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.
