This Directive applies to the electromagnetic compatibility of  vehicles covered in Article 1, being vehicles or trailers (hereinafter referred to as vehicle(s))  as supplied by the vehicle manufacturer and to components or separate technical units intended for  fitment in vehicles. 2. Definitions2.1. For the purposes of this Directive: 2.1.1. 'Electromagnetic compatibility' means the ability of a vehicle or component(s) or separate  technical unit(s) to function satisfactorily in its electromagnetic environment without introducing  intolerable electromagnetic disturbances to anything in that environment. 2.1.2. 'Electromagnetic disturbance' means any electromagnetic phenomenon which may degrade the  performance of a vehicle or component(s) or separate technical unit(s). An electromagnetic  disturbance may be electromagnetic noise, an unwanted signal or a change in the propagation medium  itself. 2.1.3. 'Electromagnetic immunity' means the ability of a vehicle or component(s) or separate  technical unit(s) to perform without degradation of performance in the presence of specified  electromagnetic disturbances. 2.1.4. 'Electromagnetic environment' means the totality of electromagnetic phenomena existing at a  given location. 2.1.5. 'Reference limit' means the nominal level to which type approval and conformity of  production limit values are referenced. 2.1.6. 'Reference antenna' for the frequency range 20 to 80 MHz: means a shortened balanced dipole  being a half wave resonant dipole at 80 MHz, and for the frequency range above 80 MHz: means a  balanced half wave resonant dipole tuned to the measurement frequency. 2.1.7. 'Broadband emission' means an emission which has a bandwidth greater than that of a  particular measuring apparatus or receiver. 2.1.8. 'Narrowband emission' means an emission which has a bandwidth less than that of a particular  measuring apparatus or receiver. 2.1.9. 'Electrical/electronic system' means (an) electrical and/or electronic device(s) or set(s)  of devices together with any associated electrical connections which form part of a vehicle but  which are not intended to be type approved separately from the vehicle. 2.1.10. 'Electrical/electronic sub-assembly' (ESA) means an electrical and/or electronic device or  set(s) of devices intended to be part of a vehicle, together with any associated electrical  connections and wiring, which performs one or more specialized functions. An ESA may be approved at  the request of a manufacturer as either a 'component' or a 'separate technical unit (STU)' (see  Directive 70/156/EEC, Article 2). 2.1.11. 'Vehicle type' in relation to electromagnetic compatibility means vehicles which do not  differ essentially in such respects as: 2.1.11.1. the overall size and shape of the engine compartment; 2.1.11.2. the general arrangement of the electrical and/or electronic components and the general  wiring arrangement; 2.1.11.3. the primary material of which the body or shell (if applicable) of the vehicle is  constructed (for example, a steel, aluminium or fibreglass body shell). The presence of panels of  different material does not change the vehicle type provided the primary material of the body is  unchanged. However, such variations must be notified. 2.1.12. An 'ESA type' in relation to electromagnetic compatibility means ESAs which do not differ  in such essential respects as: 2.1.12.1. the function performed by the ESA; 2.1.12.2. the general arrangement of the electrical and/or electronic components, if applicable. 3. Application for EEC type-approval3.1. Approval of a vehicle type3.1.1. The application for  approval of a vehicle type, with regard to its electromagnetic compatibility pursuant to Article 3  (4) of Directive 70/156/EEC shall be submitted by the vehicle manufacturer. 3.1.2. A model for the information document is given in Annex IIA. 3.1.3. The vehicle manufacturer shall draw up a schedule describing all projected combinations of  relevant vehicle electrical/electronic systems or ESAs, body styles (1), variations in body  material (1), general wiring arrangements, engine variations, left-hand/right-hand drive versions  and wheelbase versions. Relevant vehicle electrical/electronic systems or ESAs are those which may  emit significant broadband or narrowband radiation and/or those which are involved in the driver's  direct control (see paragraph 6.4.2.3 of this Annex) of the vehicle. 3.1.4. A representative vehicle shall be selected from this schedule for the purpose of being  tested, in mutual agreement between the manufacturer and the competent authority. This vehicle  shall represent the vehicle type (see Appendix 1 to Annex IIA). The choice of vehicle shall be  based on the electrical/electronic systems offered by the manufacturer. One more vehicle may be  selected from this schedule for the purpose of being tested if it is considered by mutual agreement  between the manufacturer and the competent authority that different electrical/electronic systems  are included which are likely to have a significant effect on the vehicle's electromagnetic  compatibility compared with the first representative vehicle. 3.1.5. The choice of the vehicle(s) in conformity with paragraph 3.1.4 is limited to  vehicle/electrical/electronic system combinations intended for actual production. 3.1.6. The manufacturer may supplement the application with a report from tests which have been  carried out. Any such data provided may be used by the approval authority for the purpose of  drawing up the type-approval certificate. 3.1.7. If the technical service responsible for the type-approval test carries out the test itself,  then a vehicle representative of the type to be approved, according to paragraph 3.1.4 shall be  provided. 3.2. Approval of a type of ESA3.2.1. The application for approval of a type of ESA with regard to  its electromagnetic compatibility pursuant to Article 3 (4) of Directive 70/156/EEC shall be  submitted by the vehicle manufacturer or by the manufacturer of the ESA. 3.2.2. A model for the information document is given in Annex IIB. 3.2.3. The manufacturer may supplement the application with a report from tests which have been  carried out. Any such data provided may be used by the approval authority for the purpose of  drawing up the type-approval certificate. 3.2.4. If the technical service responsible for the type-approval test carries out the test itself,  then a sample of the ESA system representative of the type to be approved shall be provided, if  necessary, after discussion with the manufacturer on, for example, possible variations in the  layout, number of components, number of sensors. If the technical service deems it necessary, it  may select a further sample. 