Part 3: CISPR technical reports

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".
CISPR 16-3, which is a technical report, has been prepared by CISPR subcommittee A:
Radio interference measurements and statistical methods.
This second edition of CISPR 16-3, together with CISPR 16-4-1, CISPR 16-4-3 and
CISPR 16-4-4 cancels and replaces the first edition of CISPR 16-3, published in 2000, and
its amendment 1 (2002). It contains the relevant clauses of CISPR 16-3 without technical
changes.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A bilingual version of this publication may be issued at a later date.

The committee has decided that the contents of this publication will remain unchanged until

2006. At this date, the publication will be

• reconfirmed;
• withdrawn;
• replaced by a revised edition, or

• amended.
The text of this report is based on the following documents:

INTRODUCTION
CISPR 16-1, CISPR 16-2, CISPR 16-3 and CISPR 16-4 have been reorganised into 14

parts, to accommodate growth and easier maintenance. The new parts have also been

renumbered. See the list given below.

Measurement instrumentation specifications are given in five new parts of CISPR 16-1,
while the methods of measurement are covered now in four new parts of CISPR 16-2.
Various reports with further information and background on CISPR and radio disturbances
in general are given in CISPR 16-3. CISPR 16-4 contains information related to
uncertainties, statistics and limit modelling.

Part 3: CISPR technical reports

1 Scope
This part of CISPR 16 contains specific technical reports and information on the history of

CISPR.
Over the years, the CISPR prepared a number of recommendations and reports that have

significant technical merit but were not generally available. Reports and recommendations
were for some time published in CISPR 7 and 8.
At its meeting in Campinas, Brazil, in 1988, subcommittee A agreed on the table of contents
of part 3 and to publish the reports for posterity by giving the reports a permanent place in
part 3.
With the reorganization of CISPR 16 in 2003, the significance of CISPR limits has been
moved to CISPR 16-4-3, whereas recommendations on statistics of disturbance complaints
and on the report on the determination of limits has been moved to CISPR 16-4-4. The
contents of Amendment 1 (2002) has been moved to CISPR 16-4-1.
