EN 13309:2010 (E) 5 Introduction With the use of more electronic devices in areas where construction machinery operates, there is a need to ensure that construction machinery is provided with adequate immunity to external electromagnetic fields. As more construction machinery is fitted with electrical and electronic devices, it is necessary to ensure that the emissions of electromagnetic fields from the construction machinery meet acceptable limits. Electrical and high frequency disturbances emerge during the normal operation of many parts of the construction machinery devices and systems. They are generated within a large frequency range with different electrical characteristics and, by conduction and/or radiation, can be imparted to other electrical/electronic devices and systems of the construction machinery. Narrowband signals generated by sources of interference inside or outside the construction machinery can also be coupled in electrical/electronic systems whereby they can influence the normal function of electrical/electronic devices. Electrostatic discharges are relevant to construction machinery because control elements can be positioned outside the operator's station and potential differences can emerge at contact points. Conducted transients in power supply wiring have to be taken into account because construction machinery often represents open systems and several devices and/or components of construction equipment are combined with one another. While there are many existing standards for a variety of products and systems, the test method presented in this European Standard provides for the specific test conditions of construction machinery and the "electrical/electronic sub-assemblies or separate technical units" of construction machinery. The test method recognises that because of the size and usage of construction machinery, the arrangement of the construction machinery in the test facility needs to be responsive to the operating characteristics of these types of construction machinery. This European Standard provides test methods and criteria which are acceptable for construction machinery considering the unique characteristics and operating parameters of construction machinery. Because construction machinery has a number of systems that consist of components that may be used on a number of different construction machinery the approach of defining "electrical/electronic sub-assemblies or separate technical units" for these components is applied for the immunity and emissions test methods. This allows these components to be evaluated by the test method in existing laboratory facilities consisting of specially equipped shielded rooms. When electrical/electronic sub-assembly tests are conducted, it is necessary to consider the effects of the wiring systems used to connect the sub-assemblies into the construction machinery. The tests can also be conducted on the construction machinery. SIST EN 13309:2010
EN 13309:2010 (E) 6 1 Scope This European Standard provides test methods and acceptance criteria for the evaluation of the electromagnetic compatibility of construction machinery with respect to free trade of goods in the European Union. It deals with functional EMC requirements under typical EMC environmental conditions. This European Standard does not deal with safety requirements. Electrical and/or electronic component(s) or separate technical unit(s) intended to be fitted in construction machinery are also dealt with in this European Standard. The following electromagnetic disturbance phenomena are evaluated: broadband and narrowband electromagnetic interference; electromagnetic field immunity test; broadband and narrowband interference of electrical/electronic sub-assemblies; electromagnetic field immunity test of electrical/electronic sub-assemblies; electrostatic discharge; conducted transients. Construction machinery can have DC and/or AC internal electrical power supply systems. Machines that are designed to be supplied by the "Public Mains Network" are specifically excluded. 2 Normative references The following referenced documents are indispensable for the application of this document.

EN 13309:2010 (E) 10 4 Requirements 4.1 General requirements 4.1.1 Fulfilment of the requirements 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. 4.2.2 Broadband reference limits If measurements are made using the method described in Annex B using a construction machinery-to-antenna spacing of (10,0 ± 0,2) m, the emission reference limits shall be 34 dB (µV/m) (50 µV/m) in the 30 MHz to 75 MHz frequency band and 34 dB (µV/m) to 45 dB (µV/m) (50 µV/m to 180 µV/m) in the 75 MHz to 400 MHz frequency band, this limit increasing logarithmically (linearly) with frequencies above 75 MHz as SIST EN 13309:2010
EN 13309:2010 (E) 11 shown in Figure A.1. In the 400 MHz to 1 000 MHz frequency band the limit remains constant at 45 dB (µV/m) (180 µV/m). If measurements are made using the method described in Annex B using a construction machinery-to-antenna spacing of (3,0 ± 0,05) m, the emission reference limits shall be 44 dB (µV/m) (160 µV/m) in the 30 MHz to 75 MHz frequency band and 44 dB (µV/m) to 55 dB (µV/m) (160 µV/m to 562 µV/m) in the 75 MHz to 400 MHz frequency band, this limit increasing logarithmically (linearly) with frequencies above 75 MHz as shown in Figure A.2. In the 400 MHz to 1 000 MHz frequency band the limit remains constant at 55 dB (µV/m) (562 µV/m). On a single test specimen, the measured values, expressed in dB (µV/m) or (µV/m) shall be at least 2,0 dB or (20 %) below the reference limits. 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 (µV/m) (16 µV/m) in the
30 MHz to 75 MHz frequency band and 24 dB (µV/m) to 35 dB (µV/m) (16 µV/m to 56 µV/m) 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 (µV/m) (56 µV/m). 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 (µV/m) (50 µV/m) in the
30 MHz to 75 MHz frequency and 34 dB (µV/m) to 45 dB (µV/m) (50 µV/m to 180 µV/m) in 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 (µV/m) (180 µV/m). On a single test specimen, the measured values, expressed in dB (µV/m) or (µV/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 ton 577 µs, period 4 600 µs 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. SIST EN 13309:2010
