GB/T 21437.1-2021Road vehicles - Test method of electrical disturbances from conduction and coupling - Part 1: Definitions and general considerations (English PDF)

Foreword

This document was drafted in accordance with the rules given in GB/T 1.1-2020

"Directives for standardization - Part 1.Rules for the structure and drafting of

standardizing documents".

This document is Part 1 of GB/T 21437 "Road vehicles - Test method of electrical

disturbances from conduction and coupling". GB/T 21437 has issued the following

parts.

- Part 1.Definitions and general considerations;

- Part 2.Electrical transient conduction along supply lines only;

- Part 3.Electrical transient transmission by capacitive and inductive coupling via

lines other than supply lines.

This document replaces GB/T 21437.1-2008 "Road vehicles - Electrical disturbances

from conduction and coupling -Part 1.Definitions and general considerations".

Compared with GB/T 21437.1-2008, in addition to structural adjustments and editorial

modifications, the main technical changes in this document are as follows.

- Added GB/T 29259 as a reference; Deleted the duplicate terms and definitions with

GB/T 29259 (see Chapter 3);

- Added general test conditions (see Chapter 5);

- Added functional characteristic state classification (FPSC) (see Annex A).

The modification of this document adopts ISO 7637-1.2015 "Road vehicles - Electrical

disturbances from conduction and coupling - Part 1.Definitions and general

considerations".

The technical differences between this document and ISO 7637-1.2015 and the reasons

are as follows.

- To maintain the unity of the expression and understanding of the functional

characteristic status classification (FPSC) among the electromagnetic immunity

series standards, it is changed to refer to Annex A of GB/T 33014.1-2016;

- Change the normative reference "IEC 60050-151" in Chapter 3 of ISO 7637-1.2015

to "GB/T29259", so as to avoid repetition; Deleted the terms and definitions in

ISO 7637-1.2015 that are repeated with GB/T 29259.

Attention is drawn to the possibility that some of the elements of this Standard may be

the subject of patent rights. The issuing authority shall not be held responsible for

identifying any or all such patent rights.

This document was proposed by Ministry of Industry and Information Technology of

the People's Republic of China.

This document shall be under the jurisdiction of National Technical Committee on

Automobiles of Standardization Administration of China (SAC/TC 114).
