CEN/TC 437/WG 4 - Requirements and test methods for emissions

This document:
—   defines a vaping regime for products suitable for use for a specific user inhalation behaviour: the direct to lung inhalation;
—   defines the parameters, technical requirements and standard conditions for a vaping machine for direct to lung vaping products;
—   specifies technical requirements of vaping devices suitable to be tested under this regime;
—   specifies the conditions under which this regime is suitable for use.

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].

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].

This document specifies reference e-liquids to be used to test emissions generated by electronic cigarettes [1].
This document applies to the reference e-liquids to be used when an electronic cigarette is sold empty, without an e-liquid, and where the product information or instructions for use are not specific in terms of the compositional characteristics of the e-liquid to be used with the device.

This document gives a list of constituents of interest proposed for measurement in the aerosol for the purpose of regulatory submission under the Directive 2014/40/EU (TPD) [2], for
- prefilled products such as disposable e-cigarettes and refill cartridges,
- e-liquids sold in refill containers,
- the following categories of hardware: coils or other heater elements of the vaping product, atomisers, rebuildable atomisers and all open tank or dripper products with inbuilt atomisers, including clearomisers.
This list is not intended to be comprehensive but rather, it represents the default minimum requirement. Depending on the device/liquid combination and the toxicological assessment other substances might have to be measured as well.