3.2.5. The sample(s) must be clearly and indelibly marked with the manufacturer's trade name or  mark and the type designation. 3.2.6. Where applicable, any restrictions on use should be identified. Any such restrictions should  be included in Annexes IIB and/or IIIB. 4. Type-approval4.1. Routes to type-approval4.1.1. Type-approval of a vehicleThe following  alternative routes to type-approval of a vehicle may be used at the discretion of the vehicle  manufacturer. 4.1.1.1. Approval of a vehicle installationA vehicle installation may achieve type-approval  directly by following the provisions laid down in paragraph 6 of this Annex. If this route is  chosen by a vehicle manufacturer, no separate testing of electrical/electronic systems or ESAs is  required. 4.1.1.2. Approval of vehicle type by testing of individual ESAsA vehicle manufacturer may obtain  approval for the vehicle by demonstrating to the approval authority that all the relevant (see  paragraph 3.1.3 of this Annex) electrical/electronic systems or ESAs have individually been  approved in accordance with this Directive and have been installed in accordance with any  conditions attached thereto. 4.1.1.3. A manufacturer, if he wishes, may obtain approval to this Directive if the vehicle has no  equipment of the type which is subject to immunity or emission tests. The vehicle shall have no  systems as specified in paragraph 3.1.3 (immunity) and no spark ignition equipment. Such approvals  do not require testing. 4.1.2. Type-approval of an ESAType-approval may be granted to an ESA to be fitted either to any  vehicle type or to a specific vehicle type or types requested by the manufacturer. ESAs involved in  the direct control of vehicles will normally receive type-approval in conjunction with a vehicle  manufacturer. 4.2. Granting of type-approval4.2.1. Vehicle4.2.1.1. If the representative vehicle fulfils the  requirements of this Directive, EEC type-approval pursuant to Article 4 (3), and if applicable,  Article 4 (4) of Directive 70/156/EEC shall be granted. 4.2.1.2. A model for the EEC type-approval certificate is given in Annex IIIA. 4.2.2. ESA4.2.2.1. If the representative ESA system(s) fulfil(s) the requirements of this  Directive, EEC type-approval pursuant to Article 4 (3), and if applicable, Article 4 (4) of  Directive 70/156/EEC shall be granted. 4.2.2.2. A model for the EEC type-approval certificates is given in Annex IIIB. 4.2.3. In order to draw up the certificates referred to in paragraph 4.2.1.2 or 4.2.2.2, the  competent authority of the Member State granting the approval may use a report prepared by an  approved or recognized laboratory or in accordance with the provisions of this Directive. 4.3. Amendments to approvals4.3.1. In the case of amendments to approvals granted pursuant to this  Directive, the provisions of Article 5 of Directive 70/156/EEC shall apply. 4.3.2. Amendment of a vehicle type-approval by ESA addition or substitution. 4.3.2.1. Where a vehicle manufacturer has obtained approval for a vehicle installation and wishes  to fit an additional or substitutional electrical/electronic system or ESA which has already  received approval pursuant to this Directive, and which will be installed in accordance with any  conditions attached thereto, the vehicle approval may be amended without further testing. The  additional or substitutional electrical/electronic system or ESA shall be considered as part of the  vehicle for conformity of production purposes. 4.3.2.2. Where the additional or substitutional part(s) has (have) not received approval pursuant  to this Directive, and if testing is considered necessary, the whole vehicle shall be deemed to  comply if the new or revised part(s) can be shown to comply with the relevant requirements of  paragraph 6 or if, in a comparative test, the new part can be shown not to be likely to adversely  affect compliance of the vehicle type. 4.3.2.3. The addition by a vehicle manufacturer to an approved vehicle of standard domestic or  business equipment, other than mobile communication equipment (*) which complies with Directive  89/336/EEC, and is installed according to the recommendations of the equipment and vehicle  manufacturers, or the substitution or removal thereof, shall not invalidate the vehicle approval.  This shall not preclude vehicle manufacturers fitting communication equipment with suitable  installations guidelines developed by the vehicle manufacturer and/or manufacturer(s) of such  communication equipment. The vehicle manufacturer shall provide evidence (if requested by the test  authority) that vehicle performance is not adversely affected by such transmitters. This can be a  statement that the power levels and installation are such that the immunity levels of this  Directive offer sufficient protection when subject to transmission alone, i.e. excluding  transmission in conjunction with the tests specified in paragraph 6. This Directive does not  authorize the use of a communication transmitter when other requirements on such equipment or its  use apply. A vehicle manufacturer may refuse to install in his vehicle standard domestic or  business equipment which complies with Directive 89/336/EEC. 5. Marking5.1. Every ESA conforming to a type approved pursuant to this Directive shall bear an  EEC type-approval mark. 5.2. This mark shall consist of a rectangle surrounding the letter 'e' followed by the  distinguishing number or letters of the Member State which has granted type-approval: 1 Germany2 France3 Italy4 the Netherlands6 Belgium9 Spain11 the United Kingdom13  Luxembourg18 Denmark21 Portugal23 GreeceIRL IrelandIt must also include in the vicinity of the  rectangle the four-digit sequential number (with leading zeros as applicable) - hereinafter  referred to as 'base approval number' - contained in Section 4 of the type-approval number shown on  the EEC type-approval certificate issued for the type of device in question (see Annex IIIB),  preceded by the two figures indicating the sequence number assigned to the most recent major  technical amendment to Directive 72/245/EEC on the date EEC component type-approval was granted. In  this Directive the sequence number is 02. 5.3. The EEC type-approval mark must be affixed to the main part of the ESA (e.g. the electronic  control unit) in such a way as to be clearly legible and indelible. 5.4. An example of the EEC type-approval mark is shown in Appendix 7. 5.5. No marking is required for electrical/electronic systems included in vehicle types approved by  this Directive. 5.6. Markings on ESAs in compliance with paragraph 5.3 need not be visible when the ESA is  installed in a vehicle. 6. Specifications6.1. General specification6.1.1.

