Describes smoking parameters and specifies the standard conditions to be provided for the routine analytical machine smoking of cigarettes and defines the requirements for a routine analytical smoking machine complying with the standard conditions.

This International Standard:

• 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.

AnnexA 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.

AnnexB describes, as an example, the special characteristics of a typical smoking machine incorporating a piston type of puffing mechanism.

AnnexC includes a diagram of a puff profile and illustrates definitions and standard conditions.
