The work of preparing Internati

9、onal Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with IS

10、O, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical co

11、mmittees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the

13、 I SO 3002 All irhgts seredevrIntroduction Studies to determine the nicotine-free dry particulate matter (NFDPM) and nicotine of smoking articles made by consumers have been reported in the literature (see Bibliography, references 1 and 2). The studies show that consumers make smoking articles that

14、are extremely variable in terms of mass, diameter, density and size. The articles are frequently badly made and have very loosely filled ends. Great care must be taken when handling them. It is necessary that any study should ensure that the consumers chosen are experienced in hand-rolling smoking a

15、rticles, that the number of smokers studied is large, and that the articles made are correctly sampled and carefully transported to the testing laboratory. The survey can be conducted either by providing tobacco and wrappers or the consumers can be asked to provide their own. Evidence in reference 3

16、 shows that free tobacco provision leads to the use of more tobacco and higher smoke yields from the articles. On the other hand, non-provision leads to less well-controlled making conditions particularly with respect to tobacco moisture content. This factor is also known to affect article smoke yie

24、 selected. The panel members make fine-cut smoking articles (FCSAs). The samples are collected and packaged. The moisture content, draw resistance, NFDPM and nicotine yields of the FCSAs are determined according to methods specified in ISO 15592-3. 5 Consumer panel selection Choose panel members fro

25、m consumers who regularly make and smoke FCSAs at least once a day, preferably from the type of fine-cut tobacco and wrapper being studied. Select the panel so that it is representative in socio-demographic terms and in quantity of tobacco used per week. A minimum panel size of 100 is required, but

26、select a larger size if there is an intention to sub-classify the data. NOTE Pilot studies with a sample size of 40 may permit approximate findings. However, a study of 100 consumers is required to obtain satisfactory confidence limits. 6 Making FCSAs The Introduction discusses whether tobacco and w

27、rappers should be supplied to the consumers. If they are to be supplied, then the tobacco to be used to make FCSAs shall be supplied at the moisture content at which it is normally sold. If the consumers are to supply their own tobacco and wrappers, they shall be asked to use their normal tobacco an

28、d wrappers. Each consumer shall be asked to make a minimum of 25 FCSAs and identify the intended mouth end. From these, 20 samples shall be taken at random and used to determine smoke yields; two shall be used to determine the moisture content of the tobacco and the remainder shall be used to test d

29、raw resistance and to serve as spares in case of damage. For a more accurate determination, 45 samples shall be made to allow for two smoking runs of 20 FCSAs per consumer. NOTE Increasing the sample size to 45 may present a risk that the consumers would not take sufficient care over the making and

30、consequently lead to FCSAs that are not truly representative. The consumers should ideally be asked to make the FCSAs in their natural environment and by their normal manner of making. They should be required to make one for sampling and then a second one for smoking at the time when they wish to sm

31、oke until the number required for the study has been made. Sealable foam-lined containers shall be provided to protect and store the FCSAs as they are made. BSISO21147:20032IS:74112 O3002(E) I SO 3002 All irhgts seredevr 37 Laboratory analyses Condition the FCSAs according to ISO 15592-2, keeping se

32、parate those made by each consumer. Inspect the FCSAs made by each consumer for physical defects. Defective FCSAs shall not be used for smoke analysis but can possibly be used to determine other properties. Identify each article for any subsequent reference without causing damage. Randomly select on

33、e FCSA per consumer batch for determination of moisture content. Weigh and record the mass of each of 20 of the remaining FCSAs 40 if two smoking runs are to be made. Prepare and smoke the FCSAs according to 9.6 to 9.9.3 of ISO 15592-3:2003. Because of the nature of consumer-made FCSAs, it is most i

34、mportant that they are undamaged when inserted into the holders for smoking. Care should be taken to avoid leaks and it may be necessary to use sealant or a longer insertion depth to do so. If possible, measure the diameter of the remaining FCSAs at three places along the length. Measure to the near

35、est millimetre at places 10 mm from each end and in the middle. Express the result as the mean of the three measurements. Where possible, select the FCSA holder bobbin and latex sleeve dimensions appropriately (see ISO 15592-3:2003, 5.2). 8 Statistical evaluation Examine the data for statistical out

36、liers. Take great care to remove only those outliers arising from a known departure from procedure during the laboratory analysis because consumer-made articles are inherently very variable. 9 Test report 9.1 General The test report shall show the methods used and the results obtained. 9.2 Conduct o
