This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical

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

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

The present document is part 1 of a multi-part deliverable covering the ElectroMagnetic Compatibility (EMC) standard

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.

Figure 1: Modular structure for the various standards used under the R&TTE Directive

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

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

For article 3.1b the diagram shows EN 301 489, the multi-part product EMC standard for radio used under the

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

• 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

- under article 3.3 should the Commission take the necessary decisions without requiring alteration of

• 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

The current EMC product standards for marine radio equipment are all structured as follows:

Clauses 1 to 6 contain information specific to the type of radio equipment covered by the present document:

Clause 8 contains the emission requirements and clause 9 contains the immunity requirements. The requirements set out

- the present document contains all common technical requirements for emission and immunity;

- separate parts cover product related specific marine radio equipment test conditions, test arrangements,

performance criteria, normal test modulation, etc. Further work may be underway in the development of

- one new clause has been added to each of the specific radio parts of the present document entitled "Special

conditions", if appropriate. This clause contains any deviation from the common requirements set out in the

The present document contains the common requirements for marine radio communications equipment and associated

The provisions of the present document apply to marine radio equipment not covered in the scope of the Council

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, 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

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:

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

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

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
