This document: — defines smoking parameters and specifies the conditions to be provided for the routine analytical machine smoking of cigarettes under specified intense conditions; — specifies the requirements for a routine analytical smoking machine conforming with these conditions; — specifies additional test methods for machine verification. Annex A gives examples of designs of smoking machine enclosures. NOTE The type of analytical smoking machine used could impact the mass of total particulate matter collected on the smoke trap. This might be due to either incomplete collection or evaporation of water and other volatile compounds from the smoke trap.
