    Control or monitoring of the LIP testing process: The fitness for purpose of the LIP standard products

    WILKINSON P.(1); COLARD S.(1); VERRON T.(2); CAHOURS X.(2); PRITCHARD J.(1)
    (1) Imperial Tobacco Limited, Bristol, U.K.; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    Lower Ignition Propensity (LIP) is a product safety standard intended to increase the probability that a cigarette will self-extinguish under strictly controlled laboratory conditions. LIP compliance indicates that the probability that a cigarette...

    LIP cigarettes: Proposal for an alternative sampling design

    VERRON T.(1); CAHOURS X.(1); COLARD S.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, U.K.
    Low ignition propensity cigarettes are intended to increase the chances of self-extinguishment under laboratory conditions following the protocol detailed in either ISO 12863:2010 test method or ASTM E2187-09. The safety requirements state that a...

    Analytical method to model human mouth-level transfer of ingredients from Swedish pouched snus

    GRAPTON S. (1); GADOIS-POMMEREUL S.(1); TROUDE V.(1); BLANCHET M. (1); CLARKE A.(2); SIMMS L.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, U.K.
    In parallel with the human study[1] a laboratory in vitro assay was conducted with three media: artificial saliva, water and 1% ß-cyclodextrin in water, using two snus products that were indistinguishable apart from the flavour application rate. To...

    Tobacco reference materials: uses and limitations

    TEILLET B.(1); CAHOURS X.(1); COLARD S.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, U.K.
    In the framework of the growing regulations of tobacco products, interest is expressed in wider characterisation in terms of contents and emissions. This leads to the need for analytical methods providing accurate, reliable and consistent data. This...

    Cigarette Reference Material: Regulatory requirements, manufacture, and validation of CORESTA Monitor CM7 test pieces

    MÜLLER C.(1); VERRON T.(2); HUEHNE T.(1); PETERS G.(1)
    (1) Imperial Tobacco Group, Reemtsma Cigarettenfabriken GmbH, Hamburg, Germany; (2) SEITA, Imperial Tobacco Group, 48 rue Danton, 45404 Fleury-les-Aubrais, France
    International standards (e.g. ISO 16055) describe the use of monitor test pieces for monitoring the stability of the analytical processes involved when using a cigarette-smoking machine for routine analyses. In particular, monitor test pieces are...

    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...

    Some key points to assess LIP regulations

    VERRON T.(1); CAHOURS X.(1); COLARD S.(2); TASCHNER P.(3)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, U.K.; (3) Imperial Tobacco Group, Reemtsma Cigarettenfabriken GmbH, Hamburg, Germany
    Lower ignition propensity (LIP) cigarettes are designed to extinguish more quickly than conventional cigarettes with the intention not to cause accidental fires when left unattended. LIP regulations have so far been introduced in several countries....

    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, UK
    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 (TSRC 2012), with the filter ventilation open or blocked. It is...

    Do cigarette smoke yields from a single smoking regime fit with current regulatory objectives?

    COLARD S.(1); VERRON T.(2); JULIEN R.(2); CAHOURS X.(2); PURKIS S.W.(1)
    (1) Imperial Tobacco Limited, Bristol, UK; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    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...

    Limitation of standard deviation to express variability.

    TEILLET B.(1); VERRON T.(1); CAHOURS X.(1); COLARD S.(2); PURKIS S.(2)
    (1) SEITA Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    In the framework of growing regulations regarding tobacco products, increased requirements are observed for reporting of analytical figures (e.g. FDA). This paper deals with the reporting of data variability in this context. The objective was to...
