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 on the ISO list of patent declarations received (see www.iso.org/patents ).

This document was prepared by Technical Committee ISO/TC 126, Tobacco and tobacco products, Subcommittee SC 3, Vape and vapour products.

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.

1 Scope

This document:

• defines the parameters and specifies the standard conditions for a vaping machine for vapour products (as defined in 3.1);
• specifies technical requirements for the machine for routine analytical vaping, conforming with the standard conditions stated within Clause 4;
• does not specify the vapour product, the vapour product operation or the liquid to be used;
• does not specify the means for aerosol trapping, subsequent sample preparation or analyses of components in the trapped aerosol.
