In our NZ Standard NZS541 a sprinkler with RTI between >50 and <80 is designated a "Special Response Sprinkler". These usually have a 4mm bulb. "Std Response" has a 5mm or larger bulb and the "Fast Response" has a 3mm bulb.

I am really more interested in the reasoning for the DEFINITION in NFPA #13, not some box of heads in RTI limbo. Any TC members out there not totally fed-up with me yet? _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum
