ANNEX IV

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.

Test method
This test is intended to measure the broadband emissions generated by electrical or electronic systems fitted to the vehicle (e.g. ignition system or electric motors).
If not otherwise stated in this Annex the test shall be performed according to CISPR 12 (5th edition 2001).
2.

Vehicle state during tests
2.1.

Engine
The engine shall be in operation according to CISPR 12 (5th edition 2001) clause 5.3.2.
2.2.

Other vehicle systems
All equipment capable of generating broadband emissions which can be switched on permanently by the driver or passenger should be in operation in maximum load, e.g. wiper motors or fans. The horn and electric window motors, etc., are excluded because they are not used continuously.
3.

Test requirements
3.1.
The limits apply throughout the frequency range 30 to 1 000 MHz for measurements performed in a semi anechoic chamber or an outdoor test site.
3.2.
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 detectors. If peak detectors are used a correction factor of 20 dB as defined in CISPR 12 (5th edition 2001) shall be applied.
3.3.

Measurements
The technical service shall perform the test at the intervals specified in the CISPR 12 (5th edition 2001) standard throughout the frequency range 30 to 1 000 MHz.
Alternatively, if the manufacturer provides measurement data for the whole frequency band from a test laboratory accredited to the applicable parts of ISO 17025 (1st edition 1999) and recognised by the Approval Authority, the technical service may divide the frequency range in 14 frequency bands 30-34, 34-45, 45-60, 60-80, 80-100, 100-130, 130-170, 170-225, 225-300, 300-400, 400-525, 525-700, 700-850, 850-1 000 MHz and perform tests at the 14 frequencies giving the highest emission levels within each band to confirm that the vehicle meets the requirements of this Annex.
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.
3.4.

Readings
The maximum of the readings relative to the limit (horizontal and vertical polarisation and antenna location on the left and right-hand sides of the vehicle) in each of the 14 frequency bands shall be taken as the characteristic reading at the frequency at which the measurements were made.
ANNEX V

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.

Test method
This test is intended to measure the narrowband electromagnetic emissions such as might emanate from microprocessor-based systems or other narrowband source.
If not otherwise stated in this Annex the test shall be performed according to CISPR 12 (5th edition 2001) or to CISPR 25 (2nd edition 2002).
1.3

As an initial step the levels of emissions in the FM frequency band (76 o 108 MHz) shall be measured at the vehicle broadcast radio antenna with an average detector. 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.
2.

Vehicle state during tests
2.1.
The ignition switch shall be switched on. The engine shall not be operating.
2.2.
The vehicle's electronic systems shall all be in normal operating mode with the vehicle stationary.
2.3.
All equipment which can be switched on permanently by the driver or passenger with internal oscillators > 9 kHz or repetitive signals should be in normal operation.
3.

Test requirements
3.1.
The limits apply throughout the frequency range 30 to 1 000 MHz for measurements performed in a semi anechoic chamber or an outdoor test site.
3.2.
Measurements shall be performed with an average detector.
3.3.

Measurements
The technical service shall perform the test at the intervals specified in the CISPR 12 (5th edition 2001) standard throughout the frequency range 30 to 1 000 MHz.
Alternatively, if the manufacturer provides measurement data for the whole frequency band from a test laboratory accredited to the applicable parts of ISO 17025 (1st edition 1999) and recognised by the Approval Authority, the technical service may divide the frequency range in 14 frequency bands 30-34, 34-45, 45-60, 60-80, 80-100, 100-130, 130-170, 170-225, 225-300, 300-400, 400-525, 525-700, 700-850, 850-1 000 MHz and perform tests at the 14 frequencies giving the highest emission levels within each band to confirm that the vehicle meets the requirements of this Annex.
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 including broadband radiation from any ESA.
3.4.

Readings
The maximum of the readings relative to the limit (horizontal and vertical polarisation and antenna location on the left and right-hand sides of the vehicle) in each of the 14 frequency bands shall be taken as the characteristic reading at the frequency at which the measurements were made.
ANNEX VI

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 of the vehicle electronic systems. The vehicle shall be subject to electromagnetic fields as described in this Annex. The vehicle shall be monitored during the tests.
If not otherwise stated in this Annex, the test shall be performed according to ISO DIS 11451-2:2003.
1.3.

