of 13 July 2009
         
on the suppression of radio interference produced by agricultural or forestry tractors (electromagnetic compatibility)
(codified version)
(Text with EEA relevance)


THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Article 95 thereof,


Having regard to the proposal from the Commission,


Having regard to the opinion of the European Economic and Social Committee (1),


Acting in accordance with the procedure laid down in Article 251 of the Treaty (2),

Whereas:







(1)


Council Directive 75/322/EEC of 20 May 1975 on the suppression of radio interference produced by agricultural or forestry tractors (electromagnetic compatibility) (3) has been substantially amended several times (4). In the interests of clarity and rationality the said Directive should be codified.












(2)


Directive 75/322/EEC is one of the separate Directives of the EC type-approval system provided for in Council Directive 74/150/EEC of 4 March 1974 on the approximation of the laws of the Member States relating to the type-approval of wheeled agricultural or forestry tractors, as replaced by Directive 2003/37/EC of the European Parliament and of the Council of 26 May 2003 on type-approval of agricultural or forestry tractors, their trailers and interchangeable towed machinery, together with their systems, components and separate technical units (5), and lays down technical prescriptions concerning the suppression of radio interference produced by agricultural or forestry tractors (electromagnetic compatibility). Those technical prescriptions concern the approximation of the laws of the Member States to enable the EC type-approval procedure provided for in Directive 2003/37/EC to be applied in respect of each type of tractor. Consequently, the provisions laid down in Directive 2003/37/EC relating to agricultural and forestry tractors, their trailers and interchangeable towed machinery, together with their systems, components and separate technical units apply to this Directive.

ANNEX I
REQUIREMENTS TO BE MET BY VEHICLES AND ELECTRICAL/ELECTRONIC SUB-ASSEMBLIES FITTED TO A VEHICLE
1.   SCOPE
1.1.   This Directive applies to the electromagnetic compatibility of vehicles covered by Article 1. It also applies to electrical or electronic separate technical units intended to be fitted to the vehicles.
2.   DEFINITIONS
2.1.   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 specialised functions. An ESA may be approved at the request of a manufacturer as either a ‘component’ or a ‘separate technical unit (STU)’ (see Article 4(1)(c) of Directive 2003/37/EC).

