6.4.1 Normal load conditions
Replace the existing title and text of this subclause by the following new titles and new text:
6.4.1 General arrangement of the EUT
6.4.1.1 General
Where not specified in the product standard, the EUT shall be configured as described below.
The EUT shall be installed, arranged and operated in a manner consistent with typical
applications. Where the manufacturer has specified or recommended an installation practice,
that practice shall be used in the test arrangement, where possible. This arrangement shall be
typical of normal installation practice. Interface cables, loads, and devices shall be connected
to at least one of each type of interface port of the EUT and, where practical, each cable shall
be terminated in a device typical of actual usage.
Where there are multiple interface ports of the same type, additional interconnecting cables,
loads and devices may have to be added to the EUT depending upon the results of
preliminary tests. Connecting a cable or wire to just one of that type of port may be sufficient.
The actual number of additional cables or wires may be limited to the condition where the
addition of another cable or wire does not significantly affect the emission level, i.e. varies
less than 2 dB, provided that the EUT remains compliant. The rationale for the selection of the
configuration and loading of ports shall be included in the test report.
Interconnecting cables should be of the type and length specified in the individual equipment
requirements. If the length can be varied, the length shall be selected to produce maximum
disturbance.
If shielded or special cables are used during the tests to achieve compliance, then a note
shall be included in the instruction manual advising of the need to use such cables.
Excess lengths of cables shall be bundled at the approximate centre of the cable with the
bundles 30 cm to 40 cm in length. If it is impractical to do so because of cable bulk or
stiffness, the disposition of the excess cable shall be precisely noted in the test report.
The results of an evaluation of EUTs having one of each type of module can be applied to
configurations having more than one of each of those modules. This is permissible because it
has been found that disturbances from identical modules are generally not additive in practice.
However the 2 dB criteria defined in this clause shall be applied.
Any set of results shall be accompanied by a complete description of the cable and equipment
orientation so that results can be reproduced. If specific conditions of use are required to
meet the limits, those conditions shall be specified and documented; for example cable length,
cable type, shielding and grounding. These conditions shall be included in the instructions to
the user.
Equipment that is populated with multiple modules (drawer, plug-in card, board, etc.) shall be
tested with a mix and number representative of that used in a typical installation. The number
of additional boards or plug-in cards of the same type may be limited to the condition where
the addition of another board or plug-in card does not significantly affect the emission level,
i.e. varies less than 2 dB, provided that the EUT remains compliant. The rationale used for
selecting the number and type of modules shall be stated in the test report.
A system that consists of a number of separate units shall be configured to form a minimum
representative configuration. The number and mix of units included in the test configuration
shall be representative of that used in a typical installation. The rationale used for selecting
units shall be stated in the test report.

CISPR16-2-3:2010/AMD2:2014 –5–
© IEC 2014
At least one module of each type shall be operative in each equipment evaluated in an EUT.
For a system EUT, at least one of each type of equipment that can be included in the possible
system configuration shall be included in the EUT.
The EUT position relative to the RGP shall be equivalent to that occurring in use. Therefore,
floor-standing equipment is placed on, but
