WebNov 17, 2016 · To determine this low temperature, one inputs the assumed flash point temperature and the shutter time (auto and ramp mode is also provided). The sample chamber/cup is first heated to the input flash point temperature. Then the sample liquid is added into the chamber. When the time is reached, the flame is placed closer to the … WebWhat is arc flash? Arc flash is the light and heat created from an arc fault explosion. Temperatures of an arc flash can reach as much as 2,800 to 19,000 °C (5,000 to 35,000 °F). To give you some perspective; the temperature of the surface of the sun is estimated at 5,500 °C (9,932 °F).
