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

<p> La présente partie de l'ISO 10362 spécifie une méthode de dosage de l'eau dans les condensats de fumée de cigarettes par chromatographie en phase gazeuse. Le fumage de cigarettes et la collecte du courant principal de fumée sont normalement effectués conformément à l'ISO 4387. Néanmoins, la méthode décrite dans la présente partie de l'ISO 10362 est également applicable au dosage de l'eau dans les condensats de fumée obtenus par un fumage non normalisé.NOTE Dans les pays qui ne sont pas en mesure d'utiliser la méthode par chromatographie en phase gazeuse, il convient d'effectuer le dosage de l'eau dans les condensats de fumée selon la méthode de Karl Fischer décrite dans l'ISO 10362-2. En pareil cas, les valeurs obtenues pour l'eau dans les condensats de fumée peuvent être utilisées moyennant l'adjonction d'une note appropriée lors de l'expression du résultat. </p>
