Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction

In many countries regulation of vapour products require reporting of 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

was written on the basis of the results obtained from interlaboratory studies conducted in 2015 and

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

[2][3]

parameters used to collect the aerosolised vapour should be evaluated and documented for each

analysis.

1 Scope

This document defines the method of measurement of the masses of e-liquid vaporised and the aerosol

collected from vapour product(s).

It does not specify the vapour product(s), the vapour product(s) operational settings or, e-liquid to be

3.2
puff block
finite series of sequential puffs as defined by the user or by the test request

EXAMPLE Puff block 1: puffs 1 to 50, puff block 2: puffs 51 to 100, puff block 3: puffs 101 to 150

3.4
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, 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;
