Foreword This 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 respo
15、nse to a mandate from the European Commission issued under Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of information in the field of technical standards and regulations. The present document, together with ETS 300 460, is intended to become a Harmonized Stand
16、ard, 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 as amended). Technical specifications
17、relevant to the EMC Directive are given in annex A. National transposition dates Date of adoption of this EN: Date of latest announcement of this EN (doa): Date of latest publication of new National Standard or endorsement of this EN (dop/e): Date of withdrawal of any conflicting National Standard (
18、dow): 6 February 1998 31 May 1998 30 November 1998 30 November 1998 6 EN 300 829 V1.l.l (1998-03) 1 Scope The present document covers the assessment of Inmarsat-C Global Maritime Distress and Safety System (GMDSS) and Enhanced Group Call (EGC) Ship Earth Stations, as defiied by the International Mar
19、itime Organization (IMO) to be used for Low Bit Rate Data Communications (LBRDC) in the GMDSS, in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions for the enclosure port of the radio equipment are found in the related product standard
20、 ETS 300 460 111 for the effective use of the radio spectrum. The present document specifies the applicable EMC tests, the test methods, the limits and the minimum performance criteria for Ship Earth Stations for the maritime mobile service operating in the Maritime Mobile Satellite Service (MMS S)
21、bands. The ElectroMagnetic Environment used in the present document to develop the technical specifications encompasses the ElectroMagnetic Environment on board ships as identified in EN 60945 13. The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus in m
22、aritime environments. The levels do not cover extreme cases which may occur in any location, but have a low probability of occurrence . Compliance of radio equipment to the requirements of the present document does not sign compliance to any requirements related to the use of the equipment (i.e. lic
23、ensing requirements). Compliance to the present document does not sign compliance to any safety requirements. However, it is the responsibility of the assessor of the equipment that any observations regarding apparatus becoming dangerous or unsafe as a result of the application of the tests defined
24、in the present document, are recorded in the test report. The present document is based on the consideration and guidance as given in ETR 238 12. 2 Re fe ren ces References may be made to: a) specific versions of publications (identified by date of publication, edition number, version number, etc.),

The normal temperature and humidity conditions shall be a combination of temperature and humidity within the following ranges: - temperature +15“C to +35“C - r
45、elative humidity 25 % - 75 % The normal test voltage for equipment to be connected to the AC mains, shall be the nominal mains voltage. The frequency of the test voltage shall be 50 Hz f 1 Hz. The normal test voltage for equipment to be connected to a battery, shall be the nominal voltage of the bat
46、tery (12 V, 24 V etc.). For operation from other power sources, the normal test voltage shall be declared by the manufacturer. The test configuration shall be as close as possible to normal intended use. 9 EN 300 829 V1.l.l (1998-03) If the equipment is part of a system, or can be connected to ancil
47、lary equipment, then it shall be acceptable to test the equipment while connected to the minimum representative configuration of ancillary equipment necessary to exercise the ports. Ports which in normal operation are connected shall be connected to an ancillary equipment or to a representative piec
48、e of cable correctly terminated to simulate the input/output characteristics of the ancillary equipment. RF input/output ports shall be correctly terminated. If the equipment has a large number of ports, then a sufficient number shall be selected to simulate actual operation conditions and to ensure
49、 that all the different types of termination are tested. Ports which are not connected to cables during normal intended operation, e.g. service connectors, programming connectors, temporary connectors etc. shall not be connected to any cables for the purpose of EMC testing. Where cables have to be connected these ports, or interconnecting cables have to be extended in length in order to exercise the EUT, precautions shall be taken to ensure that the evaluation of the EUT is not affected by the addition or extension of these cables.