If tests are made using the methods described in  Annex IX, the immunity test reference levels shall be 48 volts/m for the 150 mm stripline testing  method, 12 volts/m for the 800 mm stripline testing method, 60 volts/m for the TEM cell testing  method, 48 mA for the bulk current injection (BCI) testing method and 24 volts/m for the free field  testing method. 6.7.2.2. On the ESA representative of its type at a field strength or current expressed in  appropriate linear units 25 % above the reference limit, the ESA shall not exhibit any malfunction  which would cause any degradation of performance which could cause confusion to other road users or  any degradation in the driver's direct control of a vehicle fitted with the system which could be  observed by the driver or other road user. 7. Conformity of production7.1. Measures to ensure the conformity of production shall be taken in  accordance with the provisions laid down in Article 10 of Directive 70/156/EEC. 7.2. Conformity of production with regard to the electromagnetic compatibility of the vehicle or  component of separate technical unit shall be checked on the basis of the data contained in the  type-approval certificate(s) set out in Annex IIIA and/or IIIB of this Directive as appropriate. 7.3. If the authority is not satisfied with the auditing procedure of the manufacturer, then items  2.4.2 and 2.4.3 of Annex X to Directive 70/156/EEC and paragraphs 7.3.1 and 7.3.2 below shall  apply. 7.3.1. If the conformity of a vehicle, component or STU taken from the series is being verified,  production shall be deemed to conform to the requirements of this Directive in relation to  broadband radiated emissions and narrowband radiated emissions if the levels measured do not exceed  by more than 2 dB, (25 %) the reference limits prescribed in paragraphs 6.2.2.1, 6.2.2.2, 6.3.2.1  and 6.3.2.2 (as appropriate). 7.3.2. If the conformity of a vehicle, component or STU taken from the series is being verified,  production shall be deemed to conform to the requirements of this Directive in relation to immunity  to electromagnetic radiation if the vehicle, component or STU does not exhibit any degradation  relating to the direct control of the vehicle which could be observed by the driver or other road  user when the vehicle, component or STU is in the state defined in Annex VI, paragraph 4, and  subjected to a field strength, expressed in volts/m, up to 80 % of the reference limits prescribed  in paragraph 6.4.2.1 of this Annex. 8. Exceptions8.1. Where a vehicle or electrical/electronic system or ESA does not include an  electronic oscillator with an operating frequency greater than 9 kHz, it shall be deemed to comply  with paragraph 6.3.2 or 6.6.2 of Annex I and with Annexes V and VIII. 8.2. Vehicles which do not have electrical/electronic systems or ESAs involved in the direct  control of the vehicle need not be tested for immunity and shall be deemed to comply with paragraph  6.4 of Annex I and with Annex VI to this Directive. 8.3. ESAs whose functions are not involved in the direct control of the vehicle need not be tested  for immunity and shall be deemed to comply with paragraph 6.7 of Annex I and with Annex IX to this  Directive. 8.4. Electrostatic dischargeFor vehicles fitted with tyres, the vehicle body/chassis can be  considered to be an electrically isolated structure. Significant electrostatic forces in relation  to the vehicle's external environment only occur at the moment of occupant entry into or exit from  the vehicle. As the vehicle is stationary at these moments, no type-approval test for electrostatic  discharge is deemed necessary. 8.5. Conducted transientsSince during normal driving, no external electrical connections are made  to vehicles, no conducted transients are generated in relation to the external environment. The  responsibility of ensuring that equipment can tolerate the conducted transients within a vehicle,  e.g. due to load switching and interaction between systems, lies with the manufacturer. No  type-approval test for conducted transients is deemed necessary.