                     ‘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.
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 EC TYPE-APPROVAL
3.1.   Approval of a vehicle type
3.1.1.   The application for approval of a vehicle type, with regard to its electromagnetic compatibility pursuant to Article 4(1) of Directive 2003/37/EC shall be submitted by the vehicle manufacturer.
3.1.2.   A model for the information document is set out in Annex II.
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 point 6.4.2.3) 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 of Annex II). 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 point 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 EC 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 point 3.1.4 shall be provided.
3.2.   Approval of a type of ESA
3.2.1.   The application for approval of a type of ESA with regard to its electromagnetic compatibility pursuant to Article 4(1) of Directive 2003/37/EC shall be submitted by the vehicle manufacturer or by the manufacturer of the ESA.
3.2.2.   A model for the information document is set out in Annex III.
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 EC 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, the number of components and the 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 shall be identified. Any such restrictions shall be included in the information document set out in Annex III and/or in the EC type-approval certificate set out in Annex V.
4.   TYPE-APPROVAL
4.1.   Routes to type-approval
4.1.1.   Type-approval of a vehicle
The 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 installation
A vehicle installation may achieve type-approval directly by following the provisions laid down in point 6. 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 ESAs
A vehicle manufacturer may obtain approval for the vehicle by demonstrating to the approval authority that all the relevant (see point 3.1.3) 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 pursuant 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 point 3.1.3 (immunity) and no spark ignition equipment. Such approvals shall not require testing.
4.1.2.   Type-approval of an ESA
Type-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-approval
4.2.1.   Vehicle
4.2.1.1.   If the representative vehicle fulfils the requirements of this Directive, EC type-approval pursuant to Article 4 of Directive 2003/37/EC shall be granted.
4.2.1.2.   A model for the EC type-approval certificate is set out in Annex IV.
4.2.2.   ESA
4.2.2.1.   If the representative ESA system(s) fulfil(s) the requirements of this Directive, EC type-approval pursuant to Article 4 of Directive 2003/37/EC shall be granted.
4.2.2.2.   A model for the EC type-approval certificate is given in Annex V.
4.2.3.   In order to draw up the certificates referred to in point 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 recognised laboratory or in accordance with the provisions of this Directive.
4.3.   Amendments to approvals
4.3.1.   In the case of amendments to approvals granted pursuant to this Directive, the provisions of Article 5(2) and (3) of Directive 2003/37/EC 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 point 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 (2) which complies with Directive 2004/108/EC, 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 may 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, namely excluding transmission in conjunction with the tests specified in point 6. This Directive does not authorise 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 2004/108/EC.
5.   MARKING
5.1.   Every ESA conforming to a type approved pursuant to this Directive shall bear an EC type-approval mark.
5.2.   This mark shall consist of a rectangle surrounding the letter ‘e’ followed by the distinguishing number of the Member State which has granted EC type-approval:
1 for Germany; 2 for France; 3 for Italy; 4 for the Netherlands; 5 for Sweden; 6 for Belgium; 7 for Hungary; 8 for the Czech Republic; 9 for Spain; 11 for the United Kingdom; 12 for Austria; 13 for Luxembourg; 17 for Finland; 18 for Denmark; 19 for Romania; 20 for Poland; 21 for Portugal; 23 for Greece; 24 for Ireland; 26 for Slovenia; 27 for Slovakia; 29 for Estonia; 32 for Latvia; 34 for Bulgaria; 36 for Lithuania; 49 for Cyprus; 50 for Malta.
It must also include in the vicinity of the rectangle the four-digit sequential number (with leading zeros as applicable) — hereinafter referred to as the ‘base approval number’ — contained in Section 4 of the type-approval number shown on the EC type-approval certificate issued for the type of device in question (see Annex V), preceded by the two figures indicating the sequence number assigned to the most recent major technical amendment to Directive 75/322/EEC, as replaced by this Directive, on the date EC component type-approval was granted.
5.3.   The EC type-approval mark must be affixed to the main part of the ESA (for example the electronic control unit) in such a way as to be clearly legible and indelible.
5.4.   An example of the EC type-approval mark is set out 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 point 5.3 need not be visible when the ESA is installed in a vehicle.

6.6.2.2.   On the ESA representative of its type, the measured value, expressed in dB microvolts/m (microvolts/m) shall be at least 2,0 dB (20 %) below the reference limits.
6.7.   Specifications concerning immunity of ESAs to electromagnetic radiation
6.7.1.   Method(s) of testing
The immunity to electromagnetic radiation of the ESA representative of its type shall be tested by the method(s) chosen from those described in Annex XI.
6.7.2.   ESA immunity reference limits
6.7.2.1.   If tests are made using the methods described in Annex XI, 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 transverse electromagnetic mode (TEM) cell testing method, 48 mA for the bulk current injection (BCI) testing method and 24 volts/m for the free field testing method.

7.   CONFORMITY OF PRODUCTION
7.1.   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 EC type-approval certificate(s) set out in Annex IV and/or Annex V as appropriate.
7.2.   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 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 points 6.2.2.1, 6.2.2.2, 6.3.2.1 and 6.3.2.2 (as appropriate).
7.3.   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 point 4 of Annex VIII and subjected to a field strength, expressed in volts/m, up to 80 % of the reference limits prescribed in point 6.4.2.1 of this Annex.
8.   EXCEPTIONS
8.1.   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 point 6.3.2 or 6.6.2 of this Annex and with Annexes VII and X.
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 point 6.4 of this Annex and with Annex VIII.
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 point 6.7 of this Annex and with Annex XI.
8.4.   Electrostatic discharge
For 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 transients
Since 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, for example due to load switching and interaction between systems, lies with the manufacturer. No type-approval test for conducted transients is deemed necessary.

