120-3-3-.04(121)(a)(1) indicates NFPA 291 (2002) provides recommendations for flow testing. Due to the importance of accurately predicting the water supply available for fire protection, pressure gauges used for the waterflow test necessitate having their calibration tested within the last twelve months in accordance with NFPA 291 (1998), Section 4.4.2, and the test should be witnessed by the Local Fire Official or Water Department. Submit a copy of calibration tests indicating test gauges comply with ASME standards and therefore the waterflow test complies with this section. The waterflow test date must comply with 120-3-3.04(6)(e), Part 1, modifications to NFPA 13 (2002), which added Section 15.2.1.3, requires water flow test to be performed within six months of plan submittal, and the test was duly witnessed by the local Fire Department per 2003 IFC, Section 508.4. Finally, the Hydraulic Calculations must comply with 120-3-3.04(6)(d), Part 2, modifications to NFPA 13 (2002), which added Section 14.4.4.8.3, requiring a minimum 10 psi cushion safety factor.
