A test program was conducted to evaluate whether hose ports in fire doors compromise the fire integrity of the doors. Four fire doors were built according to Coast Guard construction requirements and were insulated for a Class A-15 fire rating. The doors were tested in accordance with the ASTM E152 Standard Methods for Fire Tests of Door Assemblies . The testing was carried out by Underwriters Laboratories in Chicago, Illinois under the direction of the United States Coast Guard. Two fire tests were conducted. Each test contained two Class A-15 fire doors installed in Class A-60 bulkheads. Each fire door assembly consisted of a frame, sill, hinges,a latch, a door and a hose port. Three of the doors contained a hose port. The fourth door did not have a hose port and was used as a baseline for comparison. Two single hinge hose ports and one double hinge hose port were used in the testing. Each fire door assembly was installed in a steel bulkhead to insure a test setup similar to normal shipboard installation. After the one hour fire test, the test panel was immediately removed from the furnace and the door assemblies subjected to the hose stream test specified in ASTM E152. Results show: 1) hose ports do not noticeably degrade the structural fire protection of a fire door, (2) fire doors built to Coast Guard construction requirements failed the performance requirements for the ASTM E152 fire test and (3) in the ASTM E152 test, a door positioned to swing into the furnace is a more severe test setup than a door positioned to swing away from the furnace.
