Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member 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, governmental 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.
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 for 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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

This document was prepared by Technical Committee ISO/TC 126, Tobacco and tobacco products.
This fourth edition cancels and replaces the third edition (ISO 4387:2000), which has been
technically revised. It also incorporates the Amendments ISO 4387:2000/Amd.1:2008 and
ISO 4387:2000/Amd.2:2017.
The main change compared to the previous edition is as follows:
— in 7.6.4, smoking and collecftion of particular matter has been modified by moving wording from
ISO 8454 into ISO 4387.

Introduction
Cigarettes are manufactured to close tolerances using strict quality control procedures. However, all
the constituents involved in the manufacture (such as tobacco, cigarette paper, tipping, etc.) are derived
from natural products and this result in a final product which is intrinsically variable. The complexity
does not end here because the cigarette is converted during smoking to cigarette smoke.
Cigarette smoke is a complex mixture consisting of many individual chemical constituents. These
compounds exist as gases, vapours and condensed aerosol particles. Additionally, various ageing
processes, together with diffusional and intersolubility effects, start occurring immediately after the
formation of the smoke which further complicates its composition.
The quantitative measurement of nicotine-free dry particulate matter (NFDPM, sometimes referred to
as “tar”) is, therefore, dependent on its arbitrary definition.
From the time that scientists have attempted to determine a value for NFDPM, a number of methods
have been used. However, experience has shown some procedures to be more reliable and, with these
factors in mind, during 1988 and 1989, collaborative studies by Task Forces composed of members of
the Cooperation Centre for Scientific Research Relative to Tobacco (CORESTA) Smoke and Technology
groups have been made on the repeatability and reproducibility of the determination of total and dry
particulate matter from cigarettes.
The studies show that improvements in repeatability and reproducibility result when some restrictions
are placed on the wide variety of methods and practices permitted by existing standard methods. Thus,
this document, and the others which together form a complete set for the sampling, conditioning and
determination of nicotine, water and particulate matter from cigarettes, have been produced after
much cooperation and collaborative experimentation by many laboratories in many countries.
CORESTA first published an International Standard for the machine smoking of cigarettes in 1968, and
since that time many improvements in equipment as well as in procedure have been suggested.
This document incorporates these improvements and consequently represents the state of the art on
this subject and provides one set of procedures accepted as reference methods.
This method is a machine method and allows cigarettes 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 and ranked on the basis of machine yield.
No machine smoking regime can represent all human smoking behaviours.
— It is recommended that cigarettes also be tested under conditions of a different intensity of machine
smoking than those specified in this document.
— Machine smoking testing is useful to characterize cigarette emissions for design and regulatory
purposes, but communication of machine measurements to smokers can result
