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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.

INTERNATIONAL STANDARD ISO 15831:2004(E)
Clothing — Physiological effects — Measurement of thermal
insulation by means of a thermal manikin
1 Scope
This International Standard describes the requirements of the thermal manikin and the test procedure used to
measure the thermal insulation of a clothing ensemble, as it becomes effective for the wearer in practical use
in a relatively calm environment, with the wearer either standing or moving.
NOTE This thermal insulation, among other parameters, can be used to determine the physiological effect of clothing
on the wearer in specific climate/activity scenarios.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
clothing ensemble
group of garments worn together on the body at the same time
2.2
thermal insulation of clothing
temperature difference between the wearer's skin surface and ambient atmosphere divided by the resulting
dry heat flow per unit area in the direction of the temperature gradient where the dry heat flow consists of
conductive, convective and radiant components
NOTE Depending on the end use of the clothing, different thermal insulation values can apply.
2.2.1
total thermal insulation of clothing
I
t
total thermal insulation from skin to ambient atmosphere, including clothing and boundary air layer, under
defined conditions measured with a stationary manikin
2.2.2
resultant total thermal insulation of clothing
I
tr
total thermal insulation from skin to ambient atmosphere, including clothing and boundary air layer, under
defined conditions measured with a manikin moving its legs and arms

4 Principle
The components of the clothing ensemble to be tested are placed on the manikin in the same arrangement as
in practical use.
The manikin, in the shape and size of an adult human body and, for the measurement of I , with movable legs
tr
and arms, is internally heated to a constant skin surface temperature, uniform over its body. The manikin is
placed in a climatic chamber where defined air temperature and air speed can be set, and air humidity
controlled.
There will be a dry heat flow from the manikin's skin surface area through the clothing into the ambient air,
which is measured after steady-state conditions have been reached. From this heat flow, related to the nude
manikin's body surface area, the clothing ensemble's thermal insulation can be calculated, considering the
temperature difference between the manikin's skin surface and the ambient air.
The measurement is performed with the manikin stationary and/or moving its legs and arms, with a defined
number of movements per minute and a defined stride length.
The insulation values obtained include the thermal insulation provided by the clothing and the adhering air
layer around the body. They apply only to the particular clothing ensemble, as tested, and to the specific
conditions of the test, particularly with respect to the air movement around the manikin.

5 Apparatus
5.1 Manikin
5.1.1 Size and shape
The manikin, made from metal or plastic, shall be constructed to simulate the body of an adult human, i.e. it
shall consist of an anatomically formed head, chest, abdomen, back, buttocks, arms, hands (preferably with
fingers extended to allow gloves to be worn), legs and feet. The manikin shall consist of at least 15 body
segments, each independently controlled with regard to surface temperature and monitored for heat flow.
These 15 body segments shall be arranged as shown in Figure 1. If the manikin consists of more than
20 body segments, in the evaluation of the measured data, adjacent segments shall be combined using
Equation (3), in order to approximate the segment arrangement shown in Figure 1.
Figure 1 — Schematic arrangement of the manikin's body segments
2
The body height of the manikin shall be (1,70 ± 0,15) m, with a body surface area of (1,7 ± 0,3) m .
The manikin's body proportions should correspond to those required for standard sizes of garments, because
deviations in fit will affect the results.
