IN A REAL-WORLD FIRE TEST, ONLY FIRELITE SURVIVED THE HOSE STREAM TEST.
Results of research on fire-rated glass components under conditions approaching real-world fire accident
The National Research Institute of Fire and Disaster, The University of Tokyo, E.R.S. and Nippon Electric Glass Co., Ltd.conducted joint research on the behavior of fire-rated glass.
Through observation and measurement, they gathered data under heating conditions approaching those of a real-world fire while monitoring for damage and the reaction when the glass sheets were exposed to a water stream from a fire-fighting hose.
- Heat Resistant Glass Ceramics t5.0㎜/ FireLite
- Heat Resistant Tempered Glass t8.0㎜
- Test Method
- A 1.22 meter x 1.93 meter panel of fire-rated glass mounted in a frame was installed in a test room measuring 4 m x 4 m x 2.3 m high. The test also used a doubled-up block of No. 2 crib as a test fire source that maintained a room temperature of 700℃ for about 15 minutes. When the side of the glass not exposed to the fire reached the point of maximum temperature (about 470℃), it was impacted with a water-filled ball made of polyethylene film (with a water volume of 300 cc to 930 cc）.
- Test Result
- FireLite showed no change at all from the impact of the water ball under the simulated real-world fire accident conditions. On the other hand, the tempered heat-resistant glass shattered into pieces from the temperature shock created by the impact of the water ball, causing the fire to flare up considerably.
