BS ISO 21330:2018 is applicable to cigarettes with nicotine-free dry particulate matter (NFDPM) yields between 1 mg/cigarette and 15 mg/cigarette.
These studies have shown that similar yields were obtained when comparing data from Tedlar bag trapping with those from cooled impinger traps, the latter method being used by the majority of laboratories. It has been decided that the CRM would be based on collecting the selected volatiles from mainstream cigarette smoke in cryogenically cooled impinger traps containing methanol.The impinger solutions were fortified with benzene- D6 and analysed by gas chromatography/massspectrometry (GC-MS).
BS ISO 21330:2018 was produced after a 2009 collaborative study involving 20 laboratories from12 countries using the ISO 3308 smoking regime. Further data were provided for the same selected volatile substances from 10 samples with different tar yields from a 2012 collaborative study, which involved 16 laboratories from 11 countries.
BS ISO 21330:2018 includes recommendations about critical steps that should be controlled to provide data as robust and consistent as the repeatability and reproducibility data provided in the ISO standard.Statistical evaluations carried out according to ISO 5725-1 and ISO 5725-2 are included.
