Foreword
GB/T 33012 “Road vehicles - Vehicle test methods for electrical disturbances from
narrowband radiated electromagnetic energy” consists of four parts.
- Part 1. General;
- Part 2. Off-vehicle radiation sources;
- Part 3. On-board transmitter simulation;
- Part 4. Bulk current injection (BCI).
This Part is Part 4 of GB/T 33012.
This Part is drafted in accordance with the rules given in GB/T 1.1-2009.
This Part uses the re-drafting method to amend and adopt ISO 11451-4.2006 “Road
vehicles - Vehicle test methods for electrical disturbances from narrowband radiated
electromagnetic energy - Part 4. Bulk current injection (BCI)”.
Technical differences between this Part and ISO 11451-4.2006 and the causes are as
follows.
- Clause 1 is normatively prepared according to the specifications of GB/T 1.1-2009;
- The normative reference ISO 11451-1.2001 is modified to GB/T 33012.1-2016
adopting ISO 11451-1.2005;
- ADD the clause of “Terms and definitions”;
- In order to achieve the same understanding and presentation with Part 1, I, II, III,
IV, V of Table A.1 are modified to L1, L2, etc., and I, II, III, etc. are understood as
status I, II, III, etc.
The following editorial modifications are also made in This Part.
- Clause 3 of the original international standard is modified to Clause 4;
- 4.3 of the original international standard is taken as a separate clause, i.e. Clause
6;
- Clause 4 of the original international standard is modified to Clause 5, and 4.2 is
divided into two sections;
- Clause 5 of the original international standard is modified to Clause 7;
Road vehicles - Vehicle test methods for electrical
disturbances from narrowband radiated electromagnetic
energy - Part 4. Bulk current injection (BCI)
1 Scope
This Part of GB/T 33012 specifies the test conditions, test location, test equipment,
stimulation and monitoring of vehicle, test set-up and test procedure for vehicle test
methods for electrical disturbances from narrowband radiated electromagnetic energy
- bulk current injection (BCI).
This Part applies to M, N and O vehicles (regardless of the vehicle power system, e.g.
spark-ignition engine, diesel engine, electric motor).
2 Normative references
The following referenced documents are indispensable for the application of this
document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
GB/T 33012.1-2016 Road vehicles - Vehicle test methods for electrical disturbances
from narrowband radiated electromagnetic energy - Part 1. General principles and
terminology (ISO 11451-1.2005 + A1. 2008, MOD)
3 Terms and definitions
For the purpose of this document, the terms and definitions given in GB/T 33012.1-
2016 apply.
4 Test conditions
The applicable frequency range for this test method is 1 MHz to 400 MHz. The
frequency range of the BCI test method is a direct function of the current probe
characteristics. More than one type of current probe may be required to cover the
applicable frequency range.
The users shall specify the test severity level(s) over the frequency range. Suggested
lowest forward power to the probe as the threshold of immunity even if this is found
with the injection probe in different positions at different frequencies. A current
measurement probe may optionally be mounted between the current injection probe
and the DUT. It may provide extra useful information but it may also modify the test
conditions. Where this probe is used, the measured current cannot be used to
determine the performance of the DUT, but shall be retained and used during
investigative work for the causes of events and the variances in test conditions after
system modifications.
7.3.3 Closed-loop method
See Annex C for the current measurement probe calibration method.
The RF power to the current injection probe shall be increased until.
- the predetermined maximum test current level, measured using the current
measurement probe, is reached, or
- the maximum forward power defined in the test plan to the injection probe is
achieved.
Record the threshold of susceptibility of the DUT as a function of frequency.
7.4 Test report
When required in the test plan, a test report shall be submitted detailing information
regarding the test equipment, test site, systems tested, frequencies, power levels,
system interactions and any other relevant information regarding the test.
