1 bounded physical-evidence record.
Publisher independence, identity precision and measurement scope vary by row. Results remain bounded by the disclosed specimen, setup, workload and metric; an inconclusive mapping is evidence associated with the catalog model, not verification of a manufacturer claim.

Known limits
What this record does not prove.
- No continuous torque is published in the cited specification.
- Ingress protection does not establish corrosion, dynamic-seal or connector performance in every medium.
- Stall torque and no-load speed cannot be combined into mechanical power.