The test method described in this Annex shall only be applied to  vehicles. 1.2. Measuring apparatusThe measuring equipment shall comply with the requirements of publication  No 16-1 (93) of the International Special Committee on Radio Interference (CISPR). A quasi-peak detector shall be used for the measurement of braodband electromagnetic emissions in  this Annex, or if a peak detector is used an appropriate correction factor shall be used depending  on the spark pulse rate. 1.3. Test methodThis test is intended to measure the broadband emissions generated by spark  ignition systems. Two alternative reference antenna distances are permissible: 10 or 3 m from the vehicle. In either  case the requirements of paragraph 3 of this Annex shall be complied with. 2. Expression of resultsThe results of measurements shall be expressed in dB microvolt/m  (microvol/m) for 120 kHz band width. If the actual band width B (expressed in kHz) of the measuring  apparatus differs from 120 kHz, the readings taken in microvolts/m shall be converted to 120 kHz  band width through multiplication by a factor 120/B. 3. Measuring location3.1. The test site shall be a level, clear area free from electromagnetic  reflecting surfaces within a circle of minimum radius 30 m measured from a point midway between the  vehicle and the antenna (see Figure 1 of Appendix 1 to this Annex). 3.2. The measuring set, test hut, or vehicle in which the measurement set is located may be within  the test site, but only in the permitted region shown in Figure 1 in Appendix 1 to this Annex. Other measuring antennae are allowed within the test area, at a minimum distance of 10 m both from  receiving antenna and the vehicle under test, provided that it can be shown that the test results  will not be affected. 3.3. Enclosed test facilities may be used if correlation can be shown between the enclosed test  facility and an outdoor site. Enclosed test facilities do not need to meet the dimensional  requirements of Figure 1 in Appendix 1 of this Annex other than the distance from the antenna to  the vehicle and the height of the antenna. Neither do they need to have ambient emissions checked  before or after the test as indicated in paragraph 3.4 of this Annex. 3.4. AmbientTo ensure that there is no extraneous noise or signal of a magnitude sufficient to  affect materially the measurement, measurements shall be taken before and after the main test. If  the vehicle is present when ambient measurements are taken, it will be necessary to ensure that any  emissions from the vehicle do not affect significantly the ambient measurements, for example by  removing the vehicle from the test area, removing the ignition key, or disconnecting the battery.  In both of the measurements, the extraneous noise or signal shall be at least 10 dB below the  limits of interference given in paragraph 6.2.2.1 or 6.2.2.2 (as appropriate) of Annex I, except  for intentional narrowband ambient transmissions. 4. Vehicle state during tests4.1. EngineThe engine shall be running at its normal operating  temperature and the transmission shall be in neutral. If for practical reasons this cannot be  achieved, alternative arrangements mutually agreed between the manufacturer and the test  authorities may be made. Care shall be taken to ensure that the speed setting mechanism does not  influence electromagnetic radiations. During each measurement, the engine shall be operated as  follows: >TABLE>4.2. Testing shall not be conducted while rain or other precipitation is falling  on the vehicle or within 10 minutes after such precipitation has stopped. 5. Antenna type, position and orientation5.1. Antenna typeAny antenna may be used provided it can  be normalized to the reference antenna. The method described in CISPR publication No 12, Edition 3,  Appendix A, may be used to calibrate the antenna. 5.2. Height and distance of measurement5.2.1. Height5.2.1.1. 10 m testThe phase centre of the  antenna shall be 3,00 ± 0,05 m above the plane on which the vehicle rests. 5.2.1.2. 3 m testThe phase centre of the antenna shall be 1,80 ± 0,05 m above the plane on which  the vehicle rests. 5.2.1.3. No part of any antenna's receiving elements shall be closer than 0,25 m to the plane on  which the vehicle rests. 5.2.2. Distance of measurement5.2.2.1. 10 m testThe horizontal distance from the tip or other  appropriate point of the antenna defined during the normalization procedure described in paragraph  5.1 to this Annex to the outer body surface of the vehicle shall be 10,0 ± 0,2 m. 5.2.2.2. 3 m testThe horizontal distance from the tip or other appropriate point of the antenna  defined during the normalization procedure described in paragraph 5.1 to this Annex to the outer  body surface of the vehicle shall be 3,00 ± 0,05 m. 5.2.2.3. If the test is carried out in a facility enclosed for radio frequency electromagnetic  screening purposes, the antenna's receiving elements shall be no closer than 1,0 m to any radio  absorbent material and no closer than 1,5 m to the wall of the enclosed facility. There must be no  absorbent material between the receiving antenna and vehicle under test. 5.3. Antenna location relative to vehicleThe antenna shall be located successively on the left and  right-hand sides of the vehicle, with the antenna parallel to the plane of longitudinal symmetry of  the vehicle and in line with the engine mid-point (see Figure 1 in Appendix 1 to this Annex). 5.4. Antenna positionAt each of the measuring points, readings shall be taken both with the  antenna in a horizontal and in a vertical polarization (see Figure 2 in Appendix 1 to this Annex). 5.5. ReadingsThe maximum of the four readings taken in accordance with paragraphs 5.3 and 5.4 at  each spot frequency shall be taken as the characteristic reading at the frequency at which the  measurements were made. 6. Frequencies6.1. MeasurementsMeasurements shall be made throughout the 30 to 1 000 MHz  frequency range. To confirm that the vehicle meets the requirements of this Annex, the Testing  Authority shall test at up to 13 frequencies in the range, e.g. 45, 65, 90, 120, 150, 190, 230,  280, 380, 450, 600, 750, 900 MHz. In the event that the limit is exceeded during the test,  investigations shall be made to ensure that this is due to the vehicle and not to background  radiation. 6.1.1. The limits apply throughout the frequency range 30 to 1 000 MHz. 6.1.2. Measurements can be performed with either quasi-peak or peak detectors. The limits given in  Annex I, paragraphs 6.2 and 6.5 are for quasi-peak. If peak is used, add 38 dB for 1 MHz bandwith  or subtract 22 dB for 1 kHz band width. 6.2. Tolerances>TABLE>The tolerances apply to frequencies quoted and are intended to  avoid interference from transmissions operating on or near the nominal spot frequencies during the  time of measurement.

