GB/T 33014.1-2016Road vehicles -- Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy -- Part 1: General (English PDF)

Foreword

GB/T 33014 "Road vehicles - Component test methods for electrical/electronic

disturbances from narrowband radiated electromagnetic energy" consists of the

following parts.

- Part 1.General;

- Part 2.Absorber-lined shielded enclosure;

- Part 3.Transverse electromagnetic (TEM) cell;

- Part 4.Bulk current injection (BCI);

- Part 5.Stripeline;

- Part 7.Direct radio frequency (RF) power injection;

- Part 8.Magnetic field immunity;

- Part 9.Portable transmitter simulation;

- Part 10.Conduction immunity method for extended audio range;

- Part 11.Reverberation chamber.

This Part is Part 1 of GB/T33014.

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 11452-1.2005 "Road

vehicles - Component test methods for electrical disturbances from narrowband

radiated electromagnetic energy - Part 1.General principles and terminology" and ISO

11452-1 AMD 1.2008.

The technical differences between this Part and ISO 11452-1.2005 are as follows.

- PREPARE Clause 1 according to the provisions of GB/T 1.1-2009;

- ADD "Normative references" according to the provisions of GB/T1.1-2009, which

includes a number of standards used in the text;

- Because the original international standard of this series standard has been

increased to 11 parts, but the other part cannot be synchronously converted to

Part 1 ~ Part 5, so it is hard to describe in Table 1.Thus, in this Part, it deletes

Part 7 in Table 1 of the original international standard, and retains only Part 1 ~

Part 5 that are synchronously converted;

- The definition of the terms in the original international standard are deleted and

the national standard is referenced, to avoid duplication of definitions;

- The contents of Clause 3 of the original international standard are included in 4.1,

the contents of the original 4.1 are included in 4.2, and Clause 3 and Clause 4 of

the original international standard are merged together to maintain structural

correspondence with the original international standard;

- An amendment of the original international standard is added in 2008, which has

made a great adjustment to Annex A "Function performance status classification

(FPSC)"; considering that internationally the understanding and requirements of

function performance status classification (FPSC) tend to adopt the new version,

so in this Part, the Amendment 2008 is applied to Annex A.

- Because the principle of function performance status classification (FPSC) is

described both in A.1 and A.2 of Annex A of the original international standard

(2008 edition), and the content and heading are not fully matched, in this Part, the

contents of the upper and lower paragraphs are arranged and the principle of

function performance status classification (FPSC) is integrated into A.2, so that

the content and heading of the upper and lower paragraphs are fully matched, to

facilitate the understanding and use of the standard.

The following editorial changes have been made in this Part.

- DELETE the foreword, introduction and bibliography 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 1.General

1 Scope

This Part of GB/T 33014 specifies the basic conditions, test instrumentations and test

procedures of the immunity test for electrical/electronic components (ESA) to

continuous electrical disturbances from narrowband radiated electromagnetic energy.

This Part applies to electrical/electronic components for M, N, O, L 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 dated edition cited applies. For undated

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

applies.

GB/T 29259 Road vehicle - Electromagnetic compatibility terminology

3 Terms and definitions

For the purpose of this document, the terms and definitions defined in GB/T 29259

apply.

4 Test conditions

A single standard test might not reveal all the information about the DUT. It is thus

necessary for users of this series of standards to anticipate the appropriate test

conditions, select applicable parts of GB/T 33014 and define function performance

indicators of DUT.

The characteristics of the DUT determine the type and frequency of modulation to be

used.

5 Test instrumentation

It shall establish uniform measurement conditions at radio frequencies, which requires

specific grounding practices as follows.

In the frequency range limited by the bandwidth of both the amplifier and the antenna

(transducer) in use, the amplifier harmonic content (up to the fifth harmonic) shall be

at least 12 dB lower than the carrier wave (at least 6 dB lower at frequencies above 1

GHz), unless otherwise specified for a particular test method or in the test plan.

6 Test procedure

The following methods are used in certain parts of GB/T 33014.

The forward power required for the test signal can be derived from the following

formula according to the calibrated value.

Annex A

(normative)

Function performance status classification (FPSC)

This annex describes the functional performance statue of a device, that is, how a

particular device works as expected under the influence of a particular test signal,

giving a general definition method for the qualification situation of the vehicle in and

after the narrowband radiated electromagnetic disturbance test. The definition method

shall be used in conjunction with the relevant part of GB/T 33014.
