National transposition dates Date of latest announcement of this EN (doa): 31 July 2003 Date of latest publication of new National Standard or endorsement of this EN (dop/e): 31 January 2004 Date of withdrawal of any conflicting National Standard (dow): 31 January 2004 ETSI ETSI EN 300 019-1-6 V2.1.4 (2003-04) 5 1 Scope The present document defines classes of environmental conditions and their severities to which telecommunication equipment may be exposed. The severities specified are those which will have a low probability of being exceeded; generally less than 1 %. The present document applies to equipment designed principally for maritime use. Conditions of use vary significantly in relation to the size of the vessel and the function for which it was designed. The reader should ensure that the relevant classes are chosen to suit this particular application. The present document covers the following types of vessel: - vessel propelled by mechanical means, including offshore units; - vessel not propelled by mechanical means, including sailing boats and life rafts. The classes defined apply to all sizes of vessel from pleasure craft to trawlers, ferry boats, icebreakers and cargo ships including tankers. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

NOTE 2: Totally weatherprotected location: direct weather influences are totally excluded. 4 Environmental classes 4.1 Class 6.1: totally weatherprotected locations This class is a combination of classes 6K1/6B1/6C1/6S1/6M3 in IEC 60721-3-6 [2]. This class applies to equipment installed in totally weatherprotected, heated and ventilated locations following warm-up on board engine-powered vessels but excluding refrigerated cargo spaces, machinery spaces and locations containing equipment dissipating considerable amounts of heat. This class does not cover Warm Damp and Warm Damp Equable climates. NOTE: Climatic conditions for different areas are defined in IEC 60721-2-1 [3]. This class applies to: - equipment which is not exposed to heat radiation from adjacent equipment, heating elements or to solar radiation through glass or transparent materials; - installations on board vessels operating in areas without particular risk of attack by flora or fauna. It also covers other vessels where the installations are located in compartments of such construction that mould growth and attacks by animals are unlikely; - totally weatherprotected installations which are not subjected to salt mist, engine exhausts or emissions from nearby industrial sources; - installations protected from sand, dust and ingress of soot; - installations on board engine-powered vessels of all sizes. 4.2 Class 6.2: partly weatherprotected locations This class is a combination of classes 6K4/6B2/6C3/6S2/6M3 or 6M4 in IEC 60721-3-6 [2]. This class applies, depending on the mechanical class chosen, to equipment installed in any location on board engine-powered vessels - excluding refrigerated cargo spaces. The class applies in all climates with the exception of Cold climates and areas with abnormal rain intensities and hurricanes. The equipment may occasionally be subjected to heavy seas. (See the note to clause 4.1). This class applies to: - equipment which is subjected to direct solar radiation, to considerable heat dissipation from boilers, engines etc., to rain and water jets. The equipment may be connected to wet surfaces; - non-protected installations on board vessels operating in areas where mould growth and attacks by animals may occur; - non-weatherprotected installations on board vessels operating close to industrial areas with considerable air pollution emissions. Salt mist and exposure to engine exhausts are included; - all installations where sweeping of dusty decks may take place. It also covers locations subject to emissions from boiler exhausts (e.g. soot, acid, etc.). Non-weatherprotected installations on board vessels operating close to sand deserts are not covered; ETSI ETSI EN 300 019-1-6 V2.1.4 (2003-04) 7 - class 6M3: installations on board engine-powered vessels of all sizes but excluding equipment connected directly to reciprocating types of machinery. Equipment connected directly to loading systems, container guides, cranes and installations in dredgers are included; - class 6M4: all installations on board engine-powered vessels of all sizes including equipment connected directly to reciprocating types of machinery. NOTE: The proper mechanical IEC class 6M3 or 6M4 shall be chosen according to the expected installations and use of the equipment. 4.3 Class 6.3: non-weatherprotected locations This class is a combination of classes 6K5/6B2/6C3/6S2/6M3 or 6M4 in IEC 60721-3-6 [2]. This class applies, depending on the mechanical class chosen, to equipment installed in any location on board engine-powered vessels, including refrigerated cargo spaces. This class applies in all climates including areas with abnormal rain intensities and hurricanes. The equipment may also be subjected to heavy seas. (See the note to clause 4.1.)

Equipment may, however, be left unprotected on board vessels which are temporarily laid-up in harbour during the coldest period of the year. In such instances equipment, in the non-operational state, may have to withstand temperatures down to -55°C. In exceptional circumstances in inland waterways vessels may also navigate when temperatures are below -40°C. NOTE 2: The freezing-point may be lower than 0°C due to presence of salt or pollution, etc. NOTE 3: Surface temperatures refer to hot parts to which the equipment may be attached. More extreme surface temperatures can exist, for instance on machines, and may have to be considered. NOTE 4: The equipment is assumed to be subjected to a rapid decrease of temperature only (no rapid increase). The figure for water content applies to temperatures down to the dew-point. At lower temperatures the relative humidity is assumed to be approximately 100 %. 5.2 Biological conditions Table 2: Biological conditions for environmental classes 6.1 to 6.3 Classes Environmental parameter Unit 6.1 6.2 and 6.3 a) Flora none negligible Presence of mould, fungus, etc. b) Fauna none negligible Presence of rodents and other animals harmful to equipment.
