Axiomatization Decision Log
1 Identity-Giving Function
Function class
GasDetectionFunction ⊑ DesignedFunction
Realized in
GasDetectionProcess ⊑ MeasurementProcess
ISO 15926 defines it as a MEASURING ELEMENT 'for the detection of the presence of a specified concentration of a gas' — a purely functional specification.
2 Genus Determination
MeasuringElement
ISO 15926 states the genus explicitly: it is a MEASURING ELEMENT, defined independently of the instrument handling the measurement.
3 Necessary Parts

No necessary parts recorded (concept may be primitive at this level).

No sub-component is named in any source definition for this term. validate_necessary_parts_quotes() requires a verbatim source_quote for every part, and there is nothing to quote — so no parts are asserted (ODR-022 §10.2).
4 Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfGas — sampled atmosphere or process gas whose composition is sensed
Outputs (O)
CompositionMeasurementResult — indication of whether the specified gas concentration is present
Transformation (T)
transduction of gas concentration into a detectable indication
Input is the gas being sensed, output is information content — the measurement result, not a material entity (ODR-010 §3).
5 Axiom Mode Decision

Necessary conditions only — modelled as a primitive universal (⊑, SubClassOf). Identity is grounded in designed function and cannot be reduced to a property checklist.

GasDetectionFunction is already the sufficient condition for the 'gas detector' instrument. A measuring element bears it as a component; parthood is not a sufficient condition.
Reviewer Notes
ODR-022 §O6: standard-term component of 'gas detector'. Admitted to the pipeline because it is a term in a source standard AND that standard states it is a component of that equipment (verbatim source_quote in the owning entry). Awaiting expert review. Definition reworded 2026-10-03 (pre-deposit copyright review, second pass).
