8、, Germany). The responsible German body involved in its preparation was the Normenausschuss Lebensmittel und landwirtschaftliche Produkte (Food and Agricultural Products Standards Committee), Working Committee NA 057-04-01 AA Tabak und Tabakerzeugnisse. The standardization of the determination of th

9、e total particulate matter in cigarettes using a routine analytical smoking machine was included in the work programme of Technical Committee ISO/TC 126 during its constituent meeting in Berlin in 1968. After revision of the second edition of the International Standard ISO 4387, the third edition wa

10、s published in 2000. In 2008 an Amendment was published in which it was explained that no machine smoking regime can represent all human smoking behaviours. The DIN Working Committee decided to incorporate the 2008 Amendment to ISO 4387 into DIN ISO 4387, which had been published in 2000. The Workin

11、g Committee came to this decision in consideration of the necessary harmonization of international and national standards on smoking analysis. Amendments are indicated by a vertical line in the left margin next to the text. Attention is drawn to the possibility that some of the elements of this docu

16、ographic method 4 IntroductionCigarettes are manufactured to close tolerances using strict quality control procedures. However, all theconstituents involved in the manufacture are derived from natural products (tobacco, cigarette paper, tipping, etc.)and this results in a final product which is intr

17、insically variable. The complexity does not finish here because thecigarette is converted during smoking to cigarette smoke.Cigarette smoke is a complex mixture consisting of many individual chemical constituents. These compounds existas gases, vapours and condensed aerosol particles. Additionally,

18、various ageing processes, together withdiffusional and intersolubility effects, start occurring immediately after the formation of the smoke which furthercomplicate its composition.The quantitative measurement of nicotine-free dry particulate matter (NFDPM, sometime referred to as “tar“) is,therefor

19、e, dependent on its arbitrary definition.From the time that scientists have attempted to determine a value for NFDPM, many different methods have beenused. However, experience has shown some procedures to be more reliable and, with these factors in mind, during1988 and 1989, collaborative studies by

20、 Task Forces composed of members of the Cooperation Centre forScientific Research Relative to Tobacco (CORESTA) Smoke and Technology groups have been made on therepeatability and reproducibility of the determination of total and dry particulate matter from cigarettes.The studies show that improvemen

21、ts in repeatability and reproducibility result when some restrictions are placed onthe wide variety of methods and practices permitted by existing standard methods. Thus, this InternationalStandard, and the others which together form a complete set for the sampling, conditioning and determination of

22、nicotine, water and particulate matter from cigarettes, have been produced after much cooperation andcollaborative experimentation by many laboratories in many countries.CORESTA first published an International Standard for the machine smoking of cigarettes in 1968, and since thattime many improveme

23、nts in equipment as well as in procedure have been suggested.This International Standard incorporates these improvements and consequently represents the state of the art onthis subject and provides one set of procedures accepted as reference methods.This method is a machine method and allows cigaret

24、tes to be smoked using a strictly controlled set of parameters.Thus, it enables the NFDPM and nicotine from cigarettes, when smoked by this procedure, to be compared andranked on the basis of machine yield.No machine smoking regime can represent all human smoking behaviours: it is recommended that c

25、igarettes also be tested under conditions of a different intensity of machine smoking than those specified in this International Standard; machine smoking testing is useful to characterize cigarette emissions for design and regulatory purposes, but communication of machine measurements to smokers ca

26、n result in misunderstandings about differences in exposure and risk across brands; smoke emission data from machine measurements may be used as inputs for product hazard assessment, but they are not intended to be nor are they valid as measures of human exposure or risks. Communicating differences

27、between products in machine measurements as differences in exposure or risk is a misuse of testing using ISO standards.
