Abstract

Five large-scale rack-storage fire tests and supplemental Actual-Delivered-Density (ADD) measurements were conducted to determine whether a K-16.8, quick-response, upright sprinkler could provide fire suppression performance under horizontal ceilings 9.1m and 10.7m high. The designated sprinkler operating pressures were 241 and 345 kPa, respectively. The sprinkler spacing used in this evaluation was 3.1 [micro] 3.1 m. The fire hazard targeted under the 9.1-m high ceiling was up to that represented by rack-storage, expanded Group A plastics in cartons, and the fire challenge under the 10.7-m high ceiling was up to that of unexpanded Group A plastics in cartons, also stored in steel racks. In these tests, the prototype sprinkler demonstrated fire protection performance expected from a suppression-mode sprinkler within its intended applications. One of the tests conducted under the 9.1-m high ceiling showed that the sprinkler's performance was little affected by the presence of a building bar joist obstruction investigated in this program.
