Research on Fire Endurance of Tempered Glass based on Infrared Imaging Technology

Abstract

The tempered glass is widely used in the buildings because of its good transparence and fire endurance under the protection of the sprinkler.The fire backdraft may occur under the good ventilation condition after the tempered glasses fall apart in fire, which can endanger the human evacuation and fire rescue. By the testing of the surface temperature of the tempered glass exposed to the building fire, the critical temperature of the glass fracture can be acquired and the basis for the prediction and prevention of the fracture of the tempered glass then can be provided, which is useful for the performance-based design of the fire safety. The infrared imaging equipment is firstly used in China for the research on the fire endurance of the tempered glass.

Impact of solar radiation and environmental temperature on Art Nouveau glass windows

“…To map the natural heating of the different materials on stained-glass windows, it is necessary to use infrared (IR) thermography, a portable technique capable of measuring in situ the temperature on different areas and over time. This technique has been applied to evaluate the thermal efficiency of different windows systems [21,22], as well as, to evaluate glasses with different industrial purposes [23][24][25][26], to research fire endurance of tempered glass [27], to study the mechanical defects and the elastic deformations on glass sheets [28][29][30][31][32], and to analyze the efficiency of solar cells [33,34]. The application of IRthermography on historical glasses is scarce [20,32,33]; nevertheless, these studies proved to be a useful tool to evaluate the conservation of historical stained-glass windows [35,36].…”

Comparative assessment of stained‐glass windows materials by infrared thermography

“…Moreover, the high reflectance of glasses, mainly at incidence angles higher than 45 degrees, can produce erroneous temperature estimations. 36,37 Nevertheless, IR thermography has been applied successfully to evaluate windows for industrial purposes, [38][39][40][41] to research fire endurance of tempered glass, 42 to study the mechanical defects and the elastic deformations on glass sheets, [43][44][45][46][47] to analyze the efficiency of solar cells 37,48 and to detect damages on fiber optics. 49,50 Stained-glass windows are composed by glasses, which can be painted with enamels and grisailles, mounted on lead cames to form window panels.…”

Deterioration Mechanisms and Advanced Inspection Technologies of Aluminum Windows

“…These differences in turn help with the identification of defects. Due to its powerful functions, infrared (IR) thermography has been applied to evaluate mechanical defects and elastic deformations in glass sheets, as well as corrosion defect characterization [ 84 , 85 , 86 ].…”
