It appears there's a conflict in understanding, as section 10.6.1.1.6 outlines a requirement for a flow rate of 1,250 gallons per minute (gpm) for buildings lacking sprinkler coverage, in line with NFPA 13 standards. Yet, 10.6.1.1.6 omits any mention of NFPA 13R, leading to confusion about the necessity of meeting the 1,250 gpm requirement in scenarios where NFPA 13 standards might not be mandated by the building code but NFPA 13R. Furthermore, NFPA 14 does not discuss provisions for buildings with partial sprinkler protection according to NFPA 13R.
