Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not

This document was prepared by Technical Committee ISO/TC 126, Tobacco and tobacco products.
This third edition cancels and replaces the second edition (ISO 10362-1:1999), which has been
technically revised. It also incorporates the Amendment ISO 10362-1:1999/AMD 1:2011. The main
changes compared to the previous edition are as follows:
— capillary column procedure as an alternative gas chromatographic procedure has been added;
— the estimates for the repeatability limits (r) and the reproducibility limits (R) has been updated.

Introduction
This document may be considered as part of a set of standards which describes the determination of
total and nicotine-free dry particulate matter (NFDPM) in total particulate matter from the mainstream
smoke. The set comprises ISO 3308, ISO 3402, ISO 4387, ISO 8243, ISO 10315 and this document.
Annex A provides information about the use of this method in conjunction or simultaneously with the
gas-chromatographic method of nicotine determination described in ISO 10315.
A bibliography is provided.
No machine smoking regime can represent all human smoking behaviour:
— it is recommended that cigarettes also be tested under conditions of a different intensity of machine
smoking than those specified in this document;
— machine smoking testing is useful to characterize cigarette emissions for design and regulatory
purposes, but communication of machine measurements to smokers can result in misunderstandings
about differences in exposure and risk across brands;
— smoke emission data from machine measurements may be used as inputs for product hazard
assessment, but they are not intended to be nor are they valid as measures of human exposure or
risks. Communicating differences between products in machine measurements as differences in
exposure or risk is a misuse of testing using ISO standards.
INTERNATIONAL STANDARD ISO 10362-1:2019(E)
Cigarettes — Determination of water in total particulate
matter from the mainstream smoke —
Part 1:
Gas-chromatographic method
1 Scope
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.
2 Normative reference

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

analytical smoking machine

4 Principle
The total particulate matter from the mainstream smoke is dissolved in a solvent containing an internal
standard. The water content of an aliquot of the solution is determined by gas chromatography, and the
water content of the whole of the total particulate matter from the mainstream smoke is calculated.
5 Reagents
Use only reagents of recognized analytical reagent grade.
5.1 Carrier gas, helium or nitrogen (see note in 7.2) or hydrogen (see note in 8.4).
5.2 Propan-2-ol, with maximum water content of 1,0 mg/ml.
5.3 Internal standard, ethanol or methanol (of purity at least 99 %).
5.4 Extraction solution, propan-2-ol (5.2) containing an appropriate concentration of internal
standard (5.3), normally in the range of 1 ml/l to 5 ml/l.
Extraction solution not stored in a temperature-controlled laboratory shall be allowed to equilibrate to
(22 ± 2) °C before use.
To prevent water being absorbed, the bulk extraction solution container shall be fitted with a water
trap and shall be kept sealed. The extraction solution shall be stirred continuously to ensure the
homogeneity of the water concentration.
5.5 Reference substance, complying with grade 2 of ISO 3696:1987, or better.
5.6 C
