This document specifies the method for the determination of nicotine delivery consistency from several e-cigarette of identical type.
Suitable sampling procedures are described for obtaining results from within a single production batch, as well as for sampling across batches. Sampling within a single batch is likely to be required when obtaining data for regulatory submission. Sampling across commercially produced batches will improve the understanding about consistency.

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 a test method for testing the capability of a cigarette, positioned on one of three standard substrates, to extinguish or to generate sufficient heat to continue burning, and thus potentially cause ignition of bedding or upholstered furniture. This document is only applicable to factory-made cigarettes that burn along the length of a tobacco column.
This is a performance-based document; it does not prescribe any design features of the cigarette that can lead to improved or degraded performance in the test method. The output of this method has been correlated with the potential for cigarettes to ignite upholstered furniture.

This document specifies the quality testing of e-liquids for vaping products in their fully produced form (“finished e-liquid”), whether containing nicotine or not. It is also applicable to testing of e-liquids when extracted from prefilled cartridges and similar e-liquid presentations to consumers.
This document is intended to be read in conjunction with CEN documents WI 00437001, General principles for manufacturing, filling and holding e-liquids for prefilled containers or products, and WI 00437023, E-liquid Ingredients.
NOTE   Testing for undesirable constituents is outside the scope of this document because their presence in final e-liquid is limited by controls at the ingredient level. The maximum level of undesirable constituents is set in the ingredient specification and monitored by testing at a frequency determined appropriate by the manufacturer.

This document specifies a method for the quantification of four tobacco specific nitrosamines (TSNAs) in the total particulate matter of cigarette mainstream smoke with the intense smoking regime specified in ISO 20778 by using reversed phase high performance liquid chromatography with tandem mass spectrometry (LC-MS/MS). The quantified TSNAs are: N-nitrosonornicotine (NNN), N-nitrosoanatabine (NAT), N-nitrosoanabasine (NAB) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK).

This document specifies a method for the determination of benzo[a]pyrene (B[a]P) in the total particulate matter (TPM) of cigarette mainstream smoke using gas chromatography/mass spectrometry (GC-MS) with methanol as extraction solvent. This method is specified using ISO 20778 smoking parameters. NOTE An alternative method for the determination of B[a]P is specified in ISO 23906-2 with a different clean-up using cyclohexane solvent and a shorter total analytical time.

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 specifies a method for the quantification of selected phenolic compounds by high performance liquid chromatography with fluorescence detection (HPLC-FLD) using ISO 3308 smoking parameters. The selected phenolic compounds are: hydroquinone, resorcinol, catechol, phenol, p-Cresol, m-Cresol and o-Cresol. This method is applicable to cigarettes with total particulate matter (TPM) yields between 1 mg/cigarette and 16 mg/cigarette.
