Puff count is determined by testing the product on a vaping aerosol collection machine (puffing engine). This machine is capable of carrying out 1000s of puffs that are identical.
The puffing engine is programmed to puff the product according to set puffing parameters, one of these being the length of time for each puff (puff duration). The counting of the puffs stops at the point that the weight of aerosol produced per puff drops significantly. The final puff count is based on the average of the 5 samples tested