Alternative test methods
The test may be alternatively performed in an outdoor test site for all vehicles. The test facility shall comply with (national) legal requirements regarding the emission of electromagnetic fields.
If a vehicle is longer than 12 m and/or wider than 2,60 m and/or higher than 4,00 m, the BCI method according to ISO 11451-4 (1st edition 1995) can be used in the frequency range 20-2 000 MHz with levels defined in Annex I, paragraph 6.7.2.1.
2.

Vehicle state during tests
2.1.

The vehicle shall be in an unladen condition except for necessary test equipment.
2.1.1.
The engine shall normally turn the driving wheels at a steady speed of 50 km/h if there is no technical reason due to the vehicle to define a different condition. 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).
2.1.2.

Basic vehicle conditions
The paragraph defines minimum test conditions and failures criteria for vehicle immunity tests. Other vehicle systems, which can affect immunity-related functions must be tested in a way to be agreed between manufacturer and technical service.

To be defined in brake cycle test plan. This must include operation of the brake pedal (unless there are technical reasons not to do so) but not necessarily an anti-lock brake system action. | Stop lights inactivated during cycle Brake warning light ON with loss of function Unexpected activation
2.1.3.
All equipment which can be switched on permanently by the driver or passenger should be in normal operation.
2.1.4.
All other systems which affect the driver’s control of the vehicle shall be (on) as in normal operation of the vehicle.
2.2.
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.
2.3.
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), a microphone, etc.).
3.

Test requirements
3.1.

Frequency range, dwell times, polarisation
The vehicle shall be exposed to electromagnetic radiation in the 20 to 2 000 MHz frequency ranges in vertical polarisation.
The test signal modulation shall be:
- AM, with 1 kHz modulation and 80 % modulation depth in the 20-800 MHz frequency range, and
- PM, t on 577 μs, period 4 600 μs in the 800-2 000 MHz frequency range,
if not otherwise agreed between technical service and vehicle manufacturer.
Frequency step size and dwell time shall be chosen according to ISO DIS 11451-1:2003.
3.1.1.
The technical service shall perform the test at the intervals specified in ISO DIS 11451-1:2003 throughout the frequency range 20 to 2 000 MHz.
Alternatively, if the manufacturer provides measurement to data for the whole frequency band from a test laboratory accredited to the applicable parts of ISO 17025 (1st edition 1999) and recognised by the Approval Authority, the technical service may choose a reduced number of spot frequencies in the range, e.g. 27, 45, 65, 90, 120, 150, 190, 230, 280, 380, 450, 600, 750, 900, 1 300, and 1 800 MHz to confirm that the vehicle meets the requirements of this Annex.
If a vehicle fails the test defined in this Annex, it must be verified as having failed under the relevant test conditions and not as a result of the generation of uncontrolled fields.
4.

Generation of required field strength
4.1.

Test methodology
4.1.1.
The substitution method according to ISO DIS 11451-1:2003 shall be used to establish the test field conditions.
4.1.2.

Calibration
For transmission-line-systems (TLS) one field probe at the facility reference point shall be used.
For antennae, four field probes at the facility reference line shall be used.
4.1.3.

Test phase
The vehicle shall be positioned with the centre line of the vehicle on the facility reference point or line. 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 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.

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.
4.4.

Readings
The maximum of the readings relative to the limit (horizontal/vertical polarisation) in each of the 13 frequency bands shall be taken as the characteristic reading at the frequency at which the measurements were made.

Stripline testing
4.4.1.

Test method
This test method consists of subjecting the wiring harness connecting the components in an ESA to specified field strengths.
4.4.2.

Test methodology
The test shall be performed according to ISO 11452-5 (2nd edition 2002).
4.5.

800 mm stripline testing
4.5.1.

Test method
The 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 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.
4.5.2.

Test methodology
4.5.2.1.

Positioning of stripline
The 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.
4.5.2.2.

Calibration of the stripline
A 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.
4.5.2.3.

Installation of the ESA under test
The 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.
4.5.2.4.

Main wiring loom and sensor/actuator cables
The 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.
