Introduction
Technical investigation of vapour products requires determining aerosol collected mass (ACM) and
e-liquid vaporized mass (EVM) measurements in emissions. Therefore, there is a necessity to have an
International Standard in place to get reliable/comparable data on ACM and EVM in electronic cigarette
emissions.
[1]
The method in this document is based upon the CORESTA recommended method (CRM) 84, which
[2]
was written on the basis of the results obtained from interlaboratory studies conducted in 2015 and
[3]
2019 involving 18 and 11 laboratories, respectively.
This document has been developed to describe the procedures used to measure the amount of ACM
and EVM in the aerosol from vapour products utilizing a gravimetric method. The experimental design
[4][5]
parameters used to collect the aerosolised vapour should be evaluated and documented for each
analysis.

glass fibre filter pad overload
physical capacity of the glass fibre filter pad exceeded, which leads to a situation where the (volume of)
aerosol condensate is no longer retained by the glass fibre filter pad (trap) or can be introduced into the
glass fibre filter pad (be trapped)
Note 1 to entry: The glass fibre filter pad overloading is further described in Annex A.
4 Principle
Aerosol is generated from vapour products by using a routine analytical vaping machine according to
ISO 20768. The vapour products generate an aerosol from the e-liquid, which allows the gravimetric
measurement of e-liquid vaporised mass and the aerosol collected mass, respectively.
5 Apparatus
Usual laboratory apparatus and, in particular, the following.
5.1 Vaping machine, in accordance with ISO 20768.
5.2 Analytical balance, be precise at a minimum of 1 mg with a display precision of 0,1 mg.
5.3 Soap bubble flow meter, suitable to confirm the required puff volume.
5.4 Glass fibre filter pad, with specifications according to Annex B.
6 Procedure
6.1 General
EVM is calculated from the vapour product mass loss due to aerosol generations, while ACM is
calculated from the aerosol generated using a fixed number of puffs and puff blocks following standard
operational settings and environmental conditions in accordance with ISO 20768.
Prior to vaping, each aerosol collection system used should be checked to ensure that there are no leaks
and that the correct puff volume is obtained. Both leak and puff volume checks should be performed
according to the vaping machine manuf

Note 1 to entry: The glass fibre filter pad overloading is further described in Annex A.
4 Principle
Aerosol is generated from vapour products by using a routine analytical vaping machine according to
ISO 20768. The vapour products generate an aerosol from the e-liquid, which allows the gravimetric
measurement of e-liquid vaporised mass and the aerosol collected mass, respectively.
5 Apparatus
Usual laboratory apparatus and, in particular, the following.
5.1 Vaping machine, according to ISO 20768
5.2 Analytical balance, be precise at a minimum of 1 mg with a display precision of 0,1 mg
5.3 Soap bubble flow meter, suitable to confirm the (puff) volume of 55 ml
5.4 Glass fibre filter pad, with specifications according to Annex B
6 Procedure
6.1 General
EVM is calculated from the vapour product mass loss due to aerosol generations, while ACM is
calculated from the aerosol generated using a fixed number of puffs and puff blocks following standard
operational settings and environmental conditions according to ISO 20768.
Prior to vaping, each aerosol collection system used should be checked to ensure that there are no leaks
and that the correct puff volume is obtained. Both leak and puff volume checks should be performed
according to the vaping machine manufacturer’s recommendations. The amount of aerosol generated
depends on the nature of the vapour product, operational settings and the e-liquid. It is highly
recommended to perform a trapping efficiency study to verify the glass fibre filter pad has not been
overloaded. Trapping efficiency is described in more detail in Annex A.
6.2 Preparation
6.2.1 Vapour products
All the vapour products to be tested should be stored at room temperature. Vapour products with
rechargeable batteries shall be fully charged before the test and be operated in accordance with the
manufacturer recommendations.
6.2.2 Filter pad handling
The handling of the filter pad shall be done according to the following laboratory practises:
— Wear proper gloves (powder free) for all operations to prevent contamination;
