Summary
Introduction:
This text describes the CORESTa recommended method for the routine analysis of e-cigarette aerosol generation and collection. The method defines the parameters and standard conditions for the generation and collection of aerosol from e-cigarettes and specifies technical requirements for the machine used for aerosol generation and collection. The text also provides definitions for various terms used in the method and outlines the normative references.
Key points:
* The method is based on the findings reported in the CORESTa E-cigarette Task Force Technical Report, 2014 Electronic Cigarette aerosol Parameters Study.
* The method is applicable for the generation and collection of aerosol from e-cigarettes and other related products.
* The machine used for aerosol generation and collection should comply with standard conditions for pressure drop, puff duration, puff volume, puff frequency, puff profile, puff number, and puff termination.
* The machine should have a device to draw a fixed volume of air through the e-cigarette, produce a rectangular shaped puff profile, control puff volume, puff duration, and puff frequency, and compensate for changes in pressure drop.
* The e-cigarette holder should connect the e-cigarette to the machine in a leak-free manner, and the aerosol trap should retain at least 99.9% of all particles having a diameter equal to or greater than 0.3 μm.
* The machine should activate the e-cigarette and synchronize it with the puff, and terminate the aerosol generation and collection process after a pre-defined number of puffs or when the liquid or battery is exhausted.
* The temperature and relative humidity of the test atmosphere should be kept within specific limits during machine preparation and testing.
Main message:
The CORESTa recommended method for the routine analysis of e-cigarette aerosol generation and collection provides standard conditions and technical requirements for the machine used for aerosol generation and collection. By following this method, researchers and manufacturers can ensure consistent and reliable results in their studies and assessments of e-cigarette aerosols. It is crucial to follow the method's guidelines to maintain the quality and accuracy of the data generated from e-cigarette aerosol studies.
