Burning Behaviour of Upholstered Chairs

(Part 2, Burning Rate of Chairs in Fire Tests)

抄録

This paper describes two series of fire tests of upholstered chairs for the investigation of their burning behaviour and for the comparison of results between the two series. The two series were (1) C-series, where the test specimen was located at the center of a test room, and (2) W-series, where it was located at the side of a wall. Measurements were made of the following items: mass burning rate, radiative heat transfer to the surroundings, heat transfer to the wall, optical smoke density, etc. In comparing the two series, no obvious difference between mass burning rate could be seen. For an engineering point of view it could be assumed that the burning rate of chair at the side of the wall is the same as at the center of the room. Also the radiant heat flux from flame can be expressed as a function of the mass burning rate and the distance from flame.
