Introduction
This document has been developed to define an additional vaping regime and to specify its conditions of
application. EN ISO 20768 describes the definitions and standard conditions for a routine analytical
vaping machine. However, a subset of vapour products characterized by low draw resistance, high power
and low heating coil resistance are not suitable for testing under EN ISO 20768 conditions.
This regime is suitable for robust and reproducible generation of aerosol from e-cigarettes specified for
direct to lung inhalation for subsequent analytical testing.
Due to the poor literature about puff topography of direct to lung vaping device users, this vaping regime
is based on physical lung properties and resting conditions. Puff volume is consistent with the tidal
volume (500 ml), the puff duration with a respiration rate of 12 breaths per minute (i.e. inhalation
duration of 2,5 s) leading to an average airflow rate estimated at 200 ml/s.
An example of a study exploring the technical characteristics used as criteria of application in this
document, in 25 devices, can be found in Reference (2021) [1].
1 Scope
This document:
— defines a vaping regime for products suitable for use for a specific user inhalation behaviour: the
direct to lung inhalation;
— defines the parameters, technical requirements and standard conditions for a vaping machine for
direct to lung vaping products;
— specifies technical requirements of vaping devices suitable to be tested u
