scope:

This International Standard specifies additional test methods for routine analytical cigarette-smoking machines intended to check the conformity of these machines with ISO 3308. It only establishes additional test methods for smoking machines and does not deal with actual smoking, which is described in other International Standards. It is composed of three sections relating to: . the determination of pressure drop (clause 3); . the determination of puff profile (clause 4); . the determination of restricted smoking (clause 5). NOTE There are more possibilities to determine the aforementioned parameters. Systems giving the same results and accuracies can be used.
