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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62102, which is a technical report, was prepared by IEC technical committee 108: Safety
of electronic equipment within the field of audio/video, information technology and
communication technology, previously organized as IEC technical committee 74: Safety and
energy efficiency of IT equipment.
This second edition cancels and replaces the first edition published in 2001. This edition
constitutes a technical revision. The principal changes in this edition as compared with the first
edition of IEC 62102 are as follows (small changes are not listed):
− this 2nd edition was updated to accord with IEC 60950-1:2001;
− RFT (remote feeding telecommunication) circuits from IEC 60950-21 have been added;
– 4 – TR 62102 IEC:2005(E)
− in Annex B more interfaces have been added;
− in Annex B the category of xDSL interfaces have replaced ADSL interfaces.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
108/128/DTR 108/130/RVC
Full information on the voting for the approval of this technical report can be found in the report
on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
Terms printed in bold in the text are defined in Clause 3.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this document may be published at a later date.

INTRODUCTION
This technical report is a guide to the determination of the interface requirements for
equipment in terms of safety. It lists a number of interfaces and indicates the safety category of
each listed interface. This technical report does not contain sufficient detail for conformance
testing purposes, except when used in conjunction with product standards such as
IEC 60950-1 and IEC 60950-21.
The equipment safety standards IEC 60950-1 and IEC 60950-21 specify the requirements for
categories of circuits as SELV circuits, TNV circuits, RFT circuits and hazardous voltage
circuits (among others). For stand-alone equipment it is a relatively simple matter to determine
the different categories of circuits. However, an equipment which has data port interfaces is
intended to be connected to other equipment, either locally or via a network. In this case, the
safety categories of the interfaces which will be connected together have to be compatible with
each other. Furthermore, the category of the interface of the remote equipm
