FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION

There is a specific need for documents to define acceptable low frequency performance of all

electrical/electronic products. CISPR 36 has been developed to serve the electric and hybrid

electric road vehicle and related industries with test methods and limits that provide satisfactory

protection for radio reception.

Compliance with this document is sometimes insufficient for the protection of receivers used in

the residential environment nearer than 10 m to the vehicle. It also sometimes does not provide

sufficient protection for new types of radio transmissions.

LIMITS AND METHODS OF MEASUREMENT FOR
THE PROTECTION OF OFF-BOARD RECEIVERS BELOW 30 MHz
1 Scope

This document defines limits for 3 m measurement distance and methods of measurement that

are designed to provide protection for off-board receivers (at 10 m distance) in the frequency

range of 150 kHz to 30 MHz when used in the residential environment.

NOTE Protection of receivers used on board the same vehicle as the disturbance source(s) is covered by CISPR 25.

This document applies to the emission of electromagnetic energy which might cause

interference to radio reception and which is emitted from electric and hybrid electric vehicles

propelled by an internal traction battery (see 3.2 and 3.3) when operated on the road.

This document applies to vehicles that have a traction battery voltage between 100 V and

1 000 V.

Electric vehicles to which CISPR 14-1 applies are not in the scope of this document.

This document applies only to road vehicles where an electric propulsion is used for sustained

speed of more than 6 km/h.

Vehicles where the electric motor is only used to start up the internal combustion engine

(e.g. "micro hybrid") and vehicles where the electric motor is used for additional propulsion only

during acceleration (e.g. "48 V mild hybrid vehicles") are not in the scope of this document.

The radiated emission requirements in this document are not applicable to the intentional

transmissions from a radio transmitter as defined by the ITU including their spurious emissions.

Annex C lists work being considered for future revisions.

5 Methods of measurement
5.1 Measurement instruments
5.1.1 Measuring receiver
5.1.1.1 General

The measuring receiver (including FFT-based measurement instruments) shall comply with the

requirements of CISPR 16-1-1:2015. Either manual or automatic frequency scanning may be

used.

A preamplifier can be used between the antenna and measuring receiver in order to achieve

the 6 dB noise floor requirements (see 5.2.1.2). If a preamplifier is used to achieve the 6 dB

noise floor requirement, the laboratory should establish a procedure to avoid overload of the

preamplifier, such as using a step attenuator. The laboratory should also ensure the receiver is

not overloaded in all measurement scenarios, with or without an external preamplifier.

5.1.1.2 Spectrum analyser parameters

The scan rate of the spectrum analyser shall be adjusted for the CISPR frequency band and

detection mode used. The maximum scan rate shall comply with the requirements of
CISPR 16-2-3.

Spectrum analysers may be used for performing compliance measurements to this document

providing the precautions cited in CISPR 16-1-1:2015 on the use of spectrum analysers are

adhered to and that the broadband emissions from the product being tested have a repetition

frequency greater than 20 Hz.
The minimum scan time and resolution bandwidth (RBW) are listed in Table 2.

When a spectrum analyser is used for measurements, the video bandwidth shall be at least

The measurement time of the scanning receiver shall be adjusted for the CISPR frequency band

and detection mode used. The minimum measurement time, maximum step size and bandwidth

(BW) are listed in Table 3.

5.1.2 Magnetic field antenna

For measuring the magnetic field, an electrically-screened loop antenna shall be used (see

CISPR 16-1-4:2019, 4.4.2).
5.1.3 Measurement instrumentation uncertainty

The measurement instrumentation uncertainty shall be calculated as described in Annex A.

Measurement instrumentation uncertainty shall not be taken into account in the determination

of compliance.
Examples of uncertainty budgets are given in Annex B. If the calculated expanded

measurement instrumentation uncertainty exceeds that of the corresponding example in

Annex B, the value of the expanded uncertainty shall be documented in the test report.

NOTE The provisions for measurement instrumentation uncertainty (MIU) in this document do not follow
