most specific appropriate superclass.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These are the essential components that every flame detector must possess - a specialized sensing element for flame detection and signal processing capability. The housing and other mechanical parts are inherited from the Detector genus.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
—
Outputs (O)
InformationContentEntity
— binary or analog signal indicating flame presence/absence
Transformation (T)
electromagnetic radiation detection and transduction to electrical signal
Flame detectors receive electromagnetic radiation characteristic of flames and convert this to electrical signals indicating detection status. The specific wavelengths depend on the sensing principle but all involve electromagnetic radiation from combustion processes.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Cross-Standard Observations
All three standards provide consistent functional definitions focused on flame sensing capability. ISO 15926 provides more detailed hierarchical context showing flame detector as both a detector and a flame detecting instrument. The sensing principle property from CFIHOS indicates the various technological approaches (infrared, ultraviolet, ionization) are constructive subtypes.
