ETSI ETSI EN 300 019-1-3 V2.2.2 (2004-07) 6 forced ventilation system: system that controls or influences climate by introducing outdoor air into the room or expelling air out of the room heating system: system that controls or influences climate by increasing the air temperature only NOTE: This can decrease the relative humidity. relative humidity: ratio of the partial pressure of the water vapour in moist air at a given temperature, to the partial pressure of the water vapour in saturated air at the same temperature stationary use: The equipment is mounted firmly on the structure, or on mounting devices, or it is permanently placed at a certain site. It is not intended for portable use - but short periods of handling during erection works, down time, maintenance and repair at the location are included. weatherprotected location: location at which the equipment is protected from direct weather influences: totally weatherprotected location (enclosed location): - direct weather influences are totally excluded, partly weatherprotected location (sheltered location): - direct weather influences are not completely excluded. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: RS Response Spectrum ZPA Zero Period Acceleration 4 Environmental classes The classes shown in parentheses, e.g. (3C1), may be selected for special applications. 4.1 Class 3.1: Temperature-controlled locations Class 3.1 is a combination of classes 3K3/3Z2/3Z4/3B1/3C2(3C1)/3S2/3M1 in IEC 60721-3-3 1. The climatogram is shown in figure 1 in clause 4.1. Seismic environment: zone 4 as defined in IEC 60721-2-6 3. Option zone 4 (modified Mercalli scale 9): if earthquake conditions are specified by the customer, the conditions stated in clause 5.6 apply. This class applies to a permanently temperature controlled enclosed location. Humidity is usually not controlled. The climatogram is shown in figure 1. Heating, cooling, forced ventilation and humidification are used as necessary to maintain the required conditions - especially where there is a significant difference between the room environment and the external ambient. The climate-controlling systems could be periodically switched on or off but extremely high or low temperatures are prevented. This class applies to locations: - where installed equipment may be exposed to solar radiation and to heat radiation. It may also be exposed to movements of the surrounding air due to draughts in buildings. They are not subjected to condensed water, precipitation, water from sources other than rain or icing; - without particular risks of biological attacks. This includes protective measures, e.g. special product design, or installations at locations of such construction that mould growth and attacks by animals, etc. are not probable; ETSI ETSI EN 300 019-1-3 V2.2.2 (2004-07) 7 - with normal levels of contaminants experienced in urban areas with industrial activities scattered over the whole area and/or with heavy traffic; - without special precautions to minimize the presence of sand or dust, but which are not situated in proximity to sources of sand or dust; - with insignificant vibration and shock. The conditions of this class may be found in: - normal living or working areas, e.g. living rooms, rooms for general use (theatres, restaurants); - offices; - shops; - workshops for electronic assemblies and other electrotechnical products; - telecommunication centres; - storage rooms for valuable and sensitive products.

Exceptional climatic limits. Normal climatic limits: Values outside these limits have a probability of occurrence of less than 1 % . NOTE: Exceptional conditions may occur following the failure of the temperature controlling system. This is described as 3.1E in the tables but it should be noted that there is no separate class 3.1E. Figure 1: Climatogram for Class 3.1: Temperature-controlled locations 4.2 Class 3.2: Partly temperature-controlled locations This class is a combination of classes 3K5/3Z2/3Z4/3B2/3C2(3C1)/3S3/3M2 in IEC 60721-3-3 1 . Seismic environment: zone 4 as defined in IEC 60721-2-6 3. Option zone 4 (modified Mercalli scale 9): if earthquake conditions are specified by the customer, the conditions stated in clause 5.6 apply. ETSI ETSI EN 300 019-1-3 V2.2.2 (2004-07) 8 This class applies to an enclosed location having neither temperature nor humidity control. The climatogram is shown in figure 2. Heating may be used to raise low temperatures especially where there is a significant difference between the conditions of this class and the open-air climate. Building construction is designed to avoid extremely high temperatures. This class applies to locations: - where installed equipment may be exposed to solar radiation and heat radiation. They may also be exposed to movements of the surrounding air due to draughts in buildings, e.g. through open windows. They may be subjected to condensed water. They are not subjected to precipitation; - where mould growth or attacks by animals, except termites, may occur; - with normal levels of contaminants experienced in urban areas with industrial activities scattered over the whole area and/or with heavy traffic; - in close proximity to sources of sand or dust; - with vibration of low significance, e.g. for products fastened to light supporting structures subjected to negligible vibrations. The conditions of this class may be found in: - entrances and staircases of buildings; - garages; - cellars; - certain workshops; - buildings in factories and industrial process plants; - unattended equipment stations; - certain telecommunication buildings; - ordinary storage rooms for frost resistant products and farm buildings, etc. -20 -10 0 10 20 30 40 50 0102030405060708090100 Relative Air Humidity % Air Temperature °C 1 29 Absolute Air Humidity g/m3 Figure 2: Climatogram for class 3.2: Partly temperature-controlled locations ETSI ETSI EN 300 019-1-3 V2.2.2 (2004-07) 9 4.3 Class 3.3: Not temperature-controlled locations This class is a combination of classes 3K6/3Z2/3Z4/3Z7/3B2/3C2(3C1)/3S3/3M2 in IEC 60721-3-3 1. Seismic environment: zone 4 as defined in IEC 60721-2-6 3, Option zone 4 (modified Mercalli scale 9): if earthquake conditions are specified by the customer, the conditions stated in clause 5.6 apply. This class applies to a weatherprotected location having neither temperature nor humidity control. The location may have openings directly to the open air, i.e. may be only partially-weather protected. The climatogram is shown in figure 3. The climatic conditions of this class may be affected to a varying extent by the conditions of the open-air climate and the construction of the building. This class applies to locations: - where installed equipment may be exposed to solar radiation and temporarily to heat radiation. It may also be exposed to movements of the sur
