Abstract Cigarette conditioning is of great importance for its further physical and chemical analysis. Sufficient forced air flow is generally required for the conditioning of cigarettes, which is specified in the ISO and national standard. Therefore, we investigated the influence of the cigarette number, placing ways and locating positions on the air flow distribution in the constant climate chamber during the conditioning of cigarettes. In addition, conditioning effect of different types of cigarette was also investigated. It was found that the forced air flow was asymmetrically distributed in the chamber, and the distribution uniformity was barely affected by the abovementioned factors. Furthermore, equilibrium could be attained after 48h of conditioning, no matter what type of cigarette was or where the cigarettes were placed. This paper provides theoretical basis for the implementation of relevant standards in both industry and laboratory.
