E-cigarette vaping machine vs. conventional smoking machine – a compendium of differences in requirements and technology in regards to ISO 3308
E-products are a rapidly growing market. Starting with disposable or rechargeable products looking similar to conventional cigarettes, the market changed to more complex products. These so called second and third generation products offer a technical platform of much higher flexibility and customisation to the user.
Beside the fundamental discussions on how to regulate these products as a medical device or as a tobacco product, questions were raised about the presence of ingredients in the liquid and in the aerosol.
Certain studies have been performed and published, but it became obvious that nearly all of the publications were based on data that have been generated in different ways.
To get a better understanding of the products and the way they have to be analysed, CORESTA, with 9% members linked to e-products, launched a Task Force in 2012 to support harmonisation of nomenclature and to define the relevant categories of products with a view of making recommendations for product testing.
This presentation will summarise specific technical behaviours and design features of the e-products influencing the requirements of the design of a standard aerosol generator ("vaping machine“) in comparison to the existing conventional smoking machines. Physical properties such as size, weight, pressure drop or activation systems are discussed as well as their impact on the used puff generator, cigarette holder, termination system or aerosol traps. Finally the outlook to a first harmonised method is presented and some first results are shared.