ANNEX VI
METHOD OF MEASUREMENT OF RADIATED BROADBAND ELECTROMAGNETIC EMISSIONS FROM VEHICLES
1.   GENERAL
1.1.   The test method described in this Annex shall only be applied to vehicles.
1.2.   Measuring apparatus
The 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 broadband 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 method
This test is intended to measure the broadband electromagnetic emissions generated by spark-ignition systems and by electric motors (electric traction motors, engines for heating or de-icing systems, fuel pumps, water pumps, etc.) permanently fitted to the vehicle.
Two alternative reference antenna distances are permissible: 10 or 3 m from the vehicle. In either case the requirements of point 3 shall be complied with.
2.   EXPRESSION OF RESULTS
The results of measurements shall be expressed in dB microvolts/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 LOCATION
3.1.   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 in Appendix 1).
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.
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 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 point 3.4.
3.4.   Ambient
To 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 point 6.2.2.1 or 6.2.2.2 (as appropriate) of Annex I, except for intentional narrowband ambient transmissions.
4.   VEHICLE STATE DURING TESTS
4.1.   Engine
The 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:







Engine type


Method of measurements




Quasi peak


Peak




Spark ignition


Engine speed


Engine speed




One cylinder


2 500  rpm ± 10 %


2 500  rpm ± 10 %




More than one cylinder


1 500  rpm ± 10 %


1 500  rpm ± 10 %




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.

ANNEX VII
METHOD OF MEASUREMENT OF RADIATED NARROWBAND ELECTROMAGNETIC EMISSIONS FROM VEHICLES
1.   GENERAL
1.1.   The test method described in this Annex shall only be applied to vehicles.
1.2.   Measuring apparatus
The 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 method
1.3.1.   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 point 1.2. If the level specified in point 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 point 3 of this Annex shall be complied with.
2.   EXPRESSION OF RESULTS
The results of measurements shall be expressed in dB microvolts/m (microvolts/m).
3.   MEASURING LOCATION

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 of Annex VI.
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 Annex VI 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 point 3.4 of this Annex.
3.4.   Ambient
To 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 point 6.3.2.1 or 6.3.2.2 (as appropriate) of Annex I, except for intentional narrowband ambient transmissions.

The 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 of Annex VI).
5.4.   Antenna position
At each of the measuring points, readings shall be taken both with the antenna in a horizontal and in a vertical polarisation (see Figure 2 in Appendix 1 of Annex VI).
5.5.   Readings
The maximum of the four readings taken in accordance with points 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.   FREQUENCIES
6.1.   Measurements
Measurements 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 VIII
METHOD OF TESTING FOR IMMUNITY OF VEHICLES TO ELECTROMAGNETIC RADIATION
1.   GENERAL
1.1.   The test method described in this Annex shall only be applied to vehicles.
1.2.   Test method
This 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 monitored during the tests.
2.   EXPRESSION OF RESULTS
For the test described in this Annex, field strengths shall be expressed in volts/m.
3.   MEASURING LOCATION
The 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 TESTS
The vehicle shall be in an unladen condition except for necessary test equipment.
4.1.1.   The engine shall turn the driving wheels normally at a constant speed corresponding to three quarters of the maximum speed of the vehicle if there is no technical reason for the manufacturer to prefer another speed. The vehicle's engine must be loaded with an appropriate torque. If need be, the transmission shafts may be disengaged (for example, in the case of vehicles with more than two axles), provided they do not drive a component-emitting interference.
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 point 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 point 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 (for example 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 shall normally be carried out with the vehicle facing away from the antenna. In the case of long vehicles (namely 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 point 5.4) 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 ORIENTATION
5.1.   Field generating device type
5.1.1.   The field generating device type(s) shall be chosen such that the desired field strength is achieved at the reference point (see point 5.4) at the appropriate frequencies.
5.1.2.   The field generating device(s) may be an antenna or antennas or a transmission line system (TLS).
5.1.3.   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.
5.2.   Height and distance of measurement
5.2.1.   Height
5.2.1.1.   The phase centre of any antenna shall not be less than 1,5 m above the plane on which the vehicle rests or not less than 2,0 m above the plane on which the vehicle rests if the vehicle roof exceeds 3 m in height.

