Foreword
This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [4] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Council Directive on the approximation of the laws of
the Member States relating to electromagnetic compatibility ("the EMC Directive") (89/336/EEC [2] as amended) and

The left hand edge of the figure 1 shows the different clauses of article 3 of the R&TTE Directive [1].
For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present
document essential requirements in these areas have to be adopted by the Commission. If such essential requirements
are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to
be specified by function or interface type.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The
scopes of these standards are specified either by frequency (normally in the case where frequency bands are
harmonized) or by radio equipment type.
For article 3.1b the diagram shows EN 301 489, the multi-part product EMC standard for radio used under the EMC
Directive [2].
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [3] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio
spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant
essential requirement under the R&TTE Directive [1] is adopted by the Commission and if the equipment in question is
covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential
requirements under the R&TTE Directive [1] may be covered in a set of standards.
The modularity principle has been taken because:
• it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and
functions it is not practicable to produce a single standard for each possible combination of functions that may
occur in an equipment;
• it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions without requiring alteration of
standards that are already published;
- it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of
conformity assessment.
Figure 2 gives an enlargement of the EMC layer which is judged to be appropriate in view of the present document
derivation.

Figure 2: The new radio EMC harmonized standard
The present document is part 1 of a multi-part EMC standard for radio equipment which is structured in the following
way:
- One EMC standard for all radio equipment made up of several parts.
- All common technical requirements for EMC emission and immunity have been placed in EN 301 489-1,
which is the present document.
- Separate parts have been developed to cover specific product related radio equipment test conditions, test
arrangements, performance assessment, performance criteria, etc.
- A clause is included in each of the specific radio parts, entitled "special conditions", which is used as
appropriate to cover any deviations or additions to the common requirements set out in the present document.
To demonstrate an adequate level of EMC protection, the present document is to be used together with the appropriate
specific radio part of the standard.
It is recognized that there may be circumstances where none of the existing specific product related radio parts covers
the required conditions for a particular radio equipment/service e.g. in case of the initial introduction of a new radio
service or a special application. In this situation the present document can be used together with specific information for
the radio equipment provided by the manufacturer, for the purposes of testing to the EMC requirements set out in the
present document.
In all cases where a radio product falls within the scope of a specific product related radio part of the standard, the
product related part takes precedence.

