The objective of the study is to determine the conditions permitting to smoke a pipe to its end in a reproducible way without lighting it too often and without reaching a too hot burn. The smoking conditions should approximate the human smoking conditions. The effects of the following factors on the combustion of tobacco were examined: volume, duration and frequency of puffs, the filling density of tobacco, and the intensity of lighting. The measured experimental criterions were a) the temperature of the smoke behind the pipe head and b) the residue of unburnt tobacco after smoking. The experiments were made on shag and coarse-cut tobaccos of different combustibility. Several combinations of smoking conditions are proposed and submitted for discussion.
