The work of preparing International Standards is normally carried out through ISO technical
11、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 ISO, also take part in the work. ISO collaborates closely with
12、the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed fo
13、r the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

18、0) was established by ISO/TC 126 in 2007 in response to a New Work Item Proposal by the British Standards Institute for the development of new regime for the machine smoking of cigarettes that was more intense than the then current ISO 3308:2000 and a subsequent questionnaire sent to TC 126 members.
19、 Twenty out of 26 members of TC 126 voted in favour of the following option: “to install a Working Group 10 dealing with an Intense Smoking Regime which shall start with the preparatory work. WHO is invited to participate with their technical experts. No draft Standard is expected to be presented by
20、 this group until the future method proposal of WHO has been taken into consideration.” At its fifth meeting, in December 2009, WG 10 decided to undertake a collaborative study using both ISO 3308 and Health Canada Intense smoking regimes. A steering group was established and the laboratory work was
21、 carried out in 2010. A final report on the study was approved by WG 10 and this ISO Technical Report has been prepared at the request of WG 10 at its tenth meeting, in June 2012.

25、late matter (NFDPM), nicotine and carbon monoxide (CO) from eight commercial cigarette products of different types, and two reference cigarettes/monitor test pieces (test articles) when smoked under both the ISO 3308 and the Health Canada Intense (HCI) (Health Canada, 1999) machine smoking regimes.

27、 summarized here. Participants and test results were coded by the ISO/TC 126 Secretariat to make them anonymous. Ten test articles were used: 8 commercial cigarettes of different designs, one reference cigarette, one monitor test piece, with ISO NFDPM yields ranging from 1 mg to 14 mg per test artic
28、le. The following test parameters were measured and recorded: total particulate matter (TPM), nicotine, water, nicotine-free dry particulate matter (NFDPM), carbon monoxide (CO), puff count, and cigarette mass. Comparison of data from the two smoking regimes (ISO and HCI). The design was based on a
29、set number of smoked test articles and smoking runs. Both linear and rotary smoking machines were used in the study. The protocol was sent to the participants in May 2010. All test results were reported between July and September 2010 to the ISO/TC 126 Secretariat and compiled for evaluation. 5 Part
30、icipants Thirty-five participants from 21 countries took part in the study with six laboratories contributing two data sets for each smoking regime (ISO and HCI). The participating laboratories, sorted by country, are listed in Table 1. Table 1 List of participants Company or Institute Country Japan

For HCI smoking, in addition to the ISO standards listed above, the puffing
32、 parameters and filter ventilation characteristics were modified from those described in ISO 3308 according to those described in the Health Canada method: Health Canada Method T-115. 7 Data were analysed according to ISO 5725 (all parts). 8 Puffing parameters and vent blocking conditions for each p
33、uffing regime are summarized in Table 3.Table 2 (continued) 4 ISO 2014 All rights reserved PD ISO/TR 19478-1:2014 ISO/TR 19478-1:2014(E) Table 3 Comparison of ISO and HCI smoking methods Smoking regime Puff volume Puff interval a Puff duration Ventilation zone blocking Number of test articles per pa

36、5 For ISO smoking, one test result was defined as the mean yield obtained from smoking 20 test articles in a single smoking machine run; therefore, from a rotary machine, it is the result from one run smoking 20 test articles and from a linear machine, it is the mean of four ports/channels, smoking
37、five test articles per port/channel. This was repeated on five separate days resulting in 100 test articles being smoked on both rotary and linear machines. For HCI smoking, the number of test articles smoked per Cambridge filter pad was reduced to avoid overloading the pad. Thus, one test result fr
38、om a rotary machine was the mean of two runs smoking 10 test articles each and from a linear machine, it was the mean of seven ports/channels, smoking three test articles per port/channel. This was repeated on five separate days resulting in 100 test articles being smoked on a rotary machine and 105
39、 on a linear machine. A summary of the different types of smoking machines is given in Table 5.

ISO 2014 All rights reserved 5 PD ISO/TR 19478-1:2014 ISO/TR 19478-1:2014(E) In total, 21 linear and 23 rotary smoking machines were included in this study (giving a total of 44 smoking machines). However, two participants
41、 used two different smoking machines for ISO and HCI smoking, so that the actual number for the statistical evaluation was 42. The very similar number of the two different types of smoking machine allows a formal statistical analysis of the results from different machine types (see 10.2). 8 Handling
42、 of basic data sets This clause describes the initial assessment by the organizing group of the basic measurement values provided by the participating laboratories. For the 42 smoking machines, 35 complete data sets were received. Five participants carried out a reduced smoking program due to techni
43、cal problems, lack of time, or delivery problems: No. 3: Test article I not smoked due to non-availability of 1R5F No. 7: Test article A not smoked under ISO smoking conditions No. 10: Test article D not smoked under ISO or HCI machine smoking conditions No. 12: Test article A not smoked under ISO o
44、r HCI machine smoking conditions No. 15: Test article E not smoked under ISO or HCI machine smoking conditions After reviewing the data sets No. 35 and No. 44, the following were realized by the statisticians: No. 35: HCI smoking performed under ISO regime, therefore results were not included in the
45、 evaluation No. 44: The wrong test article was used as test article I under ISO conditions, therefore results were not included in the evaluation. Furthermore, several data reports of the laboratories for the 10 test articles were not completed: No. 6: Cigarette mass: Error comment in test article G
46、 was corrected by the statisticians. No. 16: Calculation in some cells of the data sheet was carried out incorrectly. Errors were corrected by the statisticians. No. 22: ISO smoking regime: Blank cells for test articles A, B, and I which correspond to values below the limit of quantification (LOQ) w
47、ere reported by the participant. The mean was calculated by the statisticians based on the supplied number of data points. No. 26: Incorrect value for CO in test article mentioned by the authors and removed by the statisticians. No. 29: Data transfer into the data sheets not correctly carried out. I
48、t was corrected by the statisticians. No. 30: ISO smoking regime: In test article A of the original data set, one water value was below the LOQ. This value was treated as zero by the statisticians. No. 31: ISO smoking regime: In test article A, a water value was below the LOQ. This value was treated as zero by the statisticians. No. 37: ISO smoking regime: Missing data in the test articles A to E and H to J for all parameters.
