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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 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 bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

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  and ).
The studies show that consumers make smoking articles that are extremely variable in terms of mass,
diameter, density and size. The articles are frequently badly made and have very loosely filled ends. Greatcare must be taken when handling them.
It is necessary that any study should ensure that the consumers chosen are experienced in hand-rolling
smoking articles, that the number of smokers studied is large, and that the articles made are correctlysampled and carefully transported to the testing laboratory.
The survey can be conducted either by providing tobacco and wrappers or the consumers can be asked toprovide their own.
Evidence in reference  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 articlesmoke yields.
