A. 9.2.1.3.3 Examples of areas of use include clean rooms, suspended ceilings, and exhaust ducts. 9.2.1.3.3.1 Listed flexible sprinkler hose fittings and its anchoring components, intended for use in installations connecting the sprinkler piping to sprinklers, shall be installed in accordance with the requirements of the listing including any installation instructions. 9.2.1.3.3.2 When installed and supported by suspended ceilings, the ceiling shall meet ASTM C-635 and shall be installed in accordance with ASTM C-636. 9.2.1.3.3.3*When flexible sprinkler hose fittings exceed 6 ft in length and are supported by a suspended ceiling a hanger(s) attached to the structure shall be required to ensure that the maximum unsupported length does not exceed 6 ft. A. 9.2.1.3.3.3 The committee evaluation of flexible sprinkler hose fittings supported by suspended ceilings was based upon a comparison of the weight of a 6 ft, 1 in diameter sch 40 water-filled flexible hose fitting weighing approximately 9 lbs. The information provided to the committee showed that the maximum load shed to the suspended ceiling by the flexible hose fitting was approximately 6 lbs and that a suspended ceiling meeting ASTM C-635, Standard Specification for the Manufacture, Performance, and Testing of Metal Suspension of Acoustical Tile and Lay-In Panel Ceilings,and installed in accordance with ASTM C-636, Standard Practice for Installation of Metal Ceiling Suspension Systems for Acoustical Tile and Lay-In Panels, can substantially support the load. In addition, the supporting material showed that the flexible hose connection can be attached to the suspended ceilings because it allows the necessary deflections under seismic conditions. NFPA 13 Code Language and Seismic Qualification 1228FH_Sub_030212npa_Layout 1 8/27/13 10:08 AM Page 3 •More than 90% of the states in the U.S. are adopting the International Building Code (IBC) that address, among other things, the installation of fire sprinkler systems in seismic zones. •The latest version of the IBC defers to ASCE 7 for the sprinkler/ceiling design in Seismic Design Categories (SDC) C and D, E & F. •In Seismic Design Category C, suspended ceilings are to be designed and installed in accordance with Ceilings & Interior Systems Construction Association (CISCA) recommendations for Zones 0-2; and sprinkler heads and other penetrations shall have a minimum of 1/4-inch clearance on all sides. •In Seismic Design Categories D, E & F, suspended ceilings are to be designed and installed in accordance with CISCA recommendations for seismic Zones 3 and 4 with some additional requirements. Except where rigid braces are used to limit lateral deflections, sprinkler heads and other penetrations shall have a 2-inch oversized ring, sleeve, or adapter through the ceiling to allow for free movement of at least 1 inch of ceiling movement in all horizontal directions. •Flexible sprinkler connection provide characteristics that exceed the most stringent seismic code requirements. The flexibility of the hose allows the head to move with the ceiling in any direction during a seismic event without causing damage to the sprinkler system. •FlexHead Industries recently satisfactorily completed full-scale seismic qualification testing at the Structural engineering Earthquake Simulation Laboratory located at the State University of New York at Buffalo using the International Code Council (ICC) testing standard “ICC AC-156 Seismic Qualification Testing of Nonstructural Components”. 4 FlexHead®Satisfies New Seismic Code Requirements Mounting bracket Reducing fitting Sprinkler head Ceiling tile Suspended t-bar grid Sprinkler branchline Pipe nipple Flexible connecting hose in standard lengths — allows the head to move in any direction during a seismic event without causing damage to the sprinkler system FlexHead Industries recently satisfactorily completed full-scale seismic qualification testing at the Structural Engineering Earthquake Simulation Laboratory located at the State University of New York at Buffalo. Tests were conducted using the International Code Council (ICC) acceptance criteria “ICC-ES AC-156 Seismic Qualification Testing of Nonstructural Components”. This is the first time a sprinkler component has been seismically certified using test criteria accepted by the ICC. Typically, each unit consists of a threaded pipe nipple for connecting to the main or branch feeder line, a flexible hose in standard lengths, a reducing fitting that the sprinkler head attaches to, and a mounting bracket. 1228FH_Sub_030212npa_Layout 1 9/12/13 3:15 PM Page 4 www.flexhead.com FlexHead Model # Internal I.D. in Outlet Orifice Size in (cm) Hose Assembly Length ft (cm) Maximum Number of 90-degree Bends Maximum Equivalent Length of Schedule 40, Nominal 1in.

