ETSI ETSI EN 300 019-1-5 V2.1.4 (2003-04) 5 1 Scope The present document defines the classes of environmental conditions and their severities to which equipment may be exposed in ground vehicles. Only severe conditions, which may be harmful to the equipment, are included. The severities specified are those which will have a low probability of being exceeded; generally less than 1 %. The present document applies to equipment when in use and permanently or temporarily installed in ground vehicles. 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.

ETSI ETSI EN 300 019-1-5 V2.1.4 (2003-04) 6 4 Environmental classes The classes shown in parentheses, e.g. (5S1), may be selected for special applications. 4.1 Class 5.1: Protected installation This class is a combination of classes 5K2/5B2/5C2(5C3)/5F1(5F2)/5S2(5S1)/5M2 or 5M3 in IEC 60721-3-5 [2]. This class applies to equipment in vehicles used at weatherprotected and heated locations covered by world-wide open-air climates excluding extremely warm dry climates. At non-weatherprotected locations this class applies to equipment in ventilated compartments and in the engine compartments of vehicles powered by electric motors in climatic conditions with normal rain intensities but excluding extremely cold, cold, cold temperate and extremely warm dry climates. NOTE 1: For some environmental parameters (low air temperature, high air temperature) this class also covers externally mounted equipment. NOTE 2: A survey of applications in different climates is given in Annex A. Climatic conditions for different areas are defined in IEC 60721-2-1 [3]. This class applies to: - equipment subjected to heat from heating elements and solar radiation through windows. The vehicle may be moved between cold, non-weatherprotected and warm, weatherprotected conditions. The equipment may also be subjected to dripping water and conditions of wet mounting surfaces. Engine compartments may be subjected to the ingress of water and snow; - areas and conditions where mould growth and attacks by animals, except termites, may occur; - equipment internally mounted in partly open compartments and in engine compartments which may be subjected to the ingress of road salts; - locations with normal levels of contaminants experienced in urban areas with industrial activities scattered over the whole area and/or with heavy traffic; NOTE 3: In areas with industrial sources emitting high quantities of chemical pollutants either special precautions must be taken or the special IEC chemical class 5C3 must be chosen. - compartments where contaminating fluids are not expected; NOTE 4: If the equipment is exposed to contaminating fluids either the special precautions must be taken or the special IEC class 5F2 must be chosen. - equipment not protected from sand and dust on vehicles not used in desert areas. NOTE 5: In a vehicle cab which is mainly protected from sand the special IEC class 5S1 may be chosen. Class 5.1 also includes one of the following mechanical conditions as appropriate: - Class 5M2: All types of road vehicles used in areas with well-developed road systems except tracked vehicles, motorcycles, scooters and other vehicles with low mass. The equipment can be mounted on surfaces which may be subjected to flying stones. The equipment may be mounted on passenger car instrument panels to which high frequency vibrations from the engine, or from other parts connected to the engine, may be transmitted. This class also applies to fork lift trucks and to trains with soft suspension and shock reducing buffers; - Class 5M3: All types of road vehicles in areas without well-developed road system, tracked vehicles, self-propelled machines, overland vehicles, motorcycles, scooters and other vehicles with low mass. The equipment may be mounted on instrument panels to which high frequency vibrations from the engine, or from other parts connected to the engine, may be transmitted. This class also applies to trains with hard suspension. Externally mounted equipment may be directly hit by flying stones. ETSI ETSI EN 300 019-1-5 V2.1.4 (2003-04) 7 NOTE 6: The proper IEC class, 5M2 or 5M3, shall be chosen according to the expected installation and use of the equipment. 4.2 Class 5.2: Partly protected installation This class is a combination of classes 5K3/5B2/5C2(5C3)/5F1(5F2)/5S2(5S1)/5M2 or 5M3 in IEC 60721-3-5 [2]. In addition to conditions in class 5.1, class 5.2 applies to equipment in vehicles used at non-weatherprotected locations in climatic conditions with normal rain intensities but excluding extremely cold, cold and extremely warm dry climates. This class also applies to internally mounted equipment in heated compartments, after a warm-up period, and to equipment in engine compartments of vehicles powered by electric motors in general open-air climates. NOTE 1: A survey of applications in different climatic conditions is shown in annex A. Climatic conditions for different areas are defined in IEC 60721-2-1 [3]. This class applies to: - equipment in compartments with wet surfaces and subjected to solar radiation. The equipment may also be subjected to direct solar radiation and rain; - areas and conditions where mould growth, attacks by animals but except termites, may occur; - equipment either externally mounted or internally mounted in partly-open compartments. The equipment may be subjected to the ingress of road salt or splashing water; - locations with normal levels of contaminants experienced in urban areas with industrial activities scattered over the whole area and/or with heavy traffic; NOTE 2: In areas with industrial sources emitting high quantities of chemical pollutants either special precautions shall be taken or the special IEC class 5C3 shall be chosen. - compartments where contaminating fluids are not expected; NOTE 3: If the equipment is exposed to contaminating fluids either special precautions shall be taken or the special IEC class 5F2 shall be chosen. - equipment is not protected from sand and dust on vehicles not used in desert areas. NOTE 4: In a vehicle cab which is mainly protected from sand the special IEC class 5S1 may be chosen. Class 5.2 also includes one of the following mechanical conditions as appropriate: - Class 5M2: all types of road vehicles used in areas with a well-developed road system, except tracked vehicles, motorcycles, scooters and other vehicles with low mass. The equipment can be mounted on surfaces which may be subjected to flying stones. The equipment may be mounted on passenger car instrument panels to which high frequency vibrations from the engine, or from other parts connected to the engine, may be transmitted. This class also applies to fork lift trucks and trains with soft suspension and shock reducing buffers; - Class 5M3: All types of road vehicles in areas without a well-developed road system, tracked vehicles and self-propelled machines, overland vehicles, motorcycles, scooters and other vehicles with low mass. The equipment may be mounted on instrument panels to which high-frequency vibrations from the engine, or from other parts connected to the engine, may be transmitted. This class also applies to trains with hard suspension. Externally mounted equipment may be directly hit by flying stones. NOTE 5: The proper mechanical IEC class, 5M2 or 5M3, shall be chosen according to the expected installation and use of the equipment.
