21、gstosilicic acid IntroductionCigarettes are manufactured to close tolerances using strict quality control procedures.However, the main constituents involved in the manufacture are derived from natural products (such as tobacco and paper) and this results in a final product which is intrinsically var
22、iable. Further complexity arises as the cigarette is converted to cigarette smoke during smoking.The quantitative measurement of nicotine, of particulate matter and of nicotine-free dry particulate matter (NFDPM, sometimes referred to as “tar”) is therefore dependent on the arbitrary definition of t
23、he means used to generate and collect the smoke. In particular, the ambient conditions (e.g. temperature, humidity, air movement within the laboratory) under which the test pieces are conditioned and smoke is collected play a critical role in the accuracy of the measurement.Sidestream smoke in this
24、International Standard is understood to be the smoke that is evolved from the cigarette during the smoking run other than from the mouth end (which is called mainstream smoke).NOTE Sidestream smoke is distinguished from environmental tobacco smoke (ETS), which is a mixture of aged and diluted exhale
25、d mainstream smoke and aged and diluted sidestream smoke, and for the assessment of which the present method does not apply.From the time that scientists first attempted to determine nicotine and total and dry particulate matter yields in sidestream smoke, many different methods have been adopted. H
26、owever, experience has shown some procedures to be more reliable and more amenable to handling of large numbers of samples. With these factors in mind, during the 19992002 period, collaborative studies by a task force composed of CORESTA (www.coresta.org) members have shown that improvements in repe
27、atability and reproducibility result when some restrictions are placed upon the wide variety of methods and practices described in existing methods.This International Standard, produced after much collaborative experimentation by many laboratories in many countries, reflects the results of the optim
28、ization proposed and validated by the task force and provides one set of procedures that are the accepted reference procedures and for which repeatability and reproducibility of the determinations were assessed. Experience in the task force has shown how strict adherence to the detailed set up and c
29、onditions of the method, as well as the degree of proficiency of the operator, affect the precision of the results.Further, it is preferable that the selected method be compatible with different modes of cigarette equilibration or puffing parameters for the smoking of the tested pieces. The ISO stan
30、dards for the determination of mainstream smoke yields were, however, followed to the largest possible extent, although the machines used by the different laboratories were all of a linear type.This method is a machine method and it allows cigarettes to be smoked using a strictly controlled set of p
31、arameters. Thus it enables the sidestream smoke NFDPM and nicotine from cigarettes, when smoked by this procedure, to be compared and ranked. In the course of its studies, the task force demonstrated the value of comparing the analytical processes and their stability by use of the CORESTA monitor te
32、st piece for determining NFDPM and nicotine yields.Since the determinations of NFDPM and nicotine in sidestream smoke are by nature more complex and delicate than their counterparts performed on mainstream smoke, it is highly recommended to include a monitor test piece in the smoking plans, as is do
33、ne in mainstream smoke determinations. It is possible to use the CORESTA monitor or any other internally designed monitor test piece for this purpose. The use of an internationally recognized one is recommended.Cigarettes Determination of nicotine-free dry particulate matter and nicotine in sidestre

This International Standard does not purport to address all the safety p
35、roblems associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1 ScopeThis International Standard is applicable to the determination of to
36、tal particulate matter and to the subsequent determination of nicotine and nicotine-free dry particulate matter present in the sidestream smoke from cigarettes. The described method is specified using the ISO 3308 smoking parameters (puff volume, duration and frequency) and butt length, but it is te
