IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://webapp.etsi.org/IPR/home.asp).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
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 [15] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulation.
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 [4] as amended), and
Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and
telecommunications terminal equipment and the mutual recognition of their conformity ("the R&TTE Directive" [5]).
Technical specifications relevant to the EMC Directive and the R&TTE Directive are given in annex A.
The present document is based upon the standard for marine navigational equipment EN 60945 [3], and other standards
where appropriate, to meet the essential requirements of Council Directives 89/336/EEC [4] and 1999/5/EC [5]
The present document, and its product related parts are based on the current EMC product standards for marine radio
equipment published by ETSI. It should be noted that two of these EMC standards have also been published in the
Official Journal of the European Commission referring to the EMC Directive.
The present document is part 1 of a multi-part deliverable covering the ElectroMagnetic Compatibility (EMC) standard
for marine radio equipment and services, as identified below:
Part 1: "Common technical requirements";
Part 2: "Specific conditions for VHF radiotelephone transmitters and receivers";
Part 4: "Specific conditions for Narrow-Band Direct-Printing (NBDP) NAVTEX receivers";
Part 5: "Specific conditions for MF/HF radiotelephone transmitters and receivers".

The present document is part of a set of standards designed to fit in a modular structure to cover all radio and
telecommunications terminal equipment under the R&TTE Directive [5]. Each standard is a module in the structure.

The left hand edge of the figure 1 shows the different clauses of article 3 of the R&TTE Directive [5].
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 [4].
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [16] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
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 [5] 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 [5] 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
Figure 2 gives an enlargement of the EMC layer which is judged to be appropriate in view of this harmonized standard

1 Scope
The present document contains the common requirements for marine radio communications equipment and associated
ancillary equipment, in respect of ElectroMagnetic Compatibility (EMC).
The provisions of the present document apply to marine radio equipment not covered in the scope of the Council
Directive on marine equipment (the "Marine Equipment Directive" 96/98/EC [6]).
Product dependent arrangements necessary to perform the EMC tests on dedicated types of marine radio
communications equipment, and the assessment of test results, are detailed in the appropriate product related parts of
the present document.
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 marine radio equipment and associated ancillary equipment.
In case of differences (for instance concerning special conditions, definitions, abbreviation) between the present
document and the relevant product related part of the present document, the product related part takes precedence.
For the further content of the present document, the expression "radio equipment" is taken to mean marine radio
communications equipment, in each individual case.
Technical specifications related to the antenna port of radio equipment and 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
The environment classification used in the present document refers to the environment classification used in:
- EN 60945 [3] for marine navigational equipment,
that means to the maritime environment.
Marine radio communications equipment meeting the EMC requirements set out in EN 60945 [3] is deemed to meet
also the EMC requirements for the residential, commercial and light industrial environment as defined in
EN 61000-6-3 [1] and EN 61000-6-1 [2].
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus intended to be
used in the maritime environment. The levels, however, do not cover extreme cases which may occur in any location
but with low probability of occurrence.
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
