Electronic cigarettes and e-liquids. Determination of nicotine delivery consistency over defined puff sequences within a single e-cigarette. | Status: Current

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 17634Electronic 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].
