EVAP - E-Vapour - 2013


  1. To identify areas of scientific research and conduct studies that will characterise e-liquids, e-vapour product emissions, and device properties and performance.
  2. To develop and publish methods and guides.
  3. To organise and conduct periodic proficiency/collaborative studies of identified constituents in e-liquids and e-vapour product aerosol.

The CORESTA E-Cigarette Task Force (changed to E-Vapour Sub-Group in 2016), formed in 2013, steadily grew to include over 55 members from 45 different organisations representing e-cigarette and e-liquid manufacturers, academia, regulators, equipment suppliers, and testing labs.

The initial objectives were:

  1. To create a document on worldwide product definition and definitions of terms to support harmonisation of nomenclature.
  2. To gather and share preliminary data on analysis relevant to e-cigarettes worldwide with a view to making recommendations for product testing.
  3. To define the relevant categories of products for potential further CORESTA studies.

The first objective "to create a document on worldwide product definition and definitions of terms to support harmonisation of nomenclature" has been completed with the publication of the Reference Report "E-Cigarettes: A Brief Description of History, Operation and Regulation."

The Task Force completed three studies focused on the testing of e-liquid composition, the parameters for collection of e-cigarette aerosol, and the analysis of e-cigarette aerosol for nicotine, glycerine, propylene glycol, and water.

Rob Stevens, Task Force Secretary from 2013-2016, made a presentation at the first FDA e-cigarette Workshop on December 10, 2014, the purpose of which was “to gather scientific information and stimulate discussion among scientists about electronic cigarettes”. At this same Workshop, Mike Ogden (Board member) was a panelist. Chuck Garner, Task Force Coordinator, was similarly a panelist at the second FDA e-cigarette workshop on March 9-10, 2015, that focused on “the impact of e-cigarettes on individual health”. Pierre-Marie Guitton, CORESTA Secretary General, presented the Task Force remit and accomplishments in UK and France meetings linked to the development of standards in Europe. Michael Meger, Vice-President of the Scientitifc Commission, also reported on the Task Force at an e-cig event in Germany. These presentations highlighted recent results for both e-liquid and e-cigarette aerosol studies, including discussions of major ingredients, analytical methods, selection of puffing parameters, and puff yields. Based on the Task Force’s findings, a 55 ml puff volume, 3 second puff duration, 30 second puff interval, and a square wave puff profile was recommended as a standardised approach for e-cigarette aerosol collection.

In addition, the Task Force completed a preliminary proficiency study conducted at 14 labs using eight different Disposable and Rechargeable products.

  • E-Liquid Preliminary Proficiency Study. Technical Report - March 2015

The following CORESTA E-Cigarette Task Force / E-Vapour Sub-Group reports have also been published:

  • 2014 Electronic Cigarette Aerosol Parameters Study. Technical Report - March 2015
  • E-Cigarettes: Assessment of Analytical Literature from 55 Studies Published Worldwide prior to November 2013 on Commercial E-Cigarettes. Reference Report - May 2014
  • E-Cigarettes: A Brief Description of History, Operation and Regulation. Reference Report - February 2014
  • 2014 Preliminary Aerosol Proficiency Study. Technical Report - October 2017
  • 2015 Collaborative Study for Determination of Glycerin, Propylene Glycol, Water and Nicotine in Collected Aerosol of E-Cigarettes. Technical Report - March 2017

The Task Force / Sub-Group also published two Recommended Methods:

  • CRM 81: Routine analytical machine for e-cigarette aerosol generation and collection - definitions and standard conditions
  • CRM 84: Determination of glycerin, propylene glycol, water, and nicotine in the aerosol of e-cigarettes by gas chromatographic analysis

A specific Working Group (WG2) has been created within the Sub-Committee 3 (SC 3) (Vape and Vapour Products) within ISO/TC 126 to deal with vaping machine standard conditions. WG2 is led by CORESTA and CRM81 is used as a working draft for the development of an international standard.

Given the growing interest and focus on e-cigarettes, the work of the group continued to evolve to address the increasing need for solid scientific methodologies and data.

In June 2015 the Task Force objectives were reviewed. In June 2016, the Task Force was changed to a Sub-Group, as its work and activities were viewed as being long-term, and its objectives revised accordingly. The new scope being wider than e-cigarettes, and in line with the name of the ISO/TC 126/SC 3, the group changed its name “E-Vapour.”

Since the change in status, the Sub-Group has published five Guides:

  • Guide No. 18: Sample Handling and Sample Collection of E-Cigarettes and E-Vapour Generating Products
  • Guide No. 22: Technical Guide for the Selection of Appropriate Intense Vaping Regimes for E-Vapour Devices
  • Guide No. 25: Technical Guide for Aerosol Collection and Considerations when Testing E-Vapour Product Technologies
  • Guide No. 26: Technical Guide for Designing E-Vapour Product Stability Studies
  • Guide No. 28: Technical Guide for Setting Method LOD and LOQ Values for the Determination of Metals in E-Liquid and E-Vapour Aerosol by ICP-MS

And four reports:

  • 2017 Collaborative Study on Carbonyl Containing Compounds in Electronic Cigarette Liquids. Technical Report - May 2018
  • 2019 Collaborative Study for the Determination of Formaldehyde and Acetaldehyde in E-Vapour Product Aerosol. Technical Report - November 2020
  • Metals Analysis Method for E-Liquids. Technical Report - May 2020
  • 2019 Collaborative Study: Reference Device for e-Cigarette Aerosol. Technical Report - January 2021

And one Recommended Method:

  • CRM 96: Determination of Formaldehyde and Acetaldehyde in E-Vapour Product Aerosol
