Testing of a commercial waterpipe electric heater and a research-grade waterpipe electric heater

摘要

IntroductionThe capability of a commercial waterpipe electric heater to simulatethe waterpipe charcoal heating system using waterpipe tobacco consumptionas a metric was evaluated, and a research-grade waterpipe electric heater tostandardize waterpipe tobacco emission testing was designed.MethodsThe experiment was conducted in two phases. In Phase 1, tobaccowas heated using either charcoal or a commercial electric heater. The tobaccotemperature was recorded during a 57-minute machine-smoking session andtobacco consumption was measured. In Phase 2, a similar procedure was followedusing a novel research-grade electric heater.ResultsIn Phase 1, tobacco consumption using either charcoal or the commercialelectric heater averaged 31.35% and 20.56%, respectively. In Phase 2, tobaccoconsumption using the research-grade electric heater, set at target temperaturesof 470, 430, 400, 380, 370 and 350°C, averaged 55.74, 41.22, 40.18, 39.10, 31.57and 26.14%, respectively.ConclusionsThe commercial electric heater did not reach consumption levels seenin the charcoal heating system, whereas the research-grade electric heater did andcan be used as part of a standardize waterpipe tobacco emission testing regimen.
