1 Identity-Giving FunctionFunção Identitária
Function class
ContainmentFunction ⊑ DesignedFunction
Realized in
ContainmentProcess ⊑ PlannedProcess
CFIHOS defines a chamber as 'an enclosed space' and ISO 15926 as an ENCLOSURE 'especially one inside an ARTEFACT'. The identity-giving function is containment, which COPI already declares as COPI_0000025.
2 Genus DeterminationDeterminação do Gênero
MaterialArtifactbfo:Object (BFO_0000030)
ISO 15926 types CHAMBER as an ARTEFACT and an ENCLOSURE; MaterialArtifact is the corresponding IOF root.
3 Differentia SpecificaDiferença Específica
∃bearerOf.ContainmentFunction ⊓ ∃componentPartOf.MaterialArtifact

A material artifact that bears a containment function and is an enclosed space located within a larger artifact.

Necessary-only. ContainmentFunction is borne by many things that are not chambers (vessels, tanks, pipelines); making this equivalent would pull all of them in. The interiority condition is what narrows it.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

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).
