Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Environmental Engineering (EE). The present document is part 1, sub-part
15、7 of a multi-part deliverable covering the classification of environmental conditions and environmental tests for telecommunications equipment, as identified below: Part 1: “Classification of environmental conditions“; Sub-part O : “Introduction“ ; Sub-part 1 : “Storage“; Sub-part 2: “Transportation
16、“; Sub-part 3: Sub-part 4: Sub-part 5: “Ground vehicle installations“; Sub-part 6: “Ship environments“; Sub-part 7: Sub-part 8: “Stationary use at weatherprotected locations“; “Stationary use at non-weatherprotected locations“; “Portable and non-stationary use“; “Stationary use at underground locati
17、ons“; Part 2: “Specification of environmental tests“. Part 1 specifies different standardized environmental classes covering climatic and biological conditions, chemically and mechanically active substances and mechanical conditions during storage, transportation and in use.

The seve
20、rities specified are those which will have a low probability of being exceeded; generally less than 1 %. The present document applies to equipment during portable and non-stationary use including periods of transfer, down time, maintenance and repair at locations defined in clauses 3 to 5. 2 Re fe r

26、vapour mixture non-weatherprotected location: location at which the equipment is not protected from direct weather influences portable and non-stationary use: equipment which may be moved frequently from place to place NOTE: The total transfer time may amount to a significant portion of the equipmen
27、ts lifetime. The equipment is not permanently mounted on any structure or placed at a fixed site. The equipment may be operating while being either in a stationary or in a transfer state. relative humidity: ratio of the partial pressure of the water vapour in moist air at a given temperature, to the
28、 partial pressure of the water vapour in saturated air at the same temperature ETSI 6 ETSI EN 300 019-1-7 V2.1.4 (2003-04) weatherprotected location: location at which the equipment is protected from direct weather influences NOTE 1 : Partly weatherprotected location (sheltered location): direct wea
29、ther influences are not completely excluded. NOTE 2: Totally weatherprotected location (enclosed location): direct weather influences are totally excluded. 4 Envi ron men ta I classes Two mechanical classes, 7M2 and 7M3, are used and cover all the environmental classes 7.1 to 7.3E. The relevant clas
30、s is determined by consideration of the expected handling, means of transfer and complete use-profile of the equipment. The special, severe, class 7M3 applies to use only in circumstances where the equipment is exposed to rough handling, severe shocks and vibration e.g. from the means of transfer or
31、 rotating machinery. The classes shown in parentheses, e.g. (7C1), may be selected for special applications. 4.1 Class 7.1 : temperature controlled locations This class is a combination of classes 7K1/722/724/7B1/7C2(7C1)/7S1/7M2 or 7M3 in IEC 60721-3-7 2. This class applies to use at, and direct tr
32、ansfer between, permanently temperature-controlled and enclosed locations. Humidity is usually not controlled. The climatogram is shown in figure 1. Heating, cooling or humidification is used, where necessary, to maintain the required conditions, especially where there is a large difference between
33、the internal climate and that open-air climate. Heating or cooling may be switched off for periods but the occurrence of extremely high or low temperatures is prevented. This class applies to use at, and transfer between, locations: - where the equipment may be exposed to solar radiation and to heat
34、 radiation. It may also be exposed to movements of the surrounding air (e.g. due to draughts in buildings through open windows) and to condensed water. It is not subjected to precipitation, or water from sources other than rain or icing; - without particular risk of biological attack. This includes
35、protective measures, e.g. special product design, or installation in locations of such construction that mould growth and attacks by animals, etc. are not probable; with normal levels of contaminants experienced in urban areas, with industrial activities scattered over the whole area andor with heav
36、y traffic; NOTE: - For long term exposure to simultaneous occurrence of several contaminants a special chemical class 7C 1 should be chosen. - without special precautions to minimize the presence of sand or dust, but which are not situated in proximity to sources of sand or dust. The mechanical clas
37、s shall be determined by reference to clause 4, “Environmental classes“. The conditions of this class may be found in, and during transfer to, normal working or living areas, e.g.: - telecommunication centres; - workshops; - offices; - storage rooms for valuable and sensitive products; - shops; - ro
38、oms for general use (theatres, restaurants, etc.); ETSI 7 ETSI EN 300 019-1-7 V2.1.4 (2003-04) - living rooms. 50 40 30 20 10 io -10 -20 n a2 s m i Eo: 7 O 10 20 30 40 50 60 70 80 90 100 Relative Air Humidity %I Figure 1 : Climatogram for class 7.1 : temperature controlled-locations Class 7.2: partl

This class applies to use at, and direct transfer between, enclosed locations having neither temperature nor humidity control. The climatogram is shown in figure
40、2. Heating may be used to raise low temperatures especially where there is a large 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 use at, and direct transfer between, locations: -
41、 where equipment may be exposed to solar radiation and heat radiation. It may also be exposed to movements of the surrounding air (e.g. due to draughts in buildings through open windows). It may be subjected to condensed water, to water from sources other than rain and to icing. It is not subjected
42、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 andor with heavy traffic; - - NOTE 1 : For long term exposure to simultaneous occurrence of s
43、everal contaminants a special chemical class 7C1 should be chosen. - in close proximity to sources of sand or dust. The mechanical class shall be determined by reference to clause 4, “Environmental classes“. The conditions of this class may be found in, and during transfer to: - certain telecommunic
44、ation buildings; - unattended equipment stations; - certain workshops; - buildings in factories and industrial process plants; - ingarages; - entrances and staircases of buildings; ETSI 8 ETSI EN 300 019-1-7 V2.1.4 (2003-04) - cellars; - - farm buildings etc. ordinary storage rooms for frost resista
45、nt products; NOTE 2: Underground spaces and manholes, etc.: class 7.2 can be used in these locations if extreme climatic conditions can be deliberately avoided. Class 8.1 conditions in EN 300 019-1-8 5 shall be considered if no control of the climatic conditions during exposure is possible. 50 40 7

47、K3/722/726/729/7B2/7C2/7S2/7M2 or 7M3 in IEC 60721-3-7 2 This class applies to use at partly weatherprotected locations in buildings of such a construction that extremely low temperatures are avoided. This class also applies to use at non-weatherprotected locations in a Warm Temperate climate and to
48、 transfer between these locations. During cold seasons non-weatherprotected use and transfer is limited. The climatogram is shown in figure 3. Climatic conditions for different areas are defined in IEC 6072 1-2- 1 3. This class applies to use at, and direct transfer between, locations: - where the e
49、quipment may be exposed to direct solar radiation, heat radiation, movement of the surrounding air, condensed water, precipitation, water from sources other than rain and icing; 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 andor with heavy traffic; - - - in close proximity to sou
