ISO 3308:2012: defines smoking parameters and specifies the standard conditions to be provided for the routine analytical machine smoking of cigarettes; specifies the requirements for a routine analytical smoking machine complying with the standard conditions. Annex A specifies the ambient air velocities surrounding cigarettes in a routine analytical smoking machine, the mechanical design of the enclosures immediately surrounding them, and the methods of air velocity measurement including the location where air velocity is measured. Annex B describes, as an example, the special characteristics of a typical smoking machine incorporating a piston type of puffing mechanism. Annex C includes a diagram of a puff profile and illustrates definitions and standard conditions.
