BS ISO 10362-1:2019

1 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 ISO4387. 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 KarlFischer method (see ISO10362-2 ). 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.
