Electronic cigarettes and e-liquids - Constituents to be measured in the aerosol of vaping products
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.

“Electronic cigarettes and e-liquids”, the secretariat of which is held by AFNOR.
Attention is drawn to the possibility that some of the elements of this document may be the subject of

1 Scope
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.

4 Mandate
TPD requires:
— “Manufacturers and importers of electronic cigarettes and refill containers shall submit a notification
to the competent authorities of the Member States“ […] ”The notification shall, depending on whether
the product is an electronic cigarette or a refill container, contain the following information:”[…];
— “(b) a list of all ingredients contained in, and emissions resulting from the use of, the product, by
brand name and type, including quantities thereof”.
5 What is the purpose of the emissions reporting?
5.1 General
There can be many reasons to measure constituents in vaping aerosol. Different purposes will focus on
different constituents to be measured and different aerosol generation protocols under which to measure
them. TPD requires submission of data across the range of vaping products in order to allow comparisons
between products, analogous to the required tar/nicotine/carbon monoxide measurements required for
cigarettes under the TPD. This requires:
a) constituents to be measured that can reasonably be expected to be present in all vaping products;
b) measurement under a standardised machine vaping regime to allow comparisons. This regime
should be consumer relevant.
5.2 TPD guidance
One of the purposes of the TPD is to help safeguard consumer safety. This would suggest emissions of
interest should be selected based on risk, i.e. a combination of inherent hazards and absolute abundance
in aerosol.
TPD definition: “‘emissions’ means substances that are released when a tobacco or related product is
consumed as intended,…”. (Emphasis added.) The proposal should thus address emissions of potential
toxicological concern, that can be expected when the products are used as intended, i.e. where the
products allow choice (e.g. of e-liquid, coil type, wattage and air flow settings, etc.), the interest is in
emissions that are produced when the compatible choices are made.
5.3 Hardware versus e-liquids
By mass, the bulk of the aerosol from vaping products are components that were present in the e-liquid
and have been aerosolised unchanged. Besides the e-liquid ingredients, this could include a small
contribution from e-liquid contaminants, potential reaction products between ingredients and potential
degradation products over time. Given the added aspects introduced by aerosolising the e-liquid (e.g.
choice of vaping device, machine vaping regime, analytical collection challenges), such compounds are
more appropriately measured in the e-liquid than in the aerosol.
Additionally some constituents in the aerosol derive from the hardware, i.e. from the materials the
different device parts are made of. These are thus hardware specific and measurement of them is relevant
to that hardware, not to e-liquids. The TPD already recognises that information submitted can differ
between e-liquids and hardware: “The notification shall, depending on whether the product is an
electronic cigarette or a refill container, contain the following information: …”
Another source of aerosol constituents is the thermal degradation products of the e-liquid that are
created from the aerosolisation process. These are dependent on the combination of e-liquid and
hardware used and should thus be measured for both vaping hardware and e-liquids, but with the
product combination clearly defined.
6 Existing regulatory guidance on compounds to be measured
6.1 TPD
The TPD itself contains no specifics on which emissions should be measured for vaping products.
However, assuming that emission measurement for cigarettes and vaping products will serve similar TPD
purposes, it is relevant to note that “emission levels” for cigarettes, as per paragraph 11 of the preamble,
refers to the tar, nicotine and carbon monoxide yields. This suggests an interest in a measure of the overall
aerosol yield, in nicotine in aerosol and in the main, high abundance, acute toxicant present in the aerosol
of all cigarettes.
6.2 European Commission guidance
No specific guidance form the European Commission exists. However, the TPD data dictionary electronic
cigarettes [3] makes provision for the potential notification of a number of named emissions (reference
data 10.4 in the data dictionary), listed in Table 1. The compounds have been sorted based on their most
likely source of origin if they were to be found in the vaping aerosol. Some could arise from more than
one source of origin and therefore appear in more than one row.
6.3 Member State guidance
One of the Member States, the UK, has published guidance on the emissions to be measured and notified
under the TPD. This guidance was discussed with the other Member States [4]. The guidance with regards
to the emissions to be measured for notification is based on the toxicologically most important emissions
expected to be present across the range of vaping products and indicates additional metals could be
included, depending on the construction and the material composition of the hardware. This guidance is
included in Table 1.
6.4 Existing voluntary standards/specification
Regulatory guidance exists in the form of the BSI PAS 54115 [6], a voluntary British Public Available
Specification that covers the emissions to be measured in vaping products. The BSI PAS 54115
recommendations are essentially the same as those taken over by the MHRA and these guidances have
therefore been combined in Table 1. An additional voluntary French Experimental Standard,
AFNOR XP D90-300-3 [5], has therefore also been included in Table 1.
6.5 FDA
The final published FDA deeming regulations indicates the FDA still needs to decide on what constituents
in aerosol should be reported on and exempts vaping products from emissions reporting obligations for
3 years.
