New Standard from Last Update.

1. SCOPE

This Indian Standard (Part 2) specifies the use of the Karl Fischer method for the determination of water in cigarette smoke condensates. The smoking of cigarettes and collection of mainstream smoke are normally carried out in accordance with IS 16023.

NOTE - IS 16023 specifies the use of gas chromatography for the determination of water in smoke condensate solutions [see also IS 16042 (Part 1)]. For labs not in a position to use the gas-chromatographic method, the determination of water in smoke condensate can be performed by the method described in this part of ISO 16042 and an appropriate note made in the expression of the results. However, the method is also applicable to the determination of water in smoke condensates obtained by non-standard smoking.
