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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
With the improvement of consumers' living condition, wearable smart textiles came into being, and product
types emerge one after another. There are more and more interactions between textiles and touch-screen
electronic products, for example, touch-screen gloves, because of their novel functions, warmth and fashion,
have considerable sales in all markets around the world, whether in stores or online sales platforms, for
personal use or for workplace use.
a) b)
Figure 1 — An example of touch-screen textile product
a) knitted gloves, b) coated gloves
The fabric with touch screen function uses conductive materials, such as conductive fibres, through which
the human current is transmitted to the capacitive screen, so as to achieve the touch screen effect. As an
emerging commodity, the market demand for the products is strong, and the market prospect is unanimously
optimistic by investors. However, there are no corresponding test methods and relevant requirements
within the global standards, and the quality of this touchscreen textile product is various.
The development of test methods for measuring the performance of textile touch screen is suitable for all
types of fabrics with controllable capacitive screen, which meets the needs of the market at current stage
of scientific and technological development. The formulation of this standard will provide evidence for the
test and evaluation of the exchange effect between this type of textiles and touch screen electronic products
which fills the blank in this area.

with capacitive touchscreens
1 Scope
This document specifies a test method for determining the screen touch property of the textiles. The method
is applicable to all types of fabrics which are intended to be used for products that could handle the screen.
