Specification for radio disturbance and immunity measuring apparatus and methods. In situ measurements of disturbing emissions produced by physically large equipment | Status: Current

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.
