4 Principle

The test specimens are vaped until exhaustion (of battery or liquid) on a routine analytical vaping

machine with simultaneous collection of sequences of aerosol collected mass. If used, the consistency of

the laboratory vaping process and subsequent analytical procedures are controlled by using a

standardized clearomizer or a reference clearomizer together with a standardized e-liquid as specified

in EN 17375. The aerosol collected mass is used for the subsequent determination of nicotine. The

determined amount of nicotine per sequence can be used for the statistical determination of nicotine

delivery consistency.
5 Apparatus

Use the apparatus as defined by the ISO method for nicotine determination in aerosol. As long as this

standard is not published, use the items listed in Annex A.
