This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 437.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and

European foreword
This document (prEN 17957:2023) has been prepared by Technical Committee CEN/TC 437 “Electronic
cigarettes and e-liquids”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.

Introduction
This document has been developed to define an additional vaping regime and to specify its conditions of
application. Also, EN ISO 20768 describes inhalation of aerosol by filling the mouth before inhaling
deeper into the lung, commonly called mouth to lung vaping.
This additional regime is aimed to be representative of an inhalation through an electronic cigarette into
the lung, commonly called direct to lung inhalation.
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.
The methods exploring 25 devices, leading the technical characteristics used as criteria of application,
can be found in Soulet et al. (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 guidelines on when a direct to lung vaping regime should be used;
— Specifies technical requirements of the vaping device to be verified to use this regime;
— Specifies standard conditions and the profile of inhalation to be used for a direct to lung vaping
regime.
