Division 4.3 Measurements

The technical service shall perform the test at the intervals specified in the CISPR 25 (2nd edition 2002) standard throughout the frequency range 30 to 1 000 MHz.

Alternatively, if the manufacturer provides measurement to data for the whole frequency band from a test laboratory accredited to the applicable parts of ISO 17025 (1st edition 1999) and recognised by the Approval Authority, the technical service may divide the frequency range in 13 frequency bands 30–50, 50-75, 75-100, 100-130, 130-165, 165-200, 200-250, 250-320, 320-400, 400-520, 520-660, 660-820, 820-1 000 MHz and perform tests at the 13 frequencies giving the highest emission levels within each band to confirm that the ESA meets the requirements of this Annex.

In the event that the limit is exceeded during the test, investigations shall be made to ensure that this is due to the ESA and not to background radiation.
