Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 5: Stripline
1 Scope
This part specifies stripline tests for determining the immunity of electronic components to electrical disturbances from narrowband electromagnetic energy.
This part is applicable to electrical/electronic components for Categories M, N, O and L vehicles, regardless of the vehicle propulsion 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 (including any amendments) applies.

3 Terms and definitions
For the purpose of this document, the terms and definitions given in GB/T 33014.1 apply.
4 Test conditions
The applicable frequency range for this test method is 0.01 MHz to 400 MHz. The users shall specify the test severity level(s) over the frequency range. See Annex B for recommended test severity levels.
Stripline method is limited to wiring harnesses of equipment, which have a maximum diameter of one-third the stripline height or less. During the test, the wiring harness of the DUT shall be exposed to a disturbance field.
The following standard test conditions shall meet the requirements of GB/T 33014.1:
——test temperature;
——test voltage;
——modulation;
——dwell time;
——frequency step sizes;
——definition of test severity levels;
5 Test apparatus
5.1 Stripline
A stripline (see Annex A), ideally, sets up a region of uniform electromagnetic fields. The primary usage of this form of the stripline is to expose at least 1 m of the wiring harness under the active conductor (see Figure 1).