General1.1. The test method described in this Annex shall only be applied to  vehicles. 1.2. Measuring apparatusThe measuring equipment shall comply with the requirements of publication  No 16-1 (93), of the International Special Committee on Radio Interference (CISPR). An average detector or a peak detector shall be used for the measurement of radiated narrowband  electromagnetic emissions in this Annex. 1.3. Test method1.3.1. This test is intended to measure narrowband electromagnetic emissions such  as might emanate from a microprocessor-based system or other narrowband source. 1.3.2. As an initial step the levels of emissions in the FM frequency band (88 to 108 MHz) shall be  measured at the vehicle broadcast radio antenna with equipment as specified in paragraph 1.2. If  the level specified in paragraph 6.3.2.4 of Annex I is not exceeded, then the vehicle shall be  deemed to comply with the requirements of this Annex in respect of that frequency band and the full  test shall not be carried out. 1.3.3. In the full test procedure two alternative antenna distances are permissible: 10 or 3 m from  the vehicle. In either case the requirements of paragraph 3 of this Annex shall be complied with. 2. Expression of resultsThe results of measurements shall be expressed in dB microvolts/m  (microvolts/m). 3. Measuring location3.1. The test site shall be a level, clear area free from electromagnetic  reflecting surfaces within a circle of minimum radius 30 m measured from a point midway between the  vehicle and the antenna (see Figure 1 of Appendix 1 to Annex IV). 3.2. The measuring set, test hut, or vehicle in which the measurement set is located may be within  the test site, but only in the permitted region shown in Figure 1 of Appendix 1 to Annex IV. Other measuring antennae are allowed within the test area, at a minimum distance of 10 m both from  receiving antenna and the vehicle/STU under test, provided that it can be shown that the test  results will not be affected. 3.3. Enclosed test facilities may be used if correlation can be shown between the enclosed test  facility and an outdoor site. Enclosed test facilities do not need to meet the dimensional  requirements of Figure 1 in Appendix 1 of Annex IV other than the distance from the antenna to the  vehicle and the height of the antenna. Neither do they need to have ambient emissions checked  before or after the test as indicated in paragraph 3.4 of this Annex. 3.4. AmbientTo ensure that there is no extraneous noise or signal of a magnitude sufficient to  affect materially the measurement, ambient measurements shall be taken before and after the main  test. It will be necessary to ensure that any emissions from the vehicle do not affect  significantly the ambient measurements, for example by removing the vehicle from the test area,  removing the ignition key, or disconnecting the battery(ies). In both of the measurements, the  extraneous noise or signal shall be at least 10 dB below the limits of interference given in  paragraph 6.3.2.1 or 6.3.2.2 (as appropriate) of Annex I, except for intentional narrowband ambient  transmissions. 4. Vehicle state during tests4.1. The vehicle's electronic systems shall all be in normal  operating mode with the vehicle stationary. 4.2. The ignition shall be switched on. The engine shall not be operating. 4.3. Measurements shall not be made while rain or other precipitation is falling on the vehicle or  within 10 minutes after such precipitation has stopped. 5. Antenna type, position and orientation5.1. Antenna typeAny antenna may be used provided that  it can be normalized to the reference antenna.

There must be no  absorbent material between the receiving antenna and vehicle under test. 5.3. Antenna location relative to vehicleThe antenna shall be located successively on the left and  right-hand sides of the vehicle with the antenna parallel to the plane of longitudinal symmetry of  the vehicle and in line with the engine mid-point (see Figure 2 in Appendix 1 to Annex IV). 5.4. Antenna positionAt each of the measuring points, readings shall be taken both with the  antenna in a horizontal and in a vertical polarization (see Figure 2 in Appendix 1 to Annex IV). 5.5. ReadingsThe maximum of the four readings taken in accordance with paragraphs 5.3 and 5.4 at  each spot frequency shall be taken as the characteristic reading at the frequency at which the  measurements are made. 6. Frequencies6.1. MeasurementsMeasurements shall be made throughout the 30 to 1 000 MHz  frequency range. This range shall be divided into 13 bands. In each band one spot frequency may be  tested to demonstrate that the required limits are satisfied. To confirm that the vehicle meets the  requirements of this Annex, the testing authority shall test at one such point in each of the  following 13 frequency bands: 30 to 50, 50 to 75, 75 to 100, 100 to 130, 130 to 165, 165 to 200, 200 to 250, 250 to 320, 320 to  400, 400 to 520, 520 to 660, 660 to 820, 820 to 1 000 MHz. In the event that the limit is exceeded during the test, investigations shall be made to ensure  that this is due to the vehicle and not to background radiation. ANNEX VI METHOD OF TESTING FOR IMMUNITY OF VEHICLES TO ELECTROMAGNETIC RADIATION 1.  General1.1. The test method described in this Annex shall only be applied to vehicles. 1.2. Test methodThis test is intended to demonstrate the immunity to degradation in the direct  control of the vehicle. The vehicle shall be subject to electromagnetic fields as described in this  Annex. The vehicle shall be mnitored during the tests. 