ANNEX 6
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.
This method concerns both configurations of vehicle: (a) Other than ‘REESS charging mode coupled to the power grid’; (b) ‘REESS charging mode coupled to the power grid’.
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 11451-2.
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, BCI (bulk current injection) method according to ISO 11451-4 shall be used in the frequency range 20 to 2,000 MHz with levels defined in paragraph 6.8.2.1. of this Regulation.
2.
Vehicle state during tests
2.1.
Vehicle in configuration other than ‘REESS charging mode coupled to the power grid’.
2.1.1.
The vehicle shall be in an unladen condition except for necessary test equipment.
2.1.1.1.
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.
For vehicles of categories L1 and L2 the steady speed shall normally be turned at 25 km/h.
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, belts or chains may be disconnected (e.g. trucks, two- and three-wheel vehicles).
2.1.1.2.
Basic vehicle conditions The paragraph defines minimum test conditions (as far as applicable) and failure criteria for vehicle immunity tests.
Other vehicle systems, which can affect immunity related functions, shall be tested in a way to be agreed between manufacturer and Technical Service.
‘50 km/h mode’ vehicle test conditions
Failure criteria
Vehicle speed 50 km/h (respectively 25 km/h for L1, L2 vehicles) ±20 per cent (vehicle driving the rollers).
If the vehicle is equipped with a cruise control system, it shall be used to maintain the required constant vehicle speed and maintained without any deactivation.
Speed variation greater than ±10 per cent of the nominal speed.
In case of automatic gearbox: change of gear ratio inducing a speed variation greater than ±10 per cent of the nominal speed.
