Water pipe tobacco smoking machine — Definitions and standard conditions
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.

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.

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.

restricted smoking
condition that exists when the connection tube of a water pipe is closed to the atmosphere between
successive puffs
3.3
pressure drop
static pressure difference between the two ends of a pneumatic circuit when it is traversed by an air
flow under steady conditions in which the measured volumetric flow, under standard conditions, at the
output end is nominally 204 ml/s
Note 1 to entry: The pressure drop has to be determined with the required amount of water filled in the bottle
and the smoke trap (3.13) connected.
3.4
puff duration
interval of time during which the flow path of a water pipe is pneumatically connected to the suction
mechanism