2. Expression of resultsFor the test described in this Annex, field strengths shall be expressed  in volts/m. 3. Measuring locationThe test facility shall be capable of generating the field strengths over the  frequency ranges defined in this Annex. The test facility shall comply with (national) legal  requirements regarding the emission of electromagnetic signals. Care shall be taken so that the control and monitoring equipment shall not be affected by radiated  fields in such a way as to invalidate the tests. 4. Vehicle state during tests4.1. The vehicle shall be in an unladen condition except for  necessary test equipment. 4.1.1. The engine shall normally turn the driving wheels at a steady speed of 50 km/h if there is  no technical reason for a manufacturer to prefer a different speed. The vehicle shall be on an  appropriately loaded dynamometer or alternatively supported on insulated axle stands with minimum  ground clearance if no dynamometer is available. Where appropriate, transmission shafts may be  disconnected (e.g. trucks). 4.1.2. Headlamps shall be on dipped beam. 4.1.3. Left or right direction indicator shall be operating. 4.1.4. All other systems which affect the driver's control of the vehicle shall be (on) as in  normal operation of the vehicle. 4.1.5. The vehicle shall not be electrically connected to the test area and no connections shall be  made to the vehicle from any equipment, except as required by paragraph 4.1.1 or 4.2. Tyre contact  with the test area floor shall not be considered to be an electrical connection. 4.2. If there are vehicle electrical/electronic systems which form an integral part of the direct  control of the vehicle, which will not operate under the conditions described in paragraph 4.1, it  will be permissible for the manufacturer to provide a report or additional evidence to the testing  authority that the vehicle electrical/electronic system meets the requirements of this Directive.  Such evidence shall be retained in the type-approval documentation. 4.3. Only non-perturbing equipment shall be used while monitoring the vehicle. The vehicle exterior  and the passenger compartment shall be monitored to determine whether the requirements of this  Annex are met (e.g. by using (a) video camera(s)). 4.4. The vehicle shall normally face a fixed antenna. However, where the electronic control units  and the associated wiring harness are predominantly in the rear of the vehicle, the test should  normally be carried out with the vehicle facing away from the antenna. In the case of long vehicles  (i.e. excluding cars and light vans), which have electronic control units and associated wiring  harness predominantly towards the middle of the vehicle, a reference point (see paragraph 5.4 of  this Annex) may be established based on either the right side surface or the left side surface of  the vehicle. This reference point shall be at the midpoint of the vehicle's length or at one point  along the side of the vehicle chosen by the manufacturer in conjunction with the competent  authority after considering the distribution of electronic systems and the layout of any wiring  harness. Such testing may only take place if the physical construction of the chamber permits. The antenna  location must be noted in the test report. 5. Field generating device type, position and orientation5.1. Field generating device type5.1.1.  The field generating device type(s) shall be chosen such that the desired field strength is  achieved at the reference point (see paragraph 5.4 of this Annex) at the appropriate frequencies. 5.1.2.

No part of any antenna's radiating elements shall be closer than 0,25 m to the plane on  which the vehicle rests. 5.2.2. Distance of measurement5.2.2.1. In-service conditions may be best approximated by placing  the field generating device as far from the vehicle as practical. This distance will typically lie  within the range 1 to 5 m. 5.2.2.2. If the test is carried out in an enclosed facility, the field generating device's  radiating elements shall be no closer than 1,0 m to any radio absorbent material and no closer than  1,5 m to the wall of the enclosed facility. There shall be no absorbent material between the  transmitting antenna and the vehicle under test. 5.3. Antenna location relative to vehicle5.3.1. The field generating device's radiating elements  shall not be closer than 0,5 m to the outer body surface of the vehicle. 5.3.2.

No part of a TLS, with the exception of the plane on which the vehicle rests, shall be  closer than 0,5 m to any part of the vehicle. 5.3.4. Any field generating device which is placed over the vehicle shall extend centrally over at  least 75 % of the length of the vehicle. 5.4. Reference point5.4.1.

If it is decided to radiate the rear of the vehicle, the reference point shall be established  as in paragraph 5.4. The vehicle shall then be installed facing away from the antenna and  positioned as if it had been horizontally rotated 180° around its centre point, i.e. such that the  distance from the antenna to the nearest part of the outer body of the vehicle remains the same.  This is illustrated in Appendix 3 to this Annex. 6. Test requirements6.1.

To take account of different vehicle geometries, a number of antennae positions or reference  points may need to be established for a given test facility. 7.2. Field strengh contour7.2.1. During the calibration phase of the substitution method (prior to  a vehicle being introduced into the test area), the field strength in at least 80 % of the  calibration steps shall not be less than 50 % of the nominal field strength, at the following  locations: (a) for all field generating devices, 0,5 ± 0,05 m either side of the reference point on a line  passing through the reference point and at the same height as the reference point, and  perpendicular to the vehicle plane of longitudinal symmetry; (b) in the case of a TGLS, 1,50 ± 0,05 m on a line passing through the reference point at the same  height as the reference point and along the line of longitudinal symmetry. 7.3.

