16- 219 C.M.R. ch. 4, § 2
2-1 Devices and Materials
2-1.1 Only listed new residential sprinklers shall be employed in the installation of life-safety sprinkler systems. Standard sprinklers or fast-response sprinklers of intermediate or high temperature rating may be installed in areas of high ambient temperature. Sprinklers shall be listed.
2-1.2 Only listed and approved materials and devices shall be used in sprinkler systems.
Exception: Listing may be waived for tanks, hangers, water flow detection devices and water control valves. All electrical components must be U.L. listed.
2-1.3 Pre-engineered systems shall be installed within the limitations which have been established by the testing laboratories where listed.
2-2 Acceptance Tests
2-2.1 The installer shall perform all required acceptance tests,, complete the Contractor's Material and Test Certificate(s), and forward the certificates to the "authority having jurisdiction", prior to asking for approval of the installation.
2-2.l.l When the "authority having jurisdiction" desires to be present during the conducting of acceptance tests, the installer shall give advance notification of the- time and date the testing will be performed.
2-2.2 Underground mains and lead-in connections to system risers shall be flushed before connection is made to sprinkler piping, in order to remove foreign materials that may have entered the underground piping during the course of the installation. For all systems, the flushing operation shall be continued until water is clear.
2-2.2.1 Underground mains and lead-in connections shall be flushed at the hydraulically calculated water demand rate of the system,
2-2.2.2 To avoid property damage, provision shall be made for the disposal of water issuing from test outlets.
2-2.3 All aboveground piping shall be hydrostatically tested at 200 p.s.i. for two hours, in accordance with N.F.P.A. #13, Standard for the Installation of Sprinkler Systems.
2-2.4 It is suggested, but not required, that all underground supply piping from the water utility shut-off to the sprinkler system connection be hydrostatically tested at 50 p.s.i. above the expected static pressure for two hours, to ensure the reliability of the materials and installation.

| HYDROSTATIC: Hydrostatic tests shall be mad at not less than 200 psi (18.6 bars) for two hours or 50 psi (3.4 bars) above static pressure in excess of 150 psi (1.07 bars) for two hours. Differential dry-pipe valve clappers shall be left open during test prevent damage. All aboveground piping leakage shall be stopped. FLUSHING: Flow the required rate until water clear as indicated by no collection of foreign material burlap bags at outlets such as hydrants and blow-offs. Flush at flows not less than 400 GPM (1514 L/min) for 4-inch pipe, 600 GPM ( 2271 L/min) for 5-inch pipe, 750 GPM (2833 L/min) for 6-inch pipe, 1000 GPM (3785 L/min) for 8-inch pipe, 1500 GPM (5678 L/min) for 10-inch pipe and 200 GPM (7570 L/min) for 12-inch pipe. When supply cannot produce stipulated flow rate obtain maximum available. PNEUMATIC: Establish 40 psi (2.7 bars) air pressure and measure drop which shall not exceed 1 % psi (0.1 bars) in 24 hours. Test pressure tanks at normal water level and air pressure and measure air pressure drop which shall not exceed 1% psi (0.1 bars) in 24 hours. | ||||
