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].
