    (1) Imperial Tobacco Canada Ltd, Montréal, QC, Canada; (2) British American Tobacco, Group R&D, Southampton, U.K.
    Before the introduction of the Canadian Tobacco Reporting Regulations (TRR), the Regulator stated a need to obtain more information on tobacco product emissions to support, amongst other things, “better program design” and the “right to know”. The...

    (1) delfortgroup AG, Traun, Austria; (2) British American Tobacco, Group R&D, Southampton, UK; (3) Consultant to delfortgroup AG, Traun, Austria
    To check the compliance of cigarettes with low ignition propensity regulations, it is necessary to estimate the rate of self-extinguishment a cigarette will have, when tested according to ISO 12863. One way to do this is to actually perform the test...
