Specification for radio disturbance and immunity measuring apparatus and methods - Part 2-5: In situ measurements for disturbing emissions produced by physically large equipment
CISPR 16-2-5:2008(E) deals with in situ electromagnetic disturbance measurements in any environment from physically large equipment and systems excluding networks. It covers both radiated and conducted emission phenomena, and does not deal with immunity tests. This technical report is intended to be applied primarily to such physically large equipment which are not under the scope of any existing emission standards (as for example CISPR 11 and CISPR 22). It serves only as a guideline on how to deal with emissions of that equipment at the particular location of installation. It does not establish any emission requirements. Due to the severe impact of the conditions existing at a particular location of operation and the use of the respective large equipment, however, it is not intended to use the measurements in the frame of type testing. Reference in-situ measurement distances will be given. This allows comparison of the measurement results with limits from existing relevant standards. The frequency range under consideration is from 9 kHz to 18 GHz.

Part 2-5: In situ measurements of disturbing emissions
produced by physically large equipment
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 16-2-5, which is a technical report, has been prepared by CISPR subcommittee H:
Limits for the protection of radio services.

Part 2-5: In situ measurements of disturbing emissions
produced by physically large equipment
1 Scope
This part of CISPR 16 deals with in situ electromagnetic disturbance measurements in any
environment from physically large equipment and systems excluding networks.
It covers both radiated and conducted emission phenomena, and does not deal with immunity
tests.
This technical report is intended to be applied primarily to such physically large equipment
which are not under the scope of any existing emission standards (as for example CISPR 11
and CISPR 22). It serves only as a guideline on how to deal with emissions of that equipment
at the particular location of installation. It does not establish any emission requirements.
NOTE 1 Although this technical report is intended to be applied to equipment which is not under the scope of any
existing emission standards, it may be used also in such cases in order to serve as additional information for
carrying out in situ measurements for any type of large equipment.
NOTE 2 Examples of large equipment are: production machines, conveyors, large displays, aircraft simulators,
traffic control equipment, etc.
Due to the severe impact of the conditions existing at a particular location of operation and
the use of the respective large equipment, however, it is not intended to use the
measurements in the frame of type testing.
NOTE 3 In general, type testing on large equipment is only possible at standardized test sites in a controlled
environment. The assessment results obtained under in situ conditions are only valid for the respective individual
large equipment actually measured at its particular place of installation. These results cannot be transposed to
other equipment of the same type, but installed at other locations.
Reference in-situ measurement distances will be given. This allows comparison of the
measurement results with limits from existing relevant standards.
The frequency range under consideration is from 9 kHz to 18 GHz.
Dealing with biological effects on living matter is excluded from this document.
