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).

Introduction
In the early 21st century, the habit of water pipe smoking has spread worldwide especially among young
people. Formerly smoked mainly in Asia and Northern Africa, water pipe smoking has now spread in
European countries and the US. In this light, it is necessary to set up an International Standard for the
machine smoking of water pipe tobacco. Certain requirements, which are addressed in this document,
are based on experience and knowledge gained from the use of analytical water pipe tobacco smoking
machines. This is intended to lead to a better understanding of the products used and contribute to
better consumer information.
Although charcoal is typically used for water pipe smoking in the method described in this document,
the water pipe tobacco is heated by means of an electrical heater. This was decided in order to eliminate
the unpredictable influence of different types of charcoal on the measurement result. Nevertheless,
there is a general need to include this important aspect in a seperate method, for example, in view of the
determination of CO.
No machine smoking regime can represent all human smoking behaviour.
— Machine smoking testing is useful to characterize water pipe tobacco emissions for design and
regulatory purposes, but communication of machine measurements to smokers can result in
misunderstandings about differences in exposure and risk across brands.
— Smoke emission data from machine measurements may be used as inputs for product hazard
assessment, but they are not intended to be nor are they valid as measures of human exposure or
risks. Communicating differences between products in machine measurements as differences in
exposure or risk is a misuse of testing using ISO standards.

INTERNATIONAL STANDARD ISO 22486:2019(E)
Water pipe tobacco smoking machine — Definitions and
standard conditions
1 Scope
This document
— defines smoking parameters and specifies the standard conditions to be provided for the routine
analytical machine smoking of water pipe tobacco, where the water pipe tobacco sample is
electrically heated only and not combusted;
— specifies the requirements for a routine analytical smoking machine complying with the standard
conditions.
This document is only applicable for water pipe tobacco used in devices known as “arghile”, “hookah”,
“nargile” or “shisha” in which tobacco is heated, not combusted. Other types of water pipe tobacco that
are used in other devices such as “Chinese water pipe” are not covered.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https: //www .iso .org/obp
— IEC Electropedia: available at http: //www .electropedia .org/
3.1
test atmosphere
atmosphere to which a sample or test piece is exposed throughout the test
Note 1 to entry: It is characterized by specified values for one or more of the following parameters: temperature,
relative humidity and pressure, which are kept within the specified tolerances.
Note 2 to entry: The test may be carried out either in the laboratory or in a special chamber termed the “test
chamber”, or in the conditioning chamber, the choice depending on the nature of the test piece and on the test
itself. For example, close control of the test atmosphere may not be necessary if the change in properties of the
test piece is insignificant over the test period.
[SOURCE: ISO 3402:1999, 2.3, modified — Note 3 to entry has been omitted.]
3.2
restricted smoking
condition that exists when the connection tube of a water pipe is closed to the atmosphere between
successive puffs
