FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
This part of IEC 62908 was developed in response to the demand for standardization of the
test methods for the endurance of touch displays.
The touch display is one of the most important interfaces between a user and a display.
Various technologies for touch displays have been developed, and it is expected that touch
display technology will make rapid progress in the future. This document is especially
effective for capacitive and resistive touch displays.
Durability is one of the most important aspects of touch display modules. Touch displays
connected to display modules are used under a variety of environmental conditions, including
indoor/outdoor, hot/cold, dry/humid, for long periods of time and may be subjected to severe
environmental stress.
This document describes standardized test methods to evaluate the durability of touch
displays subjected to environmental stresses. It is valid for research and development, quality
assurance, and comparison of devices when making purchasing decisions.

TOUCH AND INTERACTIVE DISPLAYS –

Part 13-10: Reliability test methods of touch displays –
Environmental durability test methods

1 Scope
This part of IEC 62908 specifies the methods for testing the environmental durability of touch
display modules, touch sensor modules and test pattern cells, and can be used for devices at
the production level, the prototype level or the trial model level when they are exposed to
environmental stress.
This document is applicable for touch displays that use capacitive or resistive detection
sensors. It may also be applicable to other types of sensors as well as to touch display
modules with both flat and flexible displays.
