GENERAL TEST PROCEDURES
Class I Dry and Class III (Continued) (h) On-site Water Supply: [1] Determine that filling for on-site water supply, if provided, operates when flow test is conducted. [2] Determine that air pressure and/or water supply gauges, if provided, are in proper working condition. (i)
Hose: Disconnect hose, from Fire Department outlet (if provided). Examine full length of hose section for mildew, cuts, abrasions, and other deterioration. Check hose couplings, gaskets, and nozzle for damage and obstruction. Hydrostatic testing of fire hose shall be conducted in accordance with NFPA 1962, Chapter 5. and title19/NFPA 25 California edition
(2)
Class II (Wet) Standpipes: (a) Flow Test: Determine that the system and its water supply will meet one of the following standards according to the date of its installation. Test gauges shall be used to measure residual pressures and an approved flow meter shall be used to measure water flow quantities. The required water flow must be maintained for at least thirty seconds from systems supplied by street mains or gravity tanks and at least two minutes from systems supplied by booster pumps or pressure tanks: (b) The following Class II and Class H systems shall have a minimal residual pressure and flow at the topmost outlet of each riser:
NOTE: 1-1/2� Hose stations connected to automatic sprinkler systems installed under NFPA 13 are not required to meet flow requirements of NFPA 14 or Title 19/NFPA 25 California Edition. [1] [2] [3] [4]
