    Using residual length data to estimate the rate of self-extinguishment of banded cigarettes

    EITZINGER B.(1); RIVAS CANO A.(2)
    (1) delfortgroup AG, Traun, Austria; (2) JT International Germany GmbH, Trier, Germany
    For non-banded lower ignition propensity (LIP) cigarettes the residual length of extinguished cigarettes has been shown to be useful to more precisely estimate the rate of self-extinguishment compared to just counting self-extinguished cigarettes (ISO ...

    (1) Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria; (2) delfortgroup AG, Traun, Austria
    In the tobacco industry it is well known that porosity is one of the most significant physical properties of cigarette paper. There are indirect as well as direct methods to characterise this parameter. Measurement of the diffusion capacity and the air ...
  3. CORESTA Congress, Quebec, 2014, Smoke Science/Product Technology Groups, ST 95

    The pore size distribution of naturally porous cigarette papers and its relation to air permeability and diffusion capacity – Part 2

    EITZINGER B.(1); GLEINSER M.(2); BACHMANN S.(2); VOLGGER D.(2)
    (1) delfortgroup AG, Traun, Austria; (2) Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Several publications have shown in the past, on theoretical grounds and by actual measurements, that the perforation of cigarette papers causes a substantial increase in air permeability, while the diffusion capacity increases comparably less. These ...

    The pore size distribution of naturally porous cigarette papers and its relation to air permeability and diffusion capacity – Part 2

    EITZINGER B.; GLEINSER M.; BACHMANN S.; VOLGGER D.
    delfortgroup AG, Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Regulations regarding the self-extinguishment of cigarettes and the upper limits on smoke yields have, in addition to air permeability, led to an appreciation of diffusion capacity as a further important parameter of cigarette paper. Air permeability and ...
  6. CORESTA Congress, Sapporo, 2012, Smoke Science/Product Technology Groups, PT 15

    Comparison of two maximum-likelihood estimators of the rate of self-extinguishment in the ISO 12863 test

    EITZINGER B.(1); COBURN S.(2); CASE P.(3)
    (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 ...
