This document specifies the atmosphere for the conditioning and testing of samples of tobacco and tobacco products.
It is primarily applicable to cigarettes; however, if not specified differently in other ISO standards, it can also be applied to tobacco, other tobacco products, and materials used in the manufacture of tobacco products for which prior conditioning is necessary. Standards for the conditioning and testing of other forms of tobacco, tobacco products, and materials can refer to all or part of this document.

This document specifies a method for the gas-chromatographic determination of nicotine in total particulate matter from the mainstream smoke. The smoking of cigarettes and the collection of mainstream smoke are carried out according to ISO 4387.
NOTE ISO 20778 and ISO 22253 provide the determination method of nicotine in smoke with an intense smoking regime.

This document specifies methods for the determination of total particulate matter and for the subsequent determination of nicotine-free dry particulate matter present in the smoke from cigarettes generated and collected using a routine analytical smoking machine.

ISO/IEC 17025:2017 specifies the general requirements for the competence, impartiality and consistent operation of laboratories.
ISO/IEC 17025:2017 is applicable to all organizations performing laboratory activities, regardless of the number of personnel.
Laboratory customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others use ISO/IEC 17025:2017 in confirming or recognizing the competence of laboratories.

ISO 3308:2012:
defines smoking parameters and specifies the standard conditions to be provided for the routine analytical machine smoking of cigarettes;
specifies the requirements for a routine analytical smoking machine complying with the standard conditions.  
Annex A specifies the ambient air velocities surrounding cigarettes in a routine analytical smoking machine, the mechanical design of the enclosures immediately surrounding them, and the methods of air velocity measurement including the location where air velocity is measured.
Annex B describes, as an example, the special characteristics of a typical smoking machine incorporating a piston type of puffing mechanism.
Annex C includes a diagram of a puff profile and illustrates definitions and standard conditions.

ISO 8243:2013 specifies two methods of providing representative samples of a population of cigarettes manufactured for sale. Different procedures are specified according to whether sampling is undertaken at the point of sale or at a factory.
Sampling "at one point in time" provides for appraisal of the chosen properties of the cigarettes on that occasion. Sampling is carried out within as short a period as possible.
Sampling "over a period of time" provides for on-going appraisals. It can be considered for practical purposes as a series of samples each taken "at one point in time".
ISO 8243:2013 provides information on the statistical basis for the treatment of data and gives estimates, based on practical experience, of the typical confidence intervals for nicotine-free dry particulate matter (NFDPM), nicotine and CO yields which may be found when a product is sampled in accordance with ISO 8243:2013 and smoked in accordance with the procedures specified in ISO 3308, ISO 3402, ISO 4387, ISO 8454, ISO 10315, ISO 10362‑1 and ISO 10362‑2.

ISO 8454:2007 specifies a method for the determination of carbon monoxide (CO) in the vapour phase of cigarette smoke.
