This Part is Part 5 of GB/T 33014.

This Part is drafted in accordance with the rules given in GB/T 1.1-2009.

This Part uses the re-drafting method to modify and adopt ISO 11452-5.2002 "Road

vehicles - Component test methods for electrical disturbances from narrowband

radiated electromagnetic energy - Part 5.Stripeline".

The technical differences between this Part and ISO 11452-5.2002 are as follows.

- PREPARE Clause 1 according to the provisions of GB/T 1.1-2009, and MOVE the

contents that are not suitable for Clause 1 to Clause 4;

- REPLACE the reference standard ISO 11452-1 WITH GB/T 33014.1 modifying

and adopting ISO 11452-1;

- ADD a supplementary instruction (epsilonr <= 1.4) to insulating base and insulating

support in 5.3.1 with reference to the relevant contents in other standards, to

facilitate the standard operation;

- The artificial network in 5.3.1 of the original international standard references

Annex C, which is modified to the equivalent Annex A of GB/T 33014.2-2016, to

avoid duplication of the same content and the inconsistency of the original

international standard

- ADD GB/T 33014.2-2016 in the normative references;

- For consistency in understanding and presentation with Part 1, I, II, III, IV, V of

Table B.1 are changed to L1, L2, etc., and I, II, III, etc. are understood as status I,

II, III, etc.

The following editorial changes have been made in this Part.

- DELETE the foreword and introduction of the original international standard;

- DELETE Annex C of the original international standard.

This Part is proposed by Ministry of Industry and Information Technology of the

People's Republic of China.

This Part is under the jurisdiction of 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 of GB/T 33014 specifies the immunity test for electrical/electronic

components to continuous electrical disturbances from narrowband radiated

electromagnetic energy - stripline.

2 Normative reference

The following referenced documents are indispensable for the application of this

document. For dated references, only the dated edition cited applies. For undated

references, the latest edition of the referenced document (including all amendments)

applies.

GB/T 33014.1 Road vehicles - Component test methods for electrical/electronic

disturbances from narrowband radiated electromagnetic energy - Part 1.General

(GB/T 33014.1-2016, ISO 11452-1.2005, MOD)

3 Terms and definitions

For the purposes of this document, the terms and definitions given in GB/T 33014.1

apply.

4 Test conditions

The useful frequency range of stripline is from 0.01 MHz to 400 MHz. The users shall

specify the test severity level or levels over the frequency range. See annex B for

suggested severity levels.

5 Test apparatus and instrumentation

A stripline (see annex A) shall set up a region of uniform electromagnetic fields. The

stripline is to expose at least 1 m of the wiring harness under the test region (see Figure

1).

6 Test

Alternatively, the relation between field strength and net power may be determined by

placing a calibrated field probe as close as possible to the centre of the stripline, with

respect to the longitudinal and transverse axes under the active conductor.

Annex A

(informative)

Stripline design

A 50 ohm stripline construction is shown in Figures A.1 to A.4.Dimension I shall be at

least 2 m. The ratio of b to h determines the characteristic impedance. If dimension b

is greater than h, the characteristic impedance is calculated as Equation (A.1).

Annex B

(informative)

Function performance status classification (FPSC)

Suggested test severity levels and the frequency bands of this Part are given in Table

A.1 and Table A.2, respectively.
