Pipe Test Pressure 1

[moiz19670309]

In designing a dry open sprinkler deluge system what would be the test pressure of the pipe used just before the open sprinkler. Does this dry pipe which is open to atmosphere requires a pressure test?. It is a ASTM A 53 pipe. Kindly inform.

NFPA 13-2010 24.2.1.1 Unless permitted by 24.2.1.2 through 24.2.1.8, 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.

24.2.1.12 When deluge systems are being hydrostatically tested, plugs shall be installed in fittings and replaced with open sprinklers after the test is completed, or the operating elements of automatic sprinklers shall be removed after the test is completed.
