Division 3.1.1

The technical service shall perform the test at the intervals specified in ISO DIS 11451-1:2003 throughout the frequency range 20 to 2 000 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 choose a reduced number of spot frequencies in the range, e.g. 27, 45, 65, 90, 120, 150, 190, 230, 280, 380, 450, 600, 750, 900, 1 300, and 1 800 MHz to confirm that the vehicle meets the requirements of this Annex.

If a vehicle fails the test defined in this Annex, it must be verified as having failed under the relevant test conditions and not as a result of the generation of uncontrolled fields.
