Abstract : Three window assemblies, described herein, were tested in accordance with the standard procedures outlined in IMO Res. A.517(13) "Fire Test Procedures for A, B and F Class Divisions." The assemblies were exposed for a minimum 60-minute fire exposure without allowing excessive temperature rise or passage of flame. Since the integrity of the window assemblies were maintained during the entire exposure period, the assemblies each met the requirements for a class A-O window assembly. At the conclusion of the fire exposure period, each assembly was subjected to the hose stream test as outlined in ASTM E 119-83, "Standard Test Methods of Fire Tests of Building Construction and Materials." Each of the three assemblies met the requirements for the hose stream by maintaining their integrity and not forming through openings during the hose stream test. The primary purpose of performing these tests was to determine the radiative heat flux and temperature measurements on the surface of the bulkhead when subjected to fire conditions. Peak heat flux recorded from the unexposed surface of the assemblies was approximately 75 kW/ sq m with cumulative fluxes at 60 minutes of approximately 150 MJ/sq m. Indicated surface temperatures on the panes approached 800 deg C, while the steel framework showed surface temperatures of approximately 600 deg C. jg p3