Alternatively, the fully extended length of the wiring harness, including the length of  the longest of any branches, shall be 1,5 m. 7.3.2. 800 mm stripline testing7.3.2.1. Test methodThe stripline consists of two parallel  metallic plates separated by 800 mm. Equipment under test is positioned centrally between the  plates and subjected to an electromagnetic field (see Figures 3 and 4 of Appendix 1 to this  Annex). This method can test complete electronic systems including sensors and actuators as well as the  controller and wiring loom. It is suitable for apparatus whose largest dimension is less than  one-third of the plate separation. 7.3.2.2. Positioning of striplineThe stripline shall be housed in a screened room (to prevent  external emissions) and positioned 2 m away from walls and any metallic enclosure to prevent  electromagnetic reflections. RF absorber material may be used to damp these reflections. The  stripline shall be placed on non-conducting supports at least 0,4 m above the floor. 7.3.2.3. Calibration of the striplineA field measuring probe shall be positioned within the  central one-third of the longitudinal, vertical and transverse dimensions of the space between the  parallel plates with the system under test absent. The associated measuring equipment shall be  sited outside the screen room. At each desired test frequency, a level of power shall be fed into the stripline to produce the  required field strength at the antenna. This level of forward power, or another parameter directly  related to the forward power required to define the field, shall be used for type approval tests  unless changes occur in the facilities or equipment which necessitate this procedure being  repeated. 7.3.2.4. Installation of the ESA under testThe main control unit shall be positioned within the  central one-third of the longitudinal, vertical and transverse dimensions of the space between the  parallel plates. It shall be supported on a stand made from non-conducting material. 7.3.2.5. Main wiring loom and sensor/actuator cablesThe main wiring loom and any sensor/actuator  cables shall rise vertically from the control unit to the top ground plate (this helps to maximise  coupling with the electromagnetic field). Then they shall follow the underside of the plate to one  of its free edges where they shall loop over and follow the top of the ground plate as far as the  connections to the stripline feed. The cables shall then be routed to the associated equipment  which shall be sited in an area outside the influence of the electromagnetic field, e.g.: on the  floor of the screened room 1 m longitudinally away from the stripline. 8. Free field ESA immunity test8.1. Test methodThis test method allows the testing of vehicle  electrical/electronic systems by exposing an ESA to electromagnetic radiation generated by an  antenna. 8.2. Test bench descriptionThe test shall be performed inside a semi-anechoic chamber on a bench  top. 8.2.1. Ground plane8.2.1.1. For free field immunity testing, the ESA under test and its wiring  harnesses shall be supported 50 ± 5 mm above a wooden or equivalent non-conducting table. However,  if any part of the ESA under test is intended to be electrically bonded to a vehicle's metal  bodywork, that part shall be placed on a ground plane and shall be electrically bonded to the  ground plane. The ground plane shall be a metallic sheet with a minimum thickness of 0,5 mm. The  minimum size of the ground plane depends on the size of the ESA under test but shall allow for the  distribution of the ESA's wiring harness and components. The ground plane shall be connected to the  protective conductor of the earthing system. The ground plane shall be situated at a height of 1,0  ± 0,1 m above the test facility floor and shall be parallel to it. 8.2.1.2. The ESA under test shall be arranged and connected according to its requirements. The  power supply harness shall be positioned along, and within 100 mm of, the edge of the ground  plane/table closest to the antenna. 8.2.1.3. The ESA under test shall be connected to the grounding system according to the  manufacturer's installation specification, no additional grounding connections shall be permitted. 8.2.1.4. The minimum distance between the ESA under test and all other conductive structures, such  as walls of a shielded area (with the exception of the ground plane/table underneath the test  object) must be 1,0 m. 8.2.1.5. The dimension of any ground plane shall be 2,25 square meter or larger in area with the  smaller side no less than 750 mm. The ground plane shall be bonded to the chamber with bonding  straps such that the DC bonding resistance shall not exceed 2,5 milliohms. 8.2.2. Installation of ESA under testFor large equipment mounted on a metal test stand, the test  stand shall be considered a part of the ground plane for testing purposes and shall be bonded  accordingly. The faces of the test sample shall be located at a minimum of 200 mm from the edge of  the ground plane. All leads and cables shall be a minimum of 100 mm from the edge of the ground  plane and the distance to the ground plane (from the lowest point of the harness) shall be 50 ± 5  mm above the ground plane. Power shall be applied to the ESA under test via an (5 µ H/50  `)  artificial network (AN). 8.3. Field generating device type, position and orientation8.3.1. Field generating device  type8.3.1.1. The field generating device type(s) shall be chosen such that the desired field  strength is achieved at the reference point (see paragraph 8.3.4 of this Annex) at the appropriate  frequencies. 8.3.1.2. The field generating device(s) may be (an) antenna(s) or a plate antenna. 8.3.1.3. The construction and orientation of any field generating device shall be such that the  generated field is polarised: from 20 to 1 000 MHz horizontally or vertically. 8.3.2. Height and distance of measurement8.3.2.1. HeightThe phase centre of any antenna shall be  150 ± 10 mm above the ground plane on which the ESA under test rests. No parts of any antenna's  radiating elements shall be closer than 250 mm to the floor of the facility. 8.3.2.2. Distance of measurement8.3.2.2.1. In-service conditions may best be approximated by  placing the field generating device as far from the ESA as practical. This distance will typically  lie within the range 1 to 5 m. 8.3.2.2.2. If the test is carried out in an enclosed facility, the field generating device's  radiating elements shall be no closer than 0,5 m to any radio absorbent material and no closer than  1,5 m to the wall of the facility. There shall be no absorbent material interposed between the  transmitting antenna and the ESA under test. 8.3.3. Antenna location relative to ESA under test8.3.3.1. The field generating device's radiating  elements shall not be closer than 0,5 m to the edge of the ground plane. 8.3.3.2. The phase centre of the field generating device shall be on a plane which: (a) is perpendicular to the ground plane; (b) bisects the edge of the ground plane and the midpoint of the principal portion of the wiring  harness; and(c) is perpendicular to the edge of the ground plane and the principal portion of the wiring  harness. The field generating device shall be placed parallel to this plane (see Figures 1 and 2 of Appendix  4 to this Annex). 