FOREWORD
This Standard modifies and adopts the American Society of Automotive Engineers standard SAE J551-5
JAN2004 “Performance levels and methods of measurement of electric and magnetic field strength from
electric vehicles”. Compared with SAE J551-5 JAN2004, the main technical differences and reasons are
as follows.
- In Chapter 2 “Normative References”, this Standard cites GB/T 4365 to replace the terms and
definitions of SAE J551-1; and cites GB/T 14023 to replace SAE J551-2; both of them contain
the same technical contents and are interchangeable. Delete the following publications that are
merely taken as references - “Federal Regulation No. 47 of the United States –
Communications; Part 15 – Radio frequency equipment” and “IEEE std. 291”.
- In Section 4.2 “Conducted emissions limits”, delete the requirements of 250 μV limit for
non-commercial areas. That is, the limits are unified, regardless of commercial or
non-commercial areas.
- This Standard adds a new Annex A “Rod antenna calibration – The equivalent capacitance
substitution method”. Derived from the version 2001 of this Standard, it is intended for guiding
the accuracy of measurement. And it is same as the Annex A in SAE J551-5 DEC1997.
Compared with SAE J551-5 JAN 2004, the difference of chaptering is as follows.
- This Standard combines the Chapters 6, 7 and 8 of SAE J551-5 JAN2004 which are related to
measurement method INTO Chapter 5 of this Standard. The corresponding sections are 5.4, 5.5,
and 5.6 respectively.
- A new Annex A is added in this Standard.
- Annex B of this Standard corresponds to Annex A of SAE J551-5 JAN2004.
This Standard specifies the limits and measurement methods of electric and magnetic field strength from
electric vehicles. The frequency range is 9 kHz ~ 30 MHz. It coordinates with the frequency range of
30MHz ~ 1,000 MHz specified in GB 14023 “Limits and methods of measurement of radio interference
characteristics of vehicles, motorboats and spark ignition engine-driven devices”.
This Standard replaces the previous version GB/T 18387-2001 “Performance levels and methods of
measurement of electric and magnetic field strength from electric vehicles, broadband, 9 kHz to 30 MHz”.
Compared with the previous version, the main changes of this version are as follows.
- In Chapter 1, further clarify the applicable scope of this Standard;
- In Chapter 2, add the references. GB 9254, ANSI C63.4, and ANSI C63.12;
- In Chapter 4, there is significant change of the disturbance limits for radiated emissions
(comparison between Figures 1 & 2 of this version AND Figures 1 & 2 of the prevision version).
Add Section 4.2 the limits of conducted emissions for battery-charging systems mounted on the
vehicle (see Table 3);
- In Section 5.2 of Chapter 5, the distance for measurement of magnetic field specified is changed
from 1 m ± 0.2 m (the previous version) TO 3 m ± 0.2 m (this version). Add new Section 5.3
“Requirements for measurement site of conducted emissions”. Sections 5.4 & 5.5 of this version
correspond to Chapters 6 and 7 of the previous version respectively. Add new Section 5.6
“Measurement of battery-charging systems mounted on the vehicle”;
- In Annex A, Figure A.2 is added;
- Add new Annex B “Notes on conversion of limits for measurement distance from 10 m to 3 m”.
Annex A is normative. Annex B is informative.

Limits and Test Method of Electric and magnetic field Strength
from Electric Vehicles, Broadband, 9 kHz to 30 MHz
1 Scope
This Standard specifies the limits and test method of radiated emissions of electric and magnetic field
from electric vehicles over the frequency range of 9 kHz ~ 30 MHz, and the limits and test method of
conducted emissions over the frequency range of 450 kHz ~ 30 MHz.
Conducted emission measurements in this Standard are applicable only to battery-charging systems
which utilize a switching frequency above 9 kHz, which are mounted on the vehicle, and of which the
power is transferred by metallic conductors. Conducted emissions requirements apply only during
charging of the batteries from AC power lines.
Conducted and radiated emissions measurements of battery-charging systems that use an induction
power coupling device are not covered by this Standard.
Note. GB 14023 shall govern, in the case of measurement of electromagnetic disturbances over the frequency range of 30
MHz ~ 1,000 MHz.

and electronic equipment in the range of 9 kHz ~ 40 GHz

B.1.3 Conversion of limits when f > 15.92 MHz
Whereas both distances of measurement (i.e., 3 m and 10 m) fall within the far-field area, the conversion
of limits presents a certain proportional relation with the distance.
B.2 Limits for magnetic field
Likewise, the original recommended limits for magnetic field strength of peak impulse come from the
technical paper of Georgia Institute of Technology, expressed in dB(μA/m/kHz), and assuming the
measurement at a distance of 10 m.
Where.
f – Expressed in kHz;
Z0= 377 Ω.
Whereas the boundary distance of near/far field is identical for electric and magnetic fields, assuming the
measurement at a distance of 3 m, the limits for electric and magnetic fields may be correlated via the
wave impedance of free space.
