The term is normally only good for that code or standard and are separate. Use the IBC definition when applying IBC rules and NFPA 13 definition when applying NFPA 13. I can go into detail/legal if you like but this brief explanation keeps it simple and to the point...

A single unit providing complete, independent living facilities for one or more persons, including permanent provisions for living, sleeping, eating, cooking and sanitation." So while the installation standard clearly states hotel rooms are intended to be protected as dwelling units, it seems that in order to qualify as dwelling units under the IBC, permanent cooking facilities must be present, and building codes trump installation standards. So does this mean when designing a system under #13 in a jurisdiction that adopted the IBC, we can't use dwelling unit rules from 13 in a hotel if the rooms don't contain a kitchen and bathroom? ] It may get cloudy when the IBC continues on to require QR or Residential sprinklers in Group R and I-1 dwelling units and sleeping units in 903.3.2 (2).

The flow test must occur at the hyd most remote outlets (14:6.3.1.2). You only need to do one flow test per zone (14:6.3.1.1). Your two sections do not necessarily mean two zones. Note also, if this is for Joint Commission, you will need to go back to the old codes. To my knowledge, they are enforcing NFPA 101 2000 edition...this means the 1998 edition of NFPA 14 is applicable.

There are standpipes that are both pre and post 1993. The original building is partially sprinklered and the new section is fully sprinklered. 1. Is the intent of NFPA 25 that multiple standpipes be flowed simultaneously to meet the 1250 gpm demand? 2. Should the two sections of the hospital be flow independent of each other? 3. If yes to 1 and 2, could the new section be flowed as a fully sprinklered building (thus 1000 gpm) as opposed to 1250? 4. How should i handle pipe schedule standpipes, if any exist? I haven't had to deal with 5 year standpipe tests before. Todd G.
