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.

The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be

• amended.
A bilingual version of this publication may be issued at a later date.
INTRODUCTION
Due to the trend towards a globalized, technological and connected society, there is a rising
demand for a new breed of technologies enabling low-priced, flexible and new-concept
products. Some conventional technologies (including silicon-based microelectronics) have
reached their limits due to their high fabrication costs and environmental issues. Armed with
new printing technologies and innovative materials, printed electronics has recently emerged
as a promising environmentally friendly alternative route for producing electronic products at
low cost and with new possibilities of such creative technologies as flexible electronics.
Currently, this technology is beginning to be used in the manufacturing of products such as
sensors, photovoltaic devices, signage, RFID, batteries, lighting devices, and some parts of
display devices, where cost, flexibility and recycling are critical issues.
For successful industrialization of printed electronics, not only the reliability and repeatability
in equipment and processes should be provided under global standardization, but also the
harmonization of terminology and definitions is a key element for a successful transition of
printed electronics to the market.

PRINTED ELECTRONICS –
Part 101: Terminology – Vocabulary
1 Scope
This part of IEC 62899 defines terms used in the field of printed electronics, addressing topics
including, but not limited to, materials, printing processes, and print characterization. It
focuses on terms that are of particular importance to printed devices. Therefore, terms that
are already defined in relation to conventional electronics materials, processes, devices,
components or systems that can be used in the field of printed electronics without alteration
are not included in this document. Similarly, established terms and definitions in relation to
printing technology that apply to the field of printed electronics are not included.
Definitions in this document are the primary reference for printed electronics terminology.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp

feature that is qualified by single directional parameters
3.2
2-d qualification feature
feature that is qualified by area-based qualification parameters
