Water pipe tobacco — Determination of total collected matter and nicotine using a water pipe tobacco smoking machine
This document specifies methods for the determination of total collected matter and for the subsequent determination of nicotine present in the smoke from water pipe tobacco generated and collected using a water pipe tobacco smoking machine. This document is only applicable for devices known as "arghile", "hookah", "nargile" or "shisha" in which tobacco is only heated, not combusted. Other types, such as "Chinese water pipe", are not covered.

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
Tobacco smoke is a complex mixture consisting of many individual chemical constituents. These
compounds exist as gases, vapours and condensed aerosol particles. Additionally, various rapid ageing
processes, together with diffusional and intersolubility effects, start occurring immediately after the
formation of the smoke which further complicates its composition. These processes and effects are
particularly relevant to water pipe tobacco smoke where the smoke ages and passes through a water
trap before it reaches the smoker.
Historically, when tobacco products are smoked in a laboratory setting, the particulate matter in smoke
is collected on a glass fibre filter and this approach has been followed in this document for water pipe
tobacco smoking.
The parameters used for “puffing” on the laboratory water pipe used in this document are based on
published studies of human behaviour and data reported to the ISO/TC 126. It is convenient to use the
term “puffing”, however it is, in strict physiological terms, incorrect. Smokers of cigarettes and many
other tobacco products use a two-step process to draw the smoke from the product into the mouth (the
puff), followed usually by inhalation of ambient air into the lungs through either the nose or mouth.
Smokers of water pipes use a one-step process to inhale smoke directly into the lungs.
It is important to note that 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.

Water pipe tobacco — Determination of total collected
matter and nicotine using a water pipe tobacco smoking
machine
1 Scope
This document specifies methods for the determination of total collected matter and for the subsequent

a water pipe tobacco smoking machine.
This document is only applicable for devices known as “arghile”, “hookah”, “nargile” or “shisha” in which
tobacco is only heated, not combusted. Other types, such as “Chinese water pipe”, are not covered.

undated references, the latest edition of the referenced document (including any amendments) applies.

3.4
smoking run
specific smoking process (3.3) to produce such smoke from a sample of water pipe tobacco as is

3.5
test portion
water pipe tobacco prepared for a single determination
4 Principle
The water pipe tobacco is sampled and then smoked on a water pipe tobacco smoking machine with
collection of total collected matter in a glass fibre filter trap. The mass of the total collected matter
so collected is determined gravimetrically. The total collected matter is extracted from the trap for
determination of nicotine content by gas chromatography.
In laboratories that are not in a position to use gas-chromatographic methods, reference should be ma
