Cigarettes — Determination of water in the total particulate matter from the mainstream smoke with a smoking regime according to ISO 3308 (standard smoking regime) — Part 2: Karl Fischer method ISO/DIS 10362-2

Scope

This document specifies the use of the Karl Fischer method for the determination of water in the total particulate matter (TPM) of the mainstream smoke with a smoking regime according to ISO 3308 (standard smoking regime).
The smoking of cigarettes and the collection of TPM are carried out in accordance with ISO 4387. However, the method is also applicable to the determination of water in TPM obtained by non-standard smoking.
NOTE ISO 4387 specifies the use of gas chromatography for the determination of water in TPM solutions (see also ISO 10362-1). In countries not in a position to use the gaschromatographic method, the determination of water in TPM can be performed by the method described in this document and an appropriate note made in the expression of the results.
