The requirements of this European Standard are met by construction machinery, and the electrical/electronic sub-assemblies when the requirements in 4,2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8 and 4.9, as applicable, are fulfilled. The user of this European Standard may choose either the clauses pertaining to the complete construction machinery, or those clauses pertaining to the electrical/electronic sub-assemblies. When the clauses pertaining to the electrical/electronic sub-assemblies are chosen, to fulfil the requirements of this European Standard, the electrical/electronic sub-assemblies shall be installed on the construction machinery In conformity with relevant provisions which have been considered in determining that the electrical/electronic sub-assemblies meet the requirements of the appropriate clauses of this European Standard.
The requirements of this European Standard are also deemed to be fulfilled when the construction machinery has no such equipment for which an immunity or interference test is required. In this case no tests are necessary (see Clause 5).
4.1.2 Test specimen
The test specimen may be chosen in accordance with the definitions given in 3.17 and/or 3.18.
Because the test of a single test specimen is to be used to judge the performance of a population of like construction machinery, the reference limits for emissions and immunity shall be made more restrictive by a 20 % reduction for emissions limits and a 25 % increase for immunity limits so as to account for variability of emission and immunity due to manufacturing variations of construction machinery, or ESA types and testing factors.
For a subsequent test on a like test specimen, conformity to the reference limits shall be accepted as fulfilment of the requirements of this European Standard.
For electrostatic discharge and conducted transients, the reference limits are valid for all testing of the test specimen.
4.1.3 Additional requirements for Immunity tests
When a test specimen is subjected to the immunity requirements, operator controls, and any automatic controls for the construction machinery and any attachments or machinery shall remain functional so as to provide continued control of the construction machinery. This also applies to secondary or shut-down systems which are intended to be operated when the primary control has failed,
4.2 Specifications concerning broadband electromagnetic emission radiated from
construction machinery
4.2.1 Method of measurement
The electromagnetic radiation shall be measured using the method described in Annex B at either of the defined antenna distances. The choice shall be made by the user of the standard.
4.3 SpecIfications concerning narrowband electromagnetic emission radiated from construction machinery
4.3.1 Method of measurement
The electromagnetic emission shall be measured using the method described in Annex C at either of the
defined antenna distances. The choice shall be made by the user of the standard.
4.3.2 Narrowband reference limits
If measurements are made using the method described in Annex C using a construction machinery-to-
antenna spacing of (10,0 ± 0.2) m, the emission reference limits shall be 24 dB (pVIm) (16 pV/m) in the
30 MHz to 75 MHz frequency band and 24 dB (pVlm) to 35 dB (pV/m) (16 pV/m to 56 iN/rn) in the 75 MHz to
400 MHz frequency band, this limit increasing logarithmically (linearly) with frequencies above 75 MHz as
shown in Figure A.3. In the 400 MHz to 1 000 MHz frequency band the limit remains constant at 35 dB (pV/m)
(56 pVIm).
If measurements are made using the method described in Annex C using a construction machinery-to-
antenna spacing of (3,0 ± 0,05) m, the emission reference limits shall be 34 dB (pVIm) (50 pV/m) in the
30 MHz to 75 MHz frequency and 34 dB (pVIm) to 45 dB (pVIm) (50 pV/m to 180 IN/rn) Ifl the 75 MHz to
400 MHz frequency band, this limit increasing logarithmically (linearly) with frequencies above 75 MHz as
shown in Figure A.4. In the 400 MHz to 1 000 MHz frequency band the limit remains constant at 45 dB (i.iVIm)
(180 IJV/m).
On a single test specimen, the measured values, expressed in dB (pV/m) or (pV/m), shall be at least 2,0 dB or (20 %) below the reference limits.
4.4 Specifications concerning the immunity of construction machinery to electromagnetic radiation
4.4.1 Test method
The immunity to electromagnetic radiation of the construction machinery shall be tested according to ISO 11451-1 and ISO 11451-2 with horizontal and vertical polarisation. The determination of the reference points and the operating modes shall be machine specific and noted in the test report. Immunity testing should be conducted as outlined in ISO 11451-1 except forward power may be used as the control regardless of the standing wave ratio of the system. The test report shall note which control method was used. The substitution method and the 80 % amplitude modulation (AM) with sinusoidal wave of 1 kHz is determined as a test method In the frequency band of 20 MHz to 800 MHz (see ISO 11451-1). Pulse Modulation (PM) with t 577 ps, period 4 600 .is is determined as test method in the frequency band of 800 MHz to 2 000 MHz (see ISO 11451-1).
NOTE 1 In the frequency range from 800 MHz to 1 000 MHz the amplitude modulation may alternatively be applied.BS EN 13309-2010 pdf download.
