European foreword
This document (EN 17746:2023) has been prepared by Technical Committee CEN/TC 437 “Electronic
cigarettes and e-liquids”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by November 2023, and conflicting national standards shall
be withdrawn at the latest by November 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: 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 the United
Kingdom.
1 Scope
This document specifies the method for the determination of nicotine delivery consistency of an
electronic cigarette over the duration of use of e-liquid in the reservoir or a battery charge.
This document:
— defines the equipment to be used;
— specifies the preparation of the e-cigarette samples for testing;
— specifies the aerosol generation process;
— specifies the analytical method;
— specifies the determination of the test result.
This document does not seek to demonstrate whether there is consistency of nicotine delivery between
e-cigarettes. The latter is the aim of a separate method under development, EN 17634 Electronic
cigarettes and e-liquids — Determination of nicotine delivery consistency over defined puff sequences of a
number of e-cigarettes of identical type [1]. Two separate methods have been developed to determine
consistency of nicotine delivery, pending regulatory clarity on the Tobacco Products Directive's
requirement to "deliver nicotine doses at consistent levels" [2].

3.1
electronic cigarette
e-cigarette
product, that vaporises e-liquid to generate an inhalable aerosol carried by air drawn through the device
by the user
Note 1 to entry: Electronic cigarette is also referred to as e-cig, vapour product, personal vapouriser or
ENDS/ENNDS.
Note 2 to entry: Electronic cigarette differs from tobacco products in that they do not contain tobacco.
3.2
e-liquid
base liquid, which may or may not contain nicotine and/or additives, intended for transformation into an
aerosol by an electronic cigarette
3.3
vaped until exhaustion
aerosol generation via vaping machine until a pre-determined endpoint
3.4
open system
electronic cigarette where the user fills a reservoir with e-liquid
3.5
aerosol collected mass
ACM
mass of aerosol collected on an aerosol trapping system from the operation of a vapour product by a
routine analytical vaping machine after a defined number of puffs
Note 1 to entry: Routine analytical vaping machine is described in ISO 20768.
3.6
vaping
action of generating an aerosol with an airflow from an electronic cigarette
3.7
aerosol
system of colloidal particles suspended in gas by the use of an e-cigarette
Note 1 to entry: Vapour is a generally accepted, but scientifically incorrect, term for aerosol.
3.8
nicotine
(S)-3-(1-methyl-2-pyrrolidinyl) pyridine, conforming to the Chemical Abstracts Service nomenclature

Note 1 to entry: Coils are made of metal, ceramic, or other resistive materials.
3.12
sequence
defined number of puffs for aerosol generation
4 Principle
The test specimens are vaped until exhaustion (of battery or e-liquid) on a routine analytical vaping
machine
