This document specifies a method for the determination of nicotine delivery consistency between e-cigarettes (devices, consumables and combinations). This document: - defines the equipment to be used; - specifies the preparation of the samples for testing; - specifies the aerosol collection process; - specifies the analytical method. Suitable sampling procedures are described for obtaining results from within a single production batch, as well as for sampling across batches. The method in this document does not seek to demonstrate whether there is consistency between puffs generated at the start or nearer the end of a tank fill or battery charge. The latter is the aim of a separate method under development, EN 17746 Electronic cigarettes and e-liquids – Determination of nicotine delivery consistency over defined puff sequences within a single e-cigarette [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].
