Only

20、 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 mounted for stationary use including periods of erection work, down time

21、, maintenance and repair at non-weatherprotected locations defined in clause 5. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

ETSI ETSI EN 300 019-1-4 V2.2.1 (2014-04)63 Definitions For the purposes of the present document, the following terms and definitions apply: absolute humidity: mass of water vapour in grammes w

29、hich is associated with one cubic metre of dry air in an air/water vapour mixture non-weatherprotected location: location at which the equipment is not protected from direct weather influences relative humidity: ratio of the partial pressure of the water vapour in moist air at a given temperature, t

30、o the partial pressure of the water vapour in saturated air at the same temperature stationary use: use of the equipment mounted firmly on the structure, or on mounting devices, or it is permanently placed at a certain site NOTE: It is not intended for portable use - but short periods of handling du

31、ring erection works, down time, maintenance and repair at the location are included. 4 Environmental classes The classes shown in parentheses, e.g. (4C3), may be selected for special applications. These classes shall apply to a non-weatherprotected location. These classes shall apply to locations: -

32、 which are directly exposed to an open-air climate, including solar radiation, movement of the surrounding air, precipitation and water jets; splashing water; - where mould growth, or attacks by animals but excluding termites, may occur; - with normal levels of contaminants experienced in urban area

33、s with industrial activities scattered over the whole area and/or with heavy traffic. It also applies to coastal areas; NOTE 1: At locations in the immediate neighbourhood of industrial sources with chemical emissions either special precautions should be taken or a special chemical class should be c

34、hosen. - in areas with sand or dust sources, including urban areas; NOTE 2: At locations in geographical areas with wind-driven sand or dust in air special precautions should be taken or a special class for mechanically active substances should be chosen. - where transmitted vibrations are experienc

35、ed from machines or passing vehicles. Higher level shocks may be experienced e.g. from adjacent machines. NOTE 3: More severe mechanical conditions are to be expected for equipment intended for public use. Special requirements should be stated for such equipment, e.g. protection against vandalism. I

36、f earthquake conditions can be expected, the conditions stated in clause 5.6 apply. Two groups of classes are considered: - Classes 4.1 and 4.1E apply to general climatic conditions - applies to climatic conditions in most of Europe. - Classes 4.2L and 4.2H apply to extreme climatic conditions. Thes

37、e classes should be considered only in locations with extreme climates - applies to extremely cold or warm climatic conditions world-wide. ETSI ETSI EN 300 019-1-4 V2.2.1 (2014-04)74.1 Class 4.1: Non-weatherprotected locations Class 4.1 applies to most of Europe. For Class 4.1E see note in clause 4.

38、2. Class 4.1 is a combination of classes 4K2/4Z5/4Z7/4B1/4C2(4C3)/4S2/4M5 in IEC 60721-3-4 i.2 and the environmental conditions are given in clause 5. It ranges from mild warm dry to cold temperate. The climatogram is shown in figure 1. -60-50-40-30-20-10010203040500 10203040506070809010Relative Air
