17、ons and immunity characteristics of aftermarket equipment (ESAs) which are referenced by Automotive EMC Directive 2004/104/EC, Annex I, 3.2.9, and which are not related to immunity-related functions of vehicles as defined in Automotive EMC Directive 2004/104/EC, Annex I, 2.1.12. Any equipment (or pa
18、rt of an ESA) which has a primary function of radio transmission and/or reception according to the ITU Radio Regulations are excluded from the scope of this publication. This European Standard covers the frequency range 9 kHz to 400 GHz. To date, it specifies limits and methods of measurement for co
19、nducted and radiated disturbances from ESAs in the frequency range 30 MHz to 1 GHz and immunity requirements for conducted transients. The assessment of an ESA needs to be performed only in the frequency ranges where limits are defined. The emission requirements have been selected so as to ensure th
20、at disturbances generated by ESAs operating normally do not exceed a level that could prevent the vehicle or apparatus external to the vehicle from operating as intended. Fault conditions are not taken into account. Not all disturbance phenomena have been included for testing purposes in this standa
21、rd but only those considered as relevant for the equipment covered by this standard. As ESAs covered by this standard are not related to immunity-related function, only the following electromagnetic disturbance phenomena are evaluated: broadband and narrowband radiated electromagnetic disturbances;
22、conducted transient disturbances; conducted transient immunity. Accessories that are not connected directly to the vehicle harness, but only via a special interface are normally excluded from vehicular EMC requirements. 2 Normative references The following referenced documents are indispensable for
23、the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

25、sociated electrical connections and wiring, which performs one or more specialized functions 3.2 broadband emission emission, which has a bandwidth greater than that of a particular measuring apparatus or receiver 3.3 narrowband emission emission, which has a bandwidth less than that of a particular
26、 measuring apparatus or receiver BS EN 50498:2010 5 EN 50498:2010 4 Abbreviations For the purposes of this document, the following abbreviations apply: DC Direct Current EM ElectroMagnetic EMC ElectroMagnetic Compatibility ESA Electronic Sub Assembly EUT Equipment Under Test 5 Test configuration Emi
27、ssion measurements shall be made in the operational mode(s) producing the largest emission in the frequency band being investigated consistent with normal applications. The ESA shall be configured in a manner, which is representative for normal/typical operation, where practical. Accessories that ar
28、e not connected directly to the vehicle harness, but only via a special interface are normally excluded from vehicular EMC requirements. In the case that accessory equipment may be connected to the ESA and may have an impact to the EMC performance of the ESA under testing, initial testing shall iden
29、tify the relevant loads/accessories to be considered during testing and the rationale used for selecting such accessories shall be stated in the test report. For specific types of apparatus for which specific EMC product (family) standards exist, the operating conditions and operational modes of the
30、 ESA shall be those defined by that specific standard, when applying this standard. EXAMPLES A broadcast receiver (radio/CD player) not intended for use in a vehicle would fall within the scope of EN 55013 and EN 55020. Therefore, for a car radio, the EUT configuration and operational mode(s) for em
31、issions would be defined in EN 55013, and the EUT configuration and operational modes for immunity tests would be defined in EN 55020. ITE equipment installed in vehicles, the EUT configuration and mode(s) defined in EN 55022 and EN 55024 apply. The configuration and mode of operation during the tes
32、ts shall be noted in the test report. 6 Applicability The requirements of Automotive EMC Directive 2004/104/EC, Annex I, 6.5, 6.6, 6.8 and 6.9, shall be fulfilled. An ESA shall meet these requirements in addition to the requirements of any other applicable harmonised European generic, product family
33、 or product EMC standards if it is intended for installation in motor vehicles. 7 Requirements 7.1 Broadband radiated disturbances The broadband electromagnetic radiation generated by the ESA representative of its type shall be measured by the method described in Automotive EMC Directive 2004/104/EC

37、 of the frequency. 7.3 Conducted transient disturbances The conducted transients emitted on the power cables of the ESA representative of its type shall be measured according to the method described in Automotive EMC Directive 2004/104/EC, Annex I, 6.9, on supply lines as well as to other connection
38、s of ESAs which may be operationally connected to supply lines. The test does not have to be carried out on ESAs that are not switched, contain no switches or do not include inductive loads. The limits of the transient disturbances shall be in accordance with those indicated in Table 3. Table 3 Limi

If the ESA is indire
41、ctly connected to the vehicle supply line via a DC adapter, then the test pulses shall be applied to the DC adapter. The test levels and functional status shall be in accordance with those indicated in Table 4. Table 4 Immunity test levels and functional status Test pulse number Immunity test level
