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
constitute an endorsement.

This second edition cancels and replaces the first edition (ISO 11092:1993), which has been technically
revised. It also incorporates Amendment 1 to ISO 11092:1993 (ISO 11092:1993/Amd.1:2012).

Introduction
This International Standard is the first of a number of standard test methods in the field of clothing
comfort.
The physical properties of textile materials which contribute to physiological comfort involve a complex
combination of heat and mass transfer. Each may occur separately or simultaneously. They are time-
dependent, and may be considered in steady-state or transient conditions.
Thermal resistance is the net result of the combination of radiant, conductive and convective heat
transfer, and its value depends on the contribution of each to the total heat transfer. Although it is an
intrinsic property of the textile material, its measured value may change through the conditions of test
due to the interaction of parameters such as radiant heat transfer with the surroundings.
Several methods exist which may be used to measure heat and moisture properties of textiles, each of
which is specific to one or the other and relies on certain assumptions for its interpretation.
The sweating guarded-hotplate (often referred to as the “skin model”) described in this International
Standard is intended to simulate the heat and mass transfer processes which occur next to human skin.
Measurements involving one or both processes may be carried out either separately or simultaneously
using a variety of environmental conditions, involving combinations of temperature, relative humidity,
air speed, and in the liquid or gaseous phase. Hence transport properties measured with this apparatus
can be made to
