29、nded 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):

The climatogram is shown in figure 1 in cl
32、ause 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
33、 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-con
34、trolling 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 drau
35、ghts 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 gr
36、owth 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 o
37、f 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; - worksh
38、ops for electronic assemblies and other electrotechnical products; - telecommunication centres; - storage rooms for valuable and sensitive products.

42、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-
43、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. thro
44、ugh 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
45、 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;
46、- 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

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 temp

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
