Standard Time-Temperature Curve 1
Standard Time-Temperature Curve 1 :
The plot of time vs. temperature representing the maximum severity of a fire completely burning out a brick, woodjoisted building and its contents; it is detailed in ASTM E 119 and is a convenient measure for general fire testing. However, it actually represents the high severity of the early stages of actual fires in which combustible materials are prone to rapid development of high temperatures. Its determining points are: 1000°F at 5 minutes; 1300°F at 10 minutes; 1550°F at 30 minutes; 1700°F at 1 hour; 1850°F at 2 hours; 2000°F at 4 hours; and 2300°F at 8 hours.
