Don't confuse yourself by using terms defined in one code or standard and 
applying that to another.
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...

[If I am wrong or missed something, someone will surely speak up (knowing the 
"forumites" who regularly post).]

Subject: Dwelling Unit- 13 vrs IBC defs

NFPA 13-'07 defines a dwelling unit in 3.3.7 and specifically calls out "For 
purposes of this standard, dwelling unit includes hotel rooms,..." and there is 
no requirement for cooking facilities.

2009 IBC in 202, Definitions, Dwelling Unit. 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).

Subject: RE: NFPA 25 standpipe test

You must flow the system demand at time of design (14:6.3.1.3 2008 ed). 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.

Subject: NFPA 25 standpipe test

I am working with a hospital with a total of 9 standpipes. 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.
