| Abstract: | In the normal case, as we all know, when there is a fire, smoke will arise along with the fire. The height of the smoke layer interface is an important parameter to assess a fire hazard. A smoke generator was used in a hot smoke test. The test verified the feasibility of two methods of measuring the smoke layer interface: ocular estimate and thermocouple measurement. The findings show that the ocular estimate is less accurate because subjective factors of the observer lead to changes of the data while the thermocouple measurement is more accurate. It has a delay in measurement, so revision of the delay should be taken into account and the two methods can be complementary. |
