to a silver-brazing bronze reducing tee in accordance with MIL-F-1183. Normal
installation practice using teflon tape applied to sprinkler head threads shall be
used and the sprinkler tightened using the manufacturer's specified torque. Tests
shall be performed with the sprinkler head unpressurized and pressurized to 175
psig. Momentary leakage during shock is acceptable. Loosening of parts, material
failure or deformation that causes maloperation shall be cause for rejection.

or horizontal as required. Tests shall be performed unpressurized and pressurized
to 175 psig. Leakage or weeping during tests, material failure, loosening or
deformation of parts shall be cause for rejection. After completion of test, the
