1 Scope
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.
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.
