UFC 3-600-01 4-2.3.1 Sprinkler Density and Hose Stream Requirements.   

Building and structures requiring sprinkler protection must be provided with 
sprinkler systems that are designed using the Area/Density Method of NFPA 13, 
\2\ except  the design density, design area, hose stream allowance and duration 
of supply requirements for non-storage occupancies must be in accordance with 
FM Global Loss Prevention Data Sheet 3-26, Fire Protection Water Demand for 
Non-Storage Sprinklered Properties Tables 1 through 4, including the revised 
Table 2 in FM Engineering Bulletin 04-12.  /2/

I'll give you they say area/density and NFPA 13 11.2.3.2 says density/area but 
they mean the same thing.  Small room falls under the next section 11.2.3.3 
Room Design Method.  UFC does not refernce you to 11.2.3 Water Demand 
Requirements - Hydraulic Calculation
Methods. Which would get you density/area, room design and special areas.

Maybe I'm not sure what Greg is asking, but we use small room all the time on 
UFC jobs and have never been called on it. Chris could you point me to where it 
says you can't use small room?

IDK about FM.  UFC is clear to me, no you can't use small room - area/density 
only, and no the calcs are not per FM.  There are 5 things you pull from FM and 
only these 5 things, density, design area, hose stream allowance, duration and 
minimum k-factor.  And really these only apply to things defined as HC1-3.  For 
example HPS would follow NFPA 13.

Does FM allow the "small room rule" for end head pressures in small room
rules as in NFPA #13?

The UFC is confusing as the installation goes by 13 and the calcs go by FM
standards.....

Thanks,
