    Many regulations worldwide require the reporting of tar, nicotine and carbon monoxide (TNCO) and set limits on their yields measured following the ISO smoking regime (ISO3308, 2012). The intention of FCTC Art. 9 is to characterise and monitor cigarettes, ...

    Prediction of smoke exposure from smoking time

    CAHOURS X.(1); COLARD S.(2); VERRON T.(1); JULIEN R.(1); PURKIS S.W.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, U.K.
    We have recently shown that cigarette smoke yield (TNCO) depends linearly on the difference between the time of smouldering and the time of smoking using several machine smoking regimes (CORESTA 2012), with the filter ventilation open or blocked. It is ...

    Factors driving short term smoking compensation

    CAHOURS X.(1); PURKIS S.W.(2); VARIGNON B.(1)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, U.K.
    Smoking compensation, defined as a modification of smoking behaviour, i.e. increase in puffing intensity, has been studied extensively. It has often been stated that compensation, generally occurs following a switch to a lower tar and nicotine yielding ...

    Cigarette burning and alternative smoking regime

    COLARD S.(1); VERRON T. (2); PURKIS S.W.(1); CAHOURS X.(2)
    (1) Imperial Tobacco Limited, Bristol, UK; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    Context and objective: Some regulations require the use of two smoking regimes. The objective of this study is to better understand the impact of the smoking regime on the cigarette burning process. The combustion of a cigarette during smoking can be ...

    Statistical simulation to evaluate the effects of the number of laboratories and replicates on the precision of measurement method

    VERRON T.(1); CAHOURS X.(1); PURKIS S.W.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    In an inter-laboratory comparison, different laboratories measure particular characteristics of a product. For cigarettes, smoke analyte yields in one or more homogeneous samples are measured under ISO-defined conditions. The comparison of different ...
