Nonstructural component importance factor Ip = 1.5 for life-safety or hazardous-material components and components required for continued operation of a Risk Category IV facility; otherwise Ip = 1.0
Ip = 1.5 (scoped)observed
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | Ip is assigned according to the component’s function and failure consequences, not categorically to every component in every data center. It is distinct from the structural seismic importance factor Ie. |
