Section 703-1-5.0 - Acceptance Tests

5.1.1 All standpipe systems and equipment, including fire pumps, shall be tested and approved before the system is placed into service.

5.1.2 All standpipe systems shall be tested hydrostatically to demonstrate that the system will sustain for two (2) hours a pressure of not less than 200 psi (1379 kPa) or 50 psi (345 kPa) in excess of the maximum normal pressure when the maximum normal pressure is in excess of 150 psi (1034 kPa).

5.1.3 Wet and dry pipe systems shall be tested to determine that the source of water supply is adequate to maintain a minimum flow and pressure at the topmost hose outlet as required for the system design by the applicable codes and standards listed in Regulation 701.

5.1.4 A working test of dry pipe valves, quick opening devices and air maintenance devices, if installed, shall be made before acceptance. Dry pipe systems must deliver water at the most remote hose outlet in not more than 60 seconds, starting at the normal operating air pressure.

5.1.5 Standpipe fire lines without permanent or automatic water supply and equipped with a fire department connection shall be capable of delivering 250 gallons per minute simultaneously from each of any three outlets under the operation of one fire engine or pumper.

5.2.1 All suppression systems shall be tested in accordance with the applicable codes and standards as listed in Regulation 701, prior to being placed in service.

5.3.1 Fire pumps shall be tested in accordance with the Standard for the Installation of Centrifugal Fire Pumps, NFPA 20, as adopted and/or modified by these Regulations and shall demonstrate the suitability of the pump for its intended use.

5.3.2 The pressure in public mains shall not be reduced below 10 psi while the pump is operating at 150 percent of its rated capacity or at peak capacity, whichever is less.

5.4.1 The complete system, including automatic fuel shutoff valves and switches, shall be tested by Companies or individuals licensed under the provisions of these Regulations as required by the State Fire Marshal. These tests shall be adequate to determine that the system has been properly installed and will function as intended. A cooking appliance shall not be placed into service or reactivated until a final inspection is made and acceptance approval is given by the State Fire Marshal.

5.4.2 A Certificate of Installation shall be forwarded to the State Fire Marshal by the installer of a new system. Certificates of Installation shall be submitted in such form as the State Fire Marshal may prescribe. The Installer shall certify in writing that the installation has been made in accordance with the approved plans and that all component parts of the system are in service. Acceptance approval by the State Fire Marshal shall be withheld until said Certificate of Installation is received and accepted by the State Fire Marshal.
