15、mber bodies). The work of preparing International 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, governme
16、ntal and non-governmental, in liaison with ISO, 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 Dire
17、ctives, Part 2. The main task of technical committees 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 bod
18、ies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 18144 was prepared by Technical Committee ISO/TC 126, Tobacco and tobacco pro

Due to the nat
20、ure of the two aerosol phases, they rarely correlate well, and an accurate assessment of ETS levels in indoor air requires determining good tracers of both phases. Among the attributes of an ideal ETS tracer, one critical characteristic is that the tracer should “remain in a fairly consistent ratio
21、to the individual contaminant of interest or category of contaminants of interest (e.g. suspended particulates) under a range of environmental conditions.” (see 1). NOTEThe Bibliography gives full references to the literature cited. Solanesol, a isoprenoid alcohol, meets this requirement, since it r
22、emains in a constant ratio to respirable suspended particles (RSP) contributed by tobacco smoke over a variety of ventilation conditions and sampling durations (see 2). Ultraviolet particulate matter (UVPM) and fluorescent particulate matter (FPM), determined in accordance with ISO 155933, are trace
23、rs or markers which also fulfil this requirement. Airborne solanesol, however, is unique in that it is specific to tobacco smoke and is found only in the particulate phase of ETS. Its high molecular mass and low volatility make it extremely unlikely that any solanesol will be lost from the membrane
24、filter used for sample collection. Solanesol constitutes approximately by mass of the RSP of ETS (see 4 to 6), making it suitable for measurement at realistic smoking rates. Of the available ETS particulate phase markers (UVPM, FPM and solanesol), all are currently used and relied upon, but solaneso
