Joint research by the University of Tokyo, Engineering & Risk Services Corporation, and NEG
- (1) Heat-resistant tempered glass(8 mm thick)
- he glass broke during the heating process (4 min. 15 sec. after the start of heating) before it was impacted by a water-filled ball.
- (2) Heat-resistant tempered glass(8 mm thick)
- The glass broke during the heating process (8 min. 21 sec. after the start of heating) before it was impacted by a water-filled ball.
- (3) FireLite
- FireLite showed no change at all when heated and impacted by a water-filled ball.
Test method
The glass temperature on the other side of the heat source was increased to 500°C or higher. A temperature gradient was created in the height direction of the specimen.
The glass surface on the other side of the heat source was impacted by a certain amount of water, and was checked for changes including breakage.
