Funny that this is an active thread again. Just got a spec' for an Army Housing project. They call for a design in accordance with NFPA 13R, and rack sprinklers per NFPA 230 with a maximum velocity of 20 FPS. The real question here is where can I find out the country of origin of the dope the EOR is smoking so that I can at least try to get on the same page as the design team?
