5.18 Lateral Discharge Test (see 4.18 ) [7.19]

 Water should be discharged from a spray nozzle at the minimum operating and rated working pressure. A second automatic nozzle located at the minimum distance specified by the manufacturer should be mounted on a pipe parallel to the pipe discharging water.

 The nozzle orifices or distribution plates (if used), should be placed 550 mm, 356 mm and 152 mm below a flat smooth ceiling for three separate tests, respectively at each test pressure. The top of a square pan measuring 305 mm square and 102 mm deep should be positioned 152 mm below the heat responsive element for each test. The pan should be filled with 0.47l of heptane. After ignition, the automatic nozzle should operate before the heptane is consumed.