8.3.3.3. Any field generating device which is placed over the ground plane or ESA under test shall  extend over the ESA under test. 8.3.4. Reference pointFor the purpose of this Annex the reference point is the point at which the  field strength shall be established and shall be defined as follows: 8.3.4.1. at least 1 m horizontally from the antenna phase centre or at least 1 m vertically from  the radiating elements of a plate antenna; 8.3.4.2. on a plane which: (a) is perpendicular to the ground plane; (b) is perpendicular to the edge of the ground plane along which the principal portion of the  wiring harness runs; and(c) bisects the edge of the ground plane and the midpoint of the principal portion of the  wiring harness; (d) coincident with the midpoint of the principal portion of the harness which runs along the edge  of the ground plane closest to the antenna; 8.3.4.3. 150 ± 10 mm above the ground plane. 8.4. Generation of required field strength: test methodology8.4.1. the 'substitution method' shall  be used to establish the test field conditions. 8.4.2. Substitution methodAt each desired test frequency, a level of power shall be fed into the  field generating device to produce the required field strength at the reference point (as defined  in paragraph 8.3.4 in the test area with the ESA under test absent), this level of forward power,  or another parameter directly related to the forward power required to define the field, shall be  measured and the results recorded. These results shall be used for type approval tests unless  changes occur in the facilities or equipment which necessitates this procedure being repeated. 8.4.3. Extraneous equipment must be a minimum of 1 m from the reference point during calibration. 8.4.4. Field strength measuring deviceA suitable compact field strength measuring device shall be  used to determine the field strength during the calibration phase of the substitution method. 8.4.5. The phase centre of the field strength measuring device shall be positioned at the reference  point. 8.4.6. The ESA under test which may include an additional ground plane shall then be introduced  into the test facility and positioned in accordance with the requirements of paragraph 8.3. If a  second ground plane is used, then it shall be within 5 mm of the bench ground plane and  electrically bounded to it. The required forward power defined in paragraph 8.4.2 at each frequency  as defined in paragraph 5 shall then be applied to the field generating device. 8.4.7. Whatever parameter was chosen in paragraph 8.4.2 to define the field, the same parameter  shall be used to determine the field strength during the test. 8.5. Field strength contour8.5.1. During the calibration phase of the substitution method (prior  to an ESA under test being introduced into the test area), the field strength shall not be less  than 50 % of the nominal field strength 0,5 ± 0,05 m either side of the reference point on a line  parallel to the edge of the ground plane nearest to the antenna and passing through the reference  point. 9. TEM cell testing9.1. Test methodThe TEM (transverse electromagnetic mode) cell generates  homogeneous fields between the internal conductor (septum) and housing (ground plane). It is used  for testing ESAs (see Figure 1 of Appendix 3 to this Annex)). 9.2. Field strength measurement in a TEM cell9.2.1. The electric field in the TEM cell shall be  determined by using the equation: >START OF GRAPHIC>|E| = &radic;(P × Z) d>END OF GRAPHIC>E = Electric field (volts/metre)P =  Power flowing into cell (W)Z = Impedance of cell (50  `)d = Separation distance (metres) between  the upper wall and the plate (septum). 9.2.2. Alternatively an appropriate field strength sensor shall be placed in the upper half of the  TEM cell. In this part of the TEM cell the electronic control unit(s) has only a small influence on  the test field. The output of this sensor shall determine the field strength. 9.3. Dimensions of TEM cellIn order to maintain a homogeneous field in the TEM cell and to obtain  repeatable measurement results, the test object shall not be larger than one-third of the cell  inside height. Recommended TEM cell dimensions are given in Appendix 3, Figures 2 and 3 to this  Annex. 9.4. Power, signal and control wiresThe TEM cell shall be attached to a co-axial socket panel and  connected as closely as possible to a plug connector with an adequate number of pins. The supply  and signal leads from the plug connector in the cell wall shall be directly connected to the test  object. The external components such as sensors, power supply and control elements can be connected: (a) to a screened peripheral; (b) to a vehicle next to the TEM cell; or(c) directly to the screened patchboard. Screened cables must be used in connecting the TEM cell to the peripheral or the vehicle if the  vehicle or peripheral is not in the same or adjacent screened room. 10. Bulk current injection testing10.1. Test methodThis is a method of carrying out immunity  tests by inducing currents directly into a wiring harness using a current injection probe. The  injection probe consists of a coupling clamp through which the cables of the ESA under test are  passed. Immunity tests can then be carried out by varying the frequency of the induced signals. The ESA under test may be installed on a ground plane as in paragraph 8.2.1 or in a vehicle in  accordance with the vehicle design specification. 10.2. Calibration of bulk current injection probe prior to commencing testsThe injection probe  shall be mounted in a calibration jig. Whilst sweeping the test frequency range, the power required  to achieve the current specified in Annex I, paragraph 6.7.2.1 shall be monitored. This method  calibrates the bulk current injection system forward power versus current prior to testing, and it  is this forward power which shall be applied to the injection probe when connected to the ESA under  test via the cables used during calibration. It should be noted that the monitored power applied to  the injection probe is the forward power. 10.3. Installation of the ESA under testFor an ESA mounted on a ground plane as in paragraph 8.2.1  all cables in the wiring harness should be terminated as realistically as possible and preferably  with real loads and actuators. For both vehicle mounted and ground plane mounted ESAs the current  injection probe shall be mounted in turn around all the wires in the wiring harness to each  connector and 150 ± 10mm from each connector of the ESA under test electronic control units (ECU),  instrument modules or active sensors as illustrated in Figure 1 of Appendix 2. 10.4. Power, signal and control wiresFor an ESA under test mounted on a ground plane as in  paragraph 8.2.1, a wiring harness shall be connected between an artificial network (AN) and the  principal electronic control unit (ECU). This harness shall run parallel to the edge of the ground  plane and 200 mm minimum from its edge. This harness shall contain the power feed wire which is  used to connect the vehicle battery to this ECU and the power return wire if used on the vehicle. The distance from the ECU to the AN shall be 1,0 ± 0,1 m or shall be the harness length between the  ECU and the battery as used on the vehicle, if known, whichever is the shorter. If a vehicle  harness is used then any line branches which occur in this length shall be routed along the ground  plane but perpendicular away from the edge of the ground plane. Otherwise the ESA under test wires  which are in this length shall break out at the AN.
