Foreword
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents".
Drafting.
This document replaces GB 34660-2017 "Electromagnetic Compatibility Requirements and Test Methods for Road Vehicles". Compared with GB 34660-2017,
Apart from structural adjustments and editorial changes, the main technical changes are as follows.
a) The definition of the term "immunity-related function" has been changed (see 3.3,.2017 version 3.3);
(b) The limits for narrowband electromagnetic radiation emissions from vehicles under the 10m and 3m methods have been revised (see 4.3,.2017 version 4.3);
c) The method of replacing vehicle narrowband electromagnetic radiation emission measurement with vehicle radio frequency measurement has been removed (see 4.3.3 in the.2017 version);
d) The vehicle radiated immunity requirements have been modified, adding immunity requirements for the.2000MHz~6000MHz range and the overall vehicle reverberation chamber.
Alternative testing methods (see 4.4,.2017 edition);
e) The radiated immunity requirements for electrical/electronic components have been changed, adding immunity requirements for the.2000MHz~6000MHz range and for components.
Alternative test methods for reverberation chambers have been proposed, with the 800mm strip method removed (see 4.7,.2017 version 4.7).
f) The ESA has changed the test conditions and functional characteristic requirements for transient conducted immunity along the power line, removing pulse 4 and adding...
The test pulse parameters have been added (see 4.8,.2017 version 4.8);
g) Alternative test methods for whole vehicle BCI have been removed (see 5.4.1.4 in the.2017 version);
h) Added relevant management regulations for vehicle type inspection (see 6.1);
i) The technical conditions and test items for determining whether a vehicle is of the same type have been added (see 6.2);
j) The vehicle broadband electromagnetic radiation emission test has been modified (see Appendix B, 5.2,.2017 edition);
k) The vehicle narrowband electromagnetic radiation emission test has been modified (see Appendix C, 5.3,.2017 edition);
l) The vehicle electromagnetic radiation immunity test has been modified (see Appendix D, 5.4 of the.2017 edition);
m) The ESA broadband electromagnetic radiation emission test has been modified (see Appendix E, 5.5,.2017 edition);
n) The ESA narrowband electromagnetic radiation emission test has been modified (see Appendix F, 5.6 of the.2017 edition);
o) The ESA's immunity test for electromagnetic radiation has been modified (see Appendix G, 5.7 of the.2017 edition);
p) The ESA immunity test for transient conduction along power lines has been modified (see Appendix H, 5.8,.2017 edition);
q) The ESA transient conducted emission test has been modified (see Appendix I, 5.9 of the.2017 edition).
