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.

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 and3.3) when operated on the road.

Vehicles covered by CISPR 36 have a traction battery voltage between 100 V and 1 000 V.

Electric vehicles that are subjected to CISPR 14-1 are exempt from the application 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.

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

The radiated emission requirements in this document are not intended to be 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.

This part of IEC 61000 pertains to emission and immunity test methods for electrical and electronic equipment using various types of transverse electromagnetic (TEM) waveguides. These types include open structures (for example striplines and electromagnetic pulse simulators) and closed structures (for example TEM cells). These structures can be further classified as one-port, two-port, or multi-port TEM waveguides. The frequency range depends on the specific testing requirements and the specific TEM waveguide type.

The object of this standard is to describe

TEM waveguide characteristics, including typical frequency ranges and equipment-under-test (EUT) size limitations;

TEM waveguide validation methods for electromagnetic compatibility (EMC) tests;

the EUT (i.e. EUT cabinet and cabling) definition;

test set-ups, procedures, and requirements for radiated emission measurements in TEM waveguides; and

test set-ups, procedures, and requirements for radiated immunity testing in TEM waveguides.

NOTE Test methods are defined in this standard for measuring the effects of electromagnetic radiation on equipment and the electromagnetic emissions from equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for quantitative determination of effects for all end-use installations. The test methods defined are structured for a primary objective of establishing adequate reproducibility of results at various test facilities for qualitative analysis of effects.

This standard does not intend to specify the tests to be applied to any particular apparatus or system(s). The main intention of this standard is to provide a general basic reference for all interested product committees of the IEC. For radiated emission measurements, product committees should select emission limits and measurement methods in consultation with CISPR standards. For radiated immunity testing, product committees remain responsible for the appropriate choice of immunity tests and immunity test limits to be applied to equipment within their scope. This standard describes test methods that are separate from those of IEC 61000-4-3 [34].[1]

 

[1]   These other distinct test methods may be used when so specified by product committees, in consultation with CISPR and TC 77.

This generic EMC emission standard is applicable only if no relevant dedicated product or product family EMC emission standard has been published.

This part of IEC 61000 for emission requirements applies to electrical and electronic equipment intended for use at residential (see 3.1.14) locations. This part of IEC 61000 also applies to electrical and electronic equipment intended for use at other locations that do not fall within the scope of IEC 61000-6-8 or IEC 61000-6-4.

The intention is that all equipment used in the residential, commercial and light-industrial environments shall be covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt the requirements in IEC 61000-6-3 shall be applied.

The conducted and radiated emission requirements in the frequency range up to 400 GHz are considered essential and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the locations included within this standard. No measurement needs to be performed at frequencies where no requirement is specified.

The emission requirements in this standard are not intended to be applicable to the intentional transmissions and their harmonics from a radio transmitter as defined by the ITU.

NOTE 1 Safety considerations are not covered by this standard.

NOTE 2 In special cases, situations will arise where the levels specified in this standard will not offer adequate protection; for example where a sensitive receiver is used in close proximity to an equipment. In these instances, special mitigation measures may have to be employed.

NOTE 3 Disturbances generated in fault conditions of equipment are not covered by this standard.

NOTE 4 As the requirements in this standard are more stringent or equivalent to those requirements in IEC 61000-6-4 and IEC 61000-6-8, equipment fulfilling the requirements of this standard comply with the requirements of IEC 61000-6-4 and IEC 61000-6-8.

This generic EMC emission standard is applicable only if no relevant dedicated product or product family EMC emission standard has been published.

This part of IEC 61000 for emission requirements applies to electrical and electronic equipment intended for use in commercial and light-industrial (see 3.1.3) locations. This part applies to equipment that satisfy the following restrictions of use:

is defined as professional equipment (see 3.1.13),

requires professional installation and maintenance (see 3.1.14 and Clause 6),

is not intended to be used in residential locations (see 3.1.16).

IEC 61000-6-3 applies to electrical and electronic equipment intended for use at commercial and light-industrial locations that do not satisfy these restrictions.

The intention is that all equipment used in the residential, commercial and light-industrial environments shall be covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt the requirements in IEC 61000-6-3 shall be applied.

Emission requirements within the frequency range 0 Hz to 400 GHz are covered.

The conducted and radiated emission requirements in the frequency range up to 400 GHz are considered essential and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the locations included within this standard.

NOTE 3 Disturbances generated in fault conditions of equipment are not covered by this standard.

NOTE 4 Equipment which complies with IEC 61000-6-3 are suitable for use within these defined locations.

In the first paragraph, replace “a.c.” with “AC”.

In Note 2, replace "and future IEC/TR 61000-3-14" with "and IEC/TR 61000-3-14".
