Read what the reference hub claims to conform to
A device publishes its conformance claim with a pointer to a report. The reference hub claims the executor class, self-declared, with no report attached; its capability document and safety-limits pack say the same about what it is.
Leia primeiro: /docs/CORE/ /docs/HUB/
Passos
One claim, executor, and no report: the hub says so itself rather than implying a certification.
conformanceThe capability document lists the same role and a self-declared ISO 10218-1 certification entry.
capabilitiesThe safety-limits pack is the draft default; its status field says draft and its disclaimer says makers must replace it.

Resultado
You can read a claim and tell self-declaration from a report. Next: scenario 054 checks signatures, which is how a report would be trusted.
