Abstract:
Many fires occur in ambient atmospheric conditions. To
investigate certain types of firew, however, it is
necessary to consider combustion where the oxidizer is
not 21% oxygen/79% nitrogen. The Cone Calorimeter (ASTM
E 1354, ISO DIS 5660) has recently become the tool of
choice for studying the fire properties of products and
materials. Its standard use involves burning specimens
with room air being drawn in for combustion. To
facilitate studying fires involving different
atmospheres, a special version of the Cone Calorimeter
was designed. This unit allows controlled combustion
atmospheres to be created by the use of bottled or piped
gases. To make such operation feasible, a large number
of design details of the standard calorimeter had to be
modified. This paper describes the background for these
changes and provides an explanaiton of how the
controlled-atmospheres unit is operated.
