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.
ISO 13029 was prepared by Technical Committee ISO/TC 38, Textiles.

Introduction
The purpose of this International Standard is for testing textile fabrics that have moisture-management properties.
International Standards do not provide a detailed definition of Moisture Management Textiles. Here, moisture
management generally refers to a feature in which absorbed sweat is transported within the fabric and along
the fabric surface and is dried from the fabric surface.
The drying that takes place in textiles, which are designed to dry the absorbed sweat in a timely manner using the
capillary-tube phenomenon, progresses in a condition that is different from the drying that is generally practiced
after washing. This is because textiles intended for moisture-management properties show the feature of drying
the absorbed sweat at the same time as the sweat vapour is continuously allowed in from the human body.
Also, the drying of the textile progresses by evaporating only in the direction that is opposite to the side where
the sweat heated by the human body temperature contacts the skin. To distinguish between these two types
of drying, the condition in which textiles are dried after washing is specified as “steady state” while “dynamic
state” drying is the term used for the drying feature of the textile material with moisture-management properties.
To evaluate the drying condition of textiles under a dynamic state, the sweating-guarded hotplate (SGHP)
equipment specified in ISO 11092 has been modified and used. Distilled water is used to avoid the estimation
errors that can occur when applying artificial sweat to the SGHP.
This International Standard does not evaluate the physiological feature of textile materials. However, it can
provide information that can be used for comparison among textile materials by estimating their drying features
in limited environmental conditions.
INTERNATIONAL STANDARD ISO 13029:2012(E)
Textiles — Determination of drying rate in dynamic state by the
modified sweating-guarded hotplate
1 Scope
This International Standard specifies a method for measuring the drying rate of fabric products for sports,
leisure use or underwear, that have contact with the skin in their normal use, and other similar fabric products.
The method is not applicable to textiles that cannot be permeated by water vapour or for those textiles which
are more than 5 mm thick.