1 Scope
The present document contains the common requirements for radio communications equipment and associated ancillary
equipment, in respect of ElectroMagnetic Compatibility (EMC).
Product dependent arrangements necessary to perform the EMC tests on dedicated types of radio communications
equipment, and the assessment of test results, are detailed in the appropriate product related parts of EN 301 489.
The present document, together with the product related part, specifies the applicable EMC tests, the methods of
measurement, the limits and the performance criteria for radio equipment and associated ancillary equipment. In case of
differences (for instance concerning special conditions, definitions, abbreviation) between this part and the relevant
product related part of EN 301 489, the product related part takes precedence.
Technical specifications related to the antenna port of radio equipment and radiated emissions from the enclosure port
of radio equipment and combinations of radio and associated ancillary equipment are not included in the present
document. Such technical specifications are normally found in the relevant product standards for the effective use of the
radio spectrum.
The environment classification used in the present document refers to the environment classification used in:
- EN 50081-1 [5] and EN 50082-1 [6] for the residential, commercial and light industrial environment; or
- TR 101 651 [16] for the telecommunication centre environment; or
- ISO 7637-1 [14] and ISO 7637-2 [15] for the vehicular environment.
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus intended to be
used in the environments mentioned above. The levels, however, do not cover extreme cases which may occur in any
location but with low probability of occurrence. The applicable environment(s) shall be declared by the manufacturer
and shall be in accordance with the equipment documentation.
The present document may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomenon is permanently present, e.g. a radar or
broadcast site in the near vicinity. In such a case it may be necessary to use special protection applied to either the
source of interference or the interfered part or both.
Compliance of radio equipment to the requirements of the present document does not signify compliance to any
requirements related to spectrum management or to the use of the equipment (licensing requirements).
Compliance to the requirements of the present document does not signify compliance to any safety requirements.
However, it is the responsibility of the assessor of the equipment to record in the test report any observations regarding
the test sample becoming dangerous or unsafe as a result of the application of the tests called for in the present
document.
NOTE: Radio equipment for use in maritime environment is covered by other ETSI EMC standards.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
ancillary equipment: equipment (apparatus), used in connection with a receiver or transmitter
NOTE: It is considered as an ancillary equipment (apparatus) if:
- the equipment is intended for use in conjunction with a receiver or transmitter to provide additional
operational and/or control features to the radio equipment, (e.g. to extend control to another
position or location); and
- the equipment cannot be used on a stand alone basis to provide user functions independently of a
receiver or transmitter; and
- the receiver or transmitter, to which it is connected, is capable of providing some intended
operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a sub-
unit of the main equipment essential to the main equipment basic functions).
base station equipment: radio and/or ancillary equipment intended for operation at a fixed location and powered
directly or indirectly (e.g. via an AC/DC converter or power supply) by the AC mains network, or an extended local DC
mains network
continuous phenomena (continuous disturbance): electromagnetic disturbance, the effects of which on a particular
device or equipment cannot be resolved into a succession of distinct effects
NOTE: See IEC 60050-161 [19].
enclosure port: physical boundary of the apparatus through which electromagnetic fields may radiate or impinge
NOTE: In the case of integral antenna equipment, this port is inseparable from the antenna port.
host equipment: any equipment which has a complete user functionality when not connected to a radio
communications equipment, and to which this radio equipment provides additional functionality, and to which
connection is necessary for this radio equipment to offer additional functionality, and in which the transceiver part of
the radio equipment is physically installed
NOTE: This also covers any device that would accept a variety of radio modules, where the original user
functionality of the host equipment is not affected.
integral antenna: antenna which may not be removed during the tests, according to the manufacturer's statement
manufacturer: manufacturer of the equipment, or his authorized representative, or an equipment supplier to the
European market
mobile equipment: receiver, transmitter or transmitter/receiver (transceiver) intended for installation and use in a
vehicle, and powered by the main battery of the vehicle

4 Test conditions
4.1 General
The equipment shall be tested under normal test conditions according to the relevant product and basic standards or to
the information accompanying the equipment, which are within the manufacturers declared range of humidity,
temperature and supply voltage. The test conditions shall be recorded in the test report.
The test configuration and mode of operation shall represent the intended use and shall be recorded in the test report.
For emission and immunity tests, specific product related information on the test modulation, test conditions and tests
arrangements, etc., are found in the part of EN 301 489 dealing with the particular type of radio equipment.
4.2 Arrangements for test signals
Adequate measures shall be taken to avoid the effect of immunity test signals on both the measuring equipment and the
signal sources for the wanted signals located outside the test environment.
4.2.1 Arrangements for test signals at the input of transmitters
The signal source providing the transmitter under test with the modulation signal for the normal test modulation shall be
located outside the test environment, unless the transmitter is modulated by its own internal source, see the relevant part
of EN 301 489.
The transmitter shall be modulated with normal test modulation, by an internal or external signal source capable of
delivering the normal test modulation as specified in the relevant part of EN 301 489.
4.2.2 Arrangements for test signals at the output of transmitters
The measuring equipment for the wanted RF output signal from the transmitter under test shall be located outside the
test environment.
For transmitters with an integral antenna, the wanted RF output signal to establish a communication link shall be
delivered from the EUT to an antenna located within the test environment. This antenna shall be connected to the
external measuring equipment by a coaxial cable.
For transmitters with a removable antenna, the wanted RF output signal to establish a communication link shall be
delivered from the antenna connector to the external measuring equipment by a shielded transmission line, such as a
coaxial cable. Adequate measures shall be taken to minimize the effect of unwanted common mode currents on the
external conductor of the transmission line at the point of entry to the transmitter.
Unless otherwise specified in the relevant part of EN 301 489 for the particular type of radio equipment, the level of the
wanted RF output signal in transmit mode of operation shall be set to the maximum rated RF power for the EUT,
modulated with the normal test modulation.
