GB/T 33014 consists of the following parts under the general title Road vehicles — Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy:
——Part 1: General;
——Part 2: Absorber-lined shielded enclosure;
——Part 3: Transverse electromagnetic (TEM) cell;
——Part 4: Bulk current injection (BCI);
——Part 5: Stripline;
——Part 7: Direct ratio frequency (RF) power injection;
——Part 8: Immunity to magnetic field;
——Part 9: Portable transmitters;
——Part 10: Immunity to conducted disturbances in the extended audio frequency range;
——Part 11: Reverberation chamber.
This part is Part 5 of GB/T 33014.
This part is developed in accordance with the rules given in GB/T 1.1-2009.
This part has been redrafted and modified in relation to ISO 11452-5: 2002 Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 5: Stripline.
The technical deviations between this part and ISO 11452-5: 2002 and their justifications are as follows:
——Clause 1 is normatively prepared in accordance with GB/T 1.1-2009, and those given in Clause 1 are no longer suited to move to Clause 4;
——ISO 11452-1 referenced in the original international standard is changed to GB/T 33014.1 modified in relation to ISO 11452-1;
——by reference to relevant contents given in other standards, a supplementary explanation (εr≤1.4) is added for the insulating base and the insulating support mentioned in Sub-clause 5.3.1 to facilitate the operation of the standard;
——“AN, see Annex C for a schematic” given in Sub-clause 5.3.1 of the original international standard is changed to “AN, see Annex A of GB/T 33014.2-2016 for a schematic”, which is equivalent to the former in contents, to avoid duplication of provisions on the same content and incomplete unification of the original international standard;
——GB/T 33014.2-2016 is added in "Normative references";
——in order to realize the consistency with Part 1 in the understanding and representation method, I, II, III, IV, V given in Table C.1 are changed to L1, L2, etc., and I, II, III, etc. are understood as statues I, II, III, etc.;
The following editorial change has been made in this part:
——"Foreword" and "Introduction" in the original international standard are deleted;
——Annex C in the original international standard is deleted.
This part was proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
This part is under the jurisdiction of the National Technical Committee of Auto Standardization (SAC/TC 114).
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.

GB/T 33014.2-2016 Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 2: Absorber-lined shielded enclosure (ISO 11452-2: 2004, MOD)
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).
Dimensions in millimetres
Key:
1——DUT; 5——insulating base;
2——wiring harness; 6——artificial network(s);
3——peripheral device; 7——active conductor;
4——terminating resistance; 8——ground plane.

5.2 Test apparatus
The test apparatuses are shown in Figure 2.
5.3 Test set-up
5.3.1 Test set-up
The test set-up should be as shown in Figures 1 and 2.
Install the DUT next to the active conductor, with an edge parallel to it.
The distance between the DUT and the closest edges of the active conductor shall be
200 mm. The distance from any peripheral device to the closest edge of the active conductor shall be at least 200 mm.
