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 that 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. Because of 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 are 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. To learn more, or to purchase this report, go to the CISPR website. Testing for standards compliance is an ongoing challenge.
