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

Introduction

Vapour products are devices intended for human use, most of which contain electronic components

which vaporize a liquid to generate an aerosol carried by the air drawn through the device by the

user. The devices are designed either as a single piece or as modular, multiple component products, for

disposable, rechargeable and/or refillable use. In some cases, proprietary cartridges, pre-filled with

liquid, are replaced. Their use, often described as vaping, has grown substantially in recent years and

there are now regulations in place in a number of national and international jurisdictions requiring the

measurement of constituents of the aerosol produced by the devices.

This document has been developed to define and specify the requirements of machines used in

laboratories to draw air through the devices in order to generate aerosol for subsequent analytical

testing in a robust and reproducible manner.

There is a very wide range of vapour products available to consumers and limited reliable data

describing how they are used. The available data demonstrates significant intra- and inter-consumer

variation in behaviour. Consequently, no machine vaping regime can represent all human vaping

behaviour. As reliable data describing human vaping behaviour become available it may be appropriate

to test devices differently according to their design, or under conditions of different intensity to reflect

the range of human behaviour.

Machine testing is useful to characterize emissions for device development and regulatory purposes,

and may be used as inputs for product hazard assessment; however, it is not intended to be nor is it

valid as a measure of human exposure or risk. Communication of machine measurements to consumers

can result in misunderstandings about differences in exposure and risk across devices.
