This part of ISO 10362 specifies the use of the Karl Fischer method for the determination of water in cigarette smoke condensates. The smoking of ciga-rettes and collection of mainstream smoke are normally carried out in accordance with ISO 4387. However, the method is also applicable to the deter-mination of water in smoke condensates obtained by non-standard smoking.
NOTE 1 ISO 4387 specifies the use of gas chromatogra-phy for the determination of water in smoke condensate solutions (see also ISO 10362-1). In countries not in a pos-ition to use the gas-chromatographic method, the determi-nation of water in smoke condensate should be performed by the method described in this part of ISO 10362 and an appropriate note made in the expression of the results.
