Full title and description

ISO 10362-2:2013 — Cigarettes — Determination of water in smoke condensates — Part 2: Karl Fischer method. This international standard specifies the Karl Fischer titration procedure for measuring water content in cigarette smoke condensates; it is intended for application to mainstream smoke condensates and can also be used for non‑standard smoking conditions.

Abstract

ISO 10362-2:2013 describes dissolving smoke condensate in a suitable solvent and determining the water content of an aliquot by the Karl Fischer method. The collection of mainstream smoke is normally carried out in accordance with ISO 4387; the Karl Fischer procedure provides a quantitative measure of water in the condensate.

Scope

This part of ISO 10362 specifies the Karl Fischer titration method for determining water in cigarette smoke condensates. It applies to condensates obtained from mainstream smoke collected normally in accordance with ISO 4387, and is also applicable to condensates from non‑standard smoking procedures where required. The standard defines the analytical principle, sample preparation (dissolution of condensate in a solvent), titration and calculation/reporting of results.

Key topics and requirements

• Use of Karl Fischer titration for quantitative water determination in smoke condensate.
• Sample handling and dissolution of smoke condensate in a suitable, anhydrous solvent prior to titration.
• Reference to ISO 4387 procedures for generation and collection of mainstream smoke.
• Calibration, reagent standardization and calculation of water content (reporting conventions).
• Applicability to both standard and non‑standard smoking regimes (where condensates are produced).

Typical use and users

Analytical and quality laboratories in the tobacco industry, independent testing and contract laboratories, regulatory and public‑health laboratories, and R&D groups use this standard when precise determination of water in smoke condensates is required. It supports routine testing, method validation and inter‑laboratory comparability of water content data.

Related standards

ISO 10362 is a multi‑part set covering water determination in smoke condensates; Part 1 covers a gas‑chromatographic method (ISO 10362‑1). The smoke generation and collection practices referenced in ISO 10362‑2 are typically those in ISO 4387 (routine analytical smoking machine / condensate collection). ISO/TC 126 (Tobacco and tobacco products) is the responsible technical committee. A draft revision (ISO/DIS 10362‑2) has been recorded indicating revision activity.

FAQ

Q: What is this standard?

A: ISO 10362‑2:2013 is the ISO international standard that specifies the Karl Fischer titration method for measuring water in cigarette smoke condensates.

Q: What does it cover?

A: It covers sample dissolution of smoke condensate, Karl Fischer titration procedure, calibration and calculation/reporting of water content, and it references smoke collection procedures (normally ISO 4387). The method is applicable to mainstream smoke condensates and can be used with non‑standard smoking regimes.

Q: Who typically uses it?

A: Tobacco industry analytical and R&D labs, independent testing and regulatory laboratories, and standards committees involved in tobacco product analysis.

Q: Is it current or superseded?

A: ISO 10362‑2:2013 is the second edition published in October 2013 and replaced the 1994 edition; ISO indicates the document is published and under periodic review, and a draft revision (ISO/DIS 10362‑2) has been recorded, showing revision work in progress. Users should check official national or ISO catalogues for the very latest lifecycle status before regulatory or formal use.

Q: Is it part of a series?

A: Yes — ISO 10362 is published in parts (for example, Part 1 describes a gas‑chromatographic method). ISO 10362‑2 is Part 2 (Karl Fischer). The set of related tobacco analysis standards also includes ISO 10315, ISO 4387 and others maintained by ISO/TC 126.

Q: What are the key keywords?

A: Karl Fischer, water determination, smoke condensate, cigarettes, ISO 10362‑2, mainstream smoke, titration, tobacco analysis.
