4.10 Supplementary provisions
4.10.1 Whole-vehicles
4.10.1.1 If the vehicle is not fitted with an ESA with immunity-related functions,
the radiation immunity test is not required and may be regarded as meeting the
requirements of 4.4.
4.10.1.2 If the vehicle does not contain an electronic oscillation generator
operating at a frequency greater than 9 kHz, the narrowband electromagnetic
emission test is not required and may be regarded as meeting the requirements
of 4.3.
4.10.2 Electrical/electronic components (ESA)
4.10.2.1 It requires considering the ESA for electromagnetic compatibility. Refer
to Appendix A for the determination method.
4.10.2.2 If the ESA does not contain an electronic oscillation generator with an
operating frequency greater than 9 kHz, the narrowband electromagnetic
emission test is not required, and it may be regarded as meeting the
requirements of 4.6.
4.10.2.3 ESA without state switching, without switching type load and without
inductive loads, it does not require a transient conducted emission test and may
be regarded as meeting the requirements of 4.9.
4.10.2.4 The ESA radiated and conducted immunity performance specified in
4.7 and 4.8 is only relevant to the ESA related to immunity-related functions.
Other ESA may be implemented by reference or negotiated by both parties.
4.10.3 Other instructions
4.10.3.1 During the immunity test process, when the applied interference signal
is within the necessary bandwidth of the on-board receiver, that is, in the
frequency band of the specific radio device as specified in the national standard,
the function determination of the receiver does not have to follow the failure
criterion.
4.10.3.2 Radio frequency transmitters shall be tested in transmission mode. It
does not consider the intentional transmission in the necessary bandwidth
(such as the emission of radio frequency transmission system) and out-of-band
emission. Spurious emissions need to be tested.
Note 1. “Required bandwidth” refers to the bandwidth required for the specified
number of test frequency points. See Appendix B for details.
5.3.5 Data processing and analysis
The maximum readings of the antenna located at the left and right sides of the
vehicle with horizontal polarization and vertical polarization at 14 sub-bands
(see Appendix B.1) shall be recorded as characteristic values of the measured
frequency.
If the test results exceed the limit, analysis shall be performed to ensure that
the measured radiation emission is from the vehicle rather than the background
noise.
5.4 Vehicle immunity to electromagnetic radiation
5.4.1 General
5.4.1.1 This method is used to test the electrical/electronic system immunity
performance of the vehicle. The vehicle shall be fully exposed to the
electromagnetic field and the vehicle shall be monitored during the test.
5.4.1.2 If there is no other requirement, it shall be conducted in accordance with
the test method specified in GB/T 33012.2-2016.
5.4.1.3 Alternative methods may be selected. Vehicles are tested at an outdoor
test field.
5.4.1.4 If the vehicle length is greater than 12 m and/or the width is greater than
2.6 m and/or the height is greater than 4 m, the bulk current injection (BCI)
method may be used in accordance with GB/T 33012.4-2016 in the frequency
range of 20 MHz ~ 2000 MHz.
5.4.2 Vehicle status
5.4.2.1 Except for the necessary test devices, the vehicle shall be unloaded.
5.4.2.2 The engine shall operate normally with a speed of 50 km/h. The stable
speed of category L1 and L2 vehicles shall be 25 km/h (if the vehicle cannot
reach 25 km/h, it shall run at the maximum speed). The vehicle shall be placed
on the dynamometer. If there is no dynamometer, it can be placed on the
insulation support and the minimum ground clearance is guaranteed. The drive
shafts, belts or chains (e.g. trucks, two-wheel vehicles or three-wheel wheels)
can be disconnected.
5.4.2.3 The basic test conditions for the disturbance immunity test of vehicles
are shown in Table 9. The test conditions (status) and failure criteria for other
systems of the vehicle that may affect the immunity-related functions shall be
determined by the manufacturer and the testing institute through negotiation.
c) Bulk current injection (BCI) method. in accordance with the provisions of
GB/T 33014.4-2016;
d) 150 mm strip line method. in accordance with the provisions of GB/T
33014.5-2016;
e) 800 mm strip line method. in accordance with the provisions of 5.7.4.5.
5.7.2 ESA status
5.7.2.1 Test conditions shall comply with the provisions of GB/T 33014.1-2016.
5.7.2.2 The ESA shall be in normal working condition and shall be arranged in
accordance with the provisions of this standard, except for special test methods.
5.7.2.3 At the time of calibration, all auxiliary equipment needed for ESA
operation shall not be placed in the test position, the distance between other
equipment and the reference point shall not be less than 1 m.
5.7.2.4 To ensure the reproducibility of the test results, the signal generation
equipment and line configuration shall be the same as during calibration.
5.7.2.5 If the ESA contains multiple units, the connection lines between the units
shall use the connection harnesses used in the original vehicle. If this cannot
be achieved, the length of the connection line between the electronic control
unit and the artificial power network (AN) shall comply with the requirements of
this standard. The wiring harness shall be terminated in accordance with actual
conditions, i...
