This part of ISO 10362 specifies a method for the gas-chromatographic determination of water in cigarette smoke condensates. The smoking of cigarettes and collection of mainstream smoke are normally carried out in accordance with ISO 4387. However, the method of this part of ISO 10362 is applicable to the determination of water in smoke condensates obtained by non-standard smoking.
NOTE In countries not in a position to use the gas-chromatographic method, the determination of water in smoke condensates should be performed by a Karl Fischer method (ISO 10362-2). In such cases, values obtained for water in smoke condensate may be used with the addition of a note made in the expression of the results.