5.2.2.   Distance of measurement
5.2.2.1.   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.

5.3.3.   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 point
For the purposes of this Annex the reference point is the point at which the field strength shall be established and shall be defined as follows:
5.4.1.1.   at least 2 m horizontally from the antenna phase centre or at least 1 m vertically from the radiating elements of a TLS,
5.4.1.2.   on the vehicle's centre line (plane of longitudinal symmetry),
5.4.1.3.   at a height of 1,0 ± 0,05 m above the plane on which the vehicle rests or 2,0 ± 0,05 m if the minimum height of the roof of any vehicle in the model range exceeds 3,0 m,
5.4.1.4.   for front illumination, either:






—


1,0 ± 0,2 m inside the vehicle, measured from the point of intersection of the windscreen and bonnet (point C in Appendix 1), or










—


0,2 ± 0,2 m from the centre line of the front axle of the tractor, measured towards the centre of the tractor (point D in Appendix 2),




whichever results in a reference point closer to the antenna,
5.4.1.5.   for rear illumination, either:






—


1,0 ± 0,2 m inside the vehicle, measured from the point of intersection of the windscreen and bonnet (point C in Appendix 1), or

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, namely in such a way 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.
6.   TEST REQUIREMENTS
6.1.   Frequency range, dwell times, polarisation
The vehicle shall be exposed to electromagnetic radiation in the 20 to 1 000 MHz frequency range.

Test frequencies shall lie in the range 20 to 1 000 MHz. Calibration shall be made, starting at 20, in steps not greater than two per cent of the previous frequency finishing at 1 000 MHz. These results shall be used for type-approval tests unless changes occur in the facilities or equipment which necessitate this procedure being repeated.
7.1.3.   Test phase
The vehicle shall then be introduced into the test facility and positioned in accordance with the requirements of point 5. The required forward power defined in point 7.1.2 at each frequency as defined in point 6.1.1 shall then be applied to the field generating device.
7.1.4.   Whatever parameter was chosen in point 7.1.2 to define the field, the same parameter shall be used to establish the field strength during the test.
7.1.5.   The field generating equipment and its layout employed during the test shall be to the same specification as that used during the operations performed in point 7.1.2.
7.1.6.   Field strength measuring device
A suitable compact field strength measuring device shall be used to determine the field strength during the calibration phase of the substitution method.
7.1.7.   During the calibration phase of the substitution method, the phase centre of the field strength measuring device shall be positioned at the reference point.
7.1.8.   If a calibrated receiving antenna is used as the field strength measuring device, readings shall be obtained in three mutually orthogonal directions and the isotropic equivalent value of the readings shall be taken as the field strength.
7.1.9.   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 strength contour
7.2.1.   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 TLS, 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.

6.   FREQUENCIES
6.1.   Measurements
Measurements shall be made throughout the 30 to 1 000 MHz frequency range. An ESA is considered as very likely to satisfy the required limits over the whole frequency range if it satisfies them at the following 13 frequencies in the range: 45, 65, 90, 120, 150, 190, 230, 280, 380, 450, 600, 750 and 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 ESA 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 points 6.2 and 6.5 of Annex I are for quasi-peak. If peak is used, add 38 dB for 1 MHz band width or subtract 22 dB for 1 kHz band width.

10.   BULK CURRENT INJECTION TESTING
10.1.   Test method
This 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 point 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 tests
The injection probe shall be mounted in a calibration jig. Whilst sweeping the test frequency range, the power required to achieve the current specified in point 6.7.2.1 of Annex I 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 test
For an ESA mounted on a ground plane as in point 8.2.1 all cables in the wiring harness shall 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 Appendix 2.
10.4.   Power, signal and control wires

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.