The assembly showed no signs of rupture, cracking, permanent distortion, or deterioration of performance characteristics. The FlexHead successfully passed this test. Vibration Test A sample FlexHead was secured to a vibration table. The FlexHead hose was bent in a 90° angle and pressurized to 90 psi (620 kpa) and the mounting bracket and hose were then subjected to a total of 25 hours of severe vibration conditions. After the successful completion of the vibration tests the sample was subjected to the hydrostatic pressure test at 700 psi and showed no signs of deteriora tion. The FlexHead successfully passed this test. Friction Loss (Equivalent length of pipe) To determine the effect of the FlexHead to the discharge coefficient of the sprinkler, the average friction loss through the FlexHead shall be equated to the theoretical length of nominal 1” diameter schedule 40 sprinkler pipe which would produce the same amount of friction loss. Please see friction loss table. Vacuum Test A sample FlexHead was subjected to a vacuum of 25 inHG for a period of five minutes. After the success ful completion of the Vacuum Test the sample was subjected to the hydrostatic pressure test at 700 psi and showed no signs of deterioration.

The sample length is then to be measured again and the length shall not change by more than 0.1 inch/foot of hose length. Mechanical Strength Test A flexible sprinkler hose with fittings installed in its intended position using the anchoring components referenced in the installation instructions shall withstand a torque of 60 pound-feet (81 Nm) applied to the outlet without movement of the fitting outlet, deformation, or fracture. High Temperature Exposure Test Two samples are to be prepared and subjected to a hydrostatic pressure of twice the rated working pressure. The samples are then to be allowed to dry and then exposed to an ambient temperature in accordance with Table 10.1 for 90 days. Following this exposure, the samples are to be individually subjected to a hydrostatic pressure of twice the rated working pressure for 1 minute. Vibration Test Samples are to be vibrated for a period of 30 hours at frequencies ranging from 18 to 37 Hz. During and after being subjected to the required vibration, the samples are to be examined for signs of leakage, rupture, or movement of the outlet fitting affecting the performance of the flexible hose assembly. Equivalent Length Determination A sample of each length shall be tested in straight lengths and with the maximum number of minimum radii bends referenced in the installation instructions. The calculated pressure loss from the piezometers, corrected for the inlet and outlet velocities, are to be subtracted from the test sample results to obtain a pressure drop for the fitting. Using the Hazen-Williams coefficient of friction of 120, the equivalent length, in feet (m) of pipe, is to be calculated. Salt Spray Corrosion Test Ferrous flexible sprinkler hose with fittings and ferrous anchoring components not protected with a coating shall withstand an exposure to a salt spray atmosphere for 10 days without exhibiting any incipient corrosion. Stress-Corrosion Cracking of Stainless Steel Parts Test Austenitic stainless steel parts shall show no evidence of cracking, delamination, or degradation after being subjected to boiling magnesium chloride solution. The exposure is to last for 150 hours. The test samples are to be examined using a microscope having a magnification of 25X for any cracking, delamination, or other degradation as a result of the test exposure. Low Temperature Test for Dry Pipe Systems Each sample is to be gradually pressurized with air to a pressure of 40 psig (276 kPa) and then sealed. The pressurized assembly is then to be placed horizontally in air maintained at a temperature of minus 40°F (minus 40°C) for a period of 24 hours. Following the 24 hour low temperature exposure, the assembly is to be place in room ambient temperature of 73 ±5°F (23 ±3°C) for an additional 24 hour period. There shall be no decrease in the pressure in the assembly from the pressure measured before the low temperature exposure. Pressure Cycling Test The samples are to be connected to a pressure cycling apparatus, filled with water and vented of all air. The internal pressure is to be cycled 3,000 times from 0 psig (0 kPa) to twice the rated working pressure to 0 psig (0 kPA) at an approximate rate of 10 cycles per minute. During the pressure cycling, observations are to be made for evidence of leakage or physical damage. Vacuum Test Flexible sprinkler hose with fittings shall withstand a vacuum of minus 8.84 psi (minus 61 kPa) without collapse, leakage, or other deterioration of the flexible sprinkler hose and fitting performance characteristics. High Pressure Flow Test Flexible sprinkler hose with fittings and its anchoring components shall maintain the attached sprinkler in the intended operating position while the sprinkler discharges water at 90 percent of the rated pressure of the flexible sprinkler hose. Fatigue Test (Limited Flexibility) Flexible hose with fittings shall withstand without leakage or damage repeated flexing in a direction parallel to the axis of the end fittings. The number of flexing cycles shall be 100 cycles.
