Preliminary Tests
**************************************************************************
NOTE: Specify hydrostatic test not less than 1379
kPa or 345 kPa 200 psi or 50 psi above the maximum
working pressure when the maximum working pressure
is greater than 1034 kPa 150 psi.
**************************************************************************
Each piping system shall be hydrostatically tested at [1379 kPa (gage)]
[200 psig] [_____] in accordance with NFPA 11 and NFPA 13 and shall show no
leakage or reduction in gage pressure after 2 hours. The Contractor shall
conduct complete preliminary tests, which shall encompass all aspects of
system operation. Individually test all detectors, manual actuation
