Contractor's Material and Test Certificate for Underground Piping PROCEDURE Upon completion of work, inspection and tests shall be made by the contractor's representative and witnessed by an owner's representative. All defects shall be corrected and system left in service before contractor's personnel finally leave the job. A certificate shall be filled out and signed by both representatives. Copies shall be prepared for approving authorities, owners, and contractor. It is understood the owner's representative's signature in no way prejudices any claim against contractor for faulty material, poor workmanship, or failure to comply with approving authority's requirements or local ordinances.

Flush at flows not less than 390 gpm (1476 Llmin) for 44n, pipe, 880 gpm (3331 L/min) for 6-in, pipe, 1560 gpm (5905 Llmin) for 84n, pipe, 2440 gpm (9235 11mm) for 10-in, pipe, and 3520 gpm (13,323 1/mm) for 12-In, pipe. When supply cannot produce stipulated flow rates, obtain maximum available. Hydrostatic: Hydrostatic tests shall be made at not less than 200 psi (13.8 bar) for 2 hours or 50 psi (3.4 bar) above Test static pressure In excess of 150 psi (10.3 bar) for 2 hours. description Leakage: New pipe laid with rubber gasketed joints shall, if the workmanship is satisfactory, have little or no leakage at the joints. The amount of leakage at the joints shall not exceed 2 quarts per hour (1.89 Lihr) per 100 joints irrespective of pipe diameter. The leakage shall be distributed over all joints. If such leakage occurs at a few joints, the Installation shall be considered unsatisfactory and necessary repairs made. The amount of allowable leakage specified above can be Increased by 1 fluid ounce per inch valve diameter per hr. (30 mL/25 mm/hr) for each metal seated valve Isolating the test section. If dry barrel hydrants are tested with the main valve open so the hydrants are under pressure, an additional 5 ounces per minute (150 mI/mm) leakage Is permitted for each hydrant Nw upe round piping flushed according to Yes El No iv F'r' standard by (company) If no, explain Ho) flushing flow was obtained Through what type opening Flushing Public water El Tank or reservoir 0 Fire pump El Hydrant butt Open pipe tests Lead-Ins flushed according to A/fft standard by (company) 7jp , Yes El No If no, explain ci lv flushing flow was obtained Public water El Tank or reservoir El Fire pump Through what type opening Ky connection to flange El Open pipe and spigot 1999 Edition 13-150 INSTALLATION OF SPRINKLER SYSTEMS Figure 10-1(b) (Continued) Hydrostatic All new underground piping hydrostatically tested at Joints Covered test aso psi for __________ hours Yes No Total amount of leakage measured Leakage gallons hours Allowable leakage test gallons hours Number installed I Type and make I All Operate satisfactorily Hydrants c:1.

Fire service mains (from the water supply to the system riser) and lead-in connections to system ris- ers shall be completely flushed before connection is made to sprinkler piping. The flushing operation shall be continued for a sufficient time to ensure thorough clvaning. The minimum rate of flow shall be not less than one of the following The hydraulically calculated water demand rate of the system including any hose requirements That flow necessary to provide a velocity of 10 ft/sec (3.1 m/sec) (see Table 10-2.1(2)) The maximum flow rate available to the system under fire conditions 10-2.2 Hydrostatic Tests. 10-2.2.1 All piping and attached appurtenances subjected to system working pressure shall be hydrostatically tested at 200 psi (13.8 bar) and shall maintain that pressure without loss for 2 hours. Loss shall be determined by a drop in gauge pressure or visual leakage. The test pressure shall be read from a gauge located at the low elevation point of the system or portion being tested. Exception No. 1: Portions of systems normally subjected to system working pressures in excess of 150 psi (10.4 bar) shall be tested as de- 1999 Edition scribed in 10-2.2.1 at atiressure of 50 psi (3.5 bar) in excess of system working pressure. Exception No. 2: Where cold weather will not permit testing with wa- ter, an interim air test shall be permitted to be conducted as described in 10-2.3. Exception No. 3. Modifications affecting 20 or fewer sprinklers shall not require testing in excess of system working pressure. Exception No. 4. Where addition or modification is made to an exist- ing system affecting more than 20 sprinklers, the new portion shall be isolated and tested at not less than 200 psi (13.8 bar) for 2 hours. Exception No. 5. Mod4fications that canizotbe isolated; such as relocated drops, shall not require testing in excess ofsystem working pressure. Exception No. 6: In buried pipe, leakage shall be permitted as follows: (a)C The amount of leakage at the joints shall not exceed 2 qt/hr (1.89 L/hr) per 100 gaskets or joints, irrespective ofpipe diameter (b)* The amount of allowable leakage speczfied in item (a) of this exception shall be permitted to be increased by 1 fluid ounce (30 ml) per inch valve diameter per hour for each metal seated valve isolating the test section. (c). If dry barrel hydrants are tested with the main valve open so the hydrants are under pressure, an additional 5 oz/min (150 ml/ mm) of leakage shall be permitted for each hydrant. (d) The amount of leakage in buried piping shall be measured at the specified test pressure by pum ingfrom a calibrated container
