Inthe smoke chamber test, a key problem is to accurately measure the transmissivity of the smoke.In this paper, the relationship between the temperatures measured and the radiation received bythe thermal imager has been disussed. The equation to accurately calculate the infraredtransmissivity of the smoke from the measured temperature is deduced. This equation is alsocompared with the simplified one. ER -
