Many Electronic Nicotine Delivery Systems (ENDS) employ integrated sensors to detect user puffing behavior and activate the heating coil initiate aerosol generation. The minimum puff flow rate duration at which ENDS device begins generate are important parameters in quantifying viable operating envelope of essential formulating a design experiments for comprehensive emissions characterization. An accurate unbiased method condition is needed quantify product characteristics across research laboratories. This study reports an accurate, measuring maximum aerosolization seven pod-style, four pen-style two disposable ENDS. ranged from 2.5 23 (mL/s) 0.5 1.0 (s) studied. was defined be when onset liquid aspiration evident, rates ranging 50 88 (mL/s). Results presented provide preliminary estimates effective each variation observed between products differing by various manufacturers has implications development standardized testing protocols data reporting required regulatory approval new products.
