The present document is part 1, sub-part 2 of a multi-part deliverable covering the classification of environmental conditions and

15、environmental tests for telecommunications equipment, as identified below: Part 1: “Classification of environmental conditions“: (see note 1) Sub-part 0: “Introduction“; Sub-part 1: “Storage“; Sub-part 2: “Transportation“; Sub-part 3: “Stationary use at weatherprotected locations“; Sub-part 4: “Stat

16、ionary use at non-weatherprotected locations“; Sub-part 5: “Ground vehicle installations“; Sub-part 6: “Ship environments“; Sub-part 7: “Portable and non-stationary use“; Sub-part 8: “Stationary use at underground locations“; Part 2: “Specification of environmental tests“ (see note 2). NOTE 1: Speci

17、fies different standardized environmental classes covering climatic and biological conditions, chemically and mechanically active substances and mechanical conditions during storage, transportation and in use.

18、verities and test methods for the different environmental classes. National transposition dates Date of adoption of this EN: 21 April 2014 Date of latest announcement of this EN (doa): 31 July 2014 Date of latest publication of new National Standard or endorsement of this EN (dop/e): 31 January 2015

19、 Date of withdrawal of any conflicting National Standard (dow): 31 January 2015 ETSI ETSI EN 300 019-1-2 V2.2.1 (2014-04)51 Scope The present document defines classes of environmental conditions and their severities to which telecommunication equipment may be exposed. The severities specified are th

20、ose which will have a low probability of being exceeded; generally less than 1 %. The present document applies to equipment being transported from one place to another after being made ready for dispatch from the manufacturers works. The most commonly used methods of transportation have been taken i

21、nto account, i.e. ground, water and air transport. Loading and unloading as well as temporary storage, have been included. Where the equipment is packaged the environmental conditions apply to the packaged equipment. NOTE: Normal transportation time is considered to be 30 days or less. Where the tot

22、al transportation time exceeds 30 days then additional storage or packaging precautions should be considered. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

ETSI ETSI EN 300 019-1-2 V2.2.1 (2014-04)63 Definitions For the purposes of the present document, the following terms and definitions a

28、pply: absolute humidity: mass of water vapour in grammes which is associated with one cubic metre of dry air in an air/water vapour mixture non-weatherprotected location: equipment, packaged or unpackaged, is not protected in any way from the environment relative humidity: ratio of the partial press

29、ure 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 weatherprotected location: location at which the equipment is protected from direct weather influences NOTE: Totally weatherprotected location: the equipm

30、ent, packaged or unpackaged, is contained within an enclosure which affords some protection from the environment, ranging from a temperature controlled container to a waterproof cover placed over the equipment. Ventilation ranges from controlled air flow to the raising of part of a waterproof cover

31、to allow for natural air flow. 4 Environmental classes Three different environmental classes have been defined. Classes 2.1 and 2.2 are special classes relating to low temperature and less severe mechanical conditions. Class 2.3 is the normal class for transportation of equipment. 4.1 Class 2.1: Ver

32、y careful transportation Class 2.1 is a combination of classes 2K3/2B2/2C2/2S2/2M1 in IEC 60721-3-2 i.2. This class shall apply to transportation where special care has been taken e.g. with respect to low temperature and handling. The conditions covered include transportation in unventilated enclosu

33、res and in non-weatherprotected conditions with restrictions on the general open-air climates, excluding cold and cold temperate climates. transportation by air only covers equipment carried in heated, pressurised holds. NOTE: A survey of applications in different climates is shown at annex A. Clima

34、tic conditions for different areas are defined in IEC 60721-2-1 i.3. This class shall apply to transportation: - where the equipment may be moved between cold, non-weatherprotected and warm, weatherprotected conditions. It may for short periods be exposed to direct solar radiation, precipitation and

35、 splashing water. The equipment may be placed on a wet floor and inside an enclosure which is subjected to sunshine and rain etc. Non-weatherprotected exposure does not include exposure to sea waves. The equipment may be placed close to heating elements; - in areas and conditions where mould growth,

36、 attacks by animals, except termites, may occur; - which is non-weatherprotected (but including transport by sea where the equipment is protected against sea waves) in areas with normal industrial activities excluding those where large quantities of chemical pollutants are emitted; - which is non-we

37、atherprotected, as well as weatherprotected and where sweeping of dusty floors is taken into account. Transportation in sand desert areas is not included; - in aircraft, lorries and air-cushioned trucks and trailers in areas with well-developed road systems. Only mechanical loading and unloading is

38、included. No risk of dropping is taken into account. The mechanical conditions given apply to equipment placed on the floor of the compartment in which it is transported. ETSI ETSI EN 300 019-1-2 V2.2.1 (2014-04)74.2 Class 2.2: Careful transportation Class 2.2 is a combination of classes 2K3/2B2/2C2

39、/2S2/2M1 in IEC 60721-3-2 i.2. This class shall apply to transportation where special care has been taken e.g. with respect to low temperature and handling. Class 2.2 covers the conditions of class 2.1. In addition class 2.2 includes transportation in all types of lorries and trailers in areas with

40、well-developed road systems. It also includes transportation by ship and by train with specially designed, shock-reducing buffers. Manual loading and unloading of up to 20 kg is included. 4.3 Class 2.3: Public transportation Class 2.3 is a combination of classes 2K4/2B2/2C2/2S2/2M2 in IEC 60721-3-2

41、i.2. This class shall apply to transportation, where no special precautions have been taken. The conditions covered include transportation in unventilated enclosures and in non-weatherprotected conditions with restrictions on the general open-air climates, excluding cold climates. Transportation by

42、air covers equipment carried in heated, pressurised holds. NOTE: A survey of applications in different climates is shown in annex A. Climatic conditions for different areas are defined in IEC 60721-2-1 i.3. Class 2.3 covers the conditions of classes 2.1 and 2.2. In addition class 2.3 has a lower col

43、d-temperature limit. Continuous or repeated solar radiation, precipitation and splashing of water may occur. Class 2.3 also includes all types of transport in areas without well-developed road systems. Rough handling is included. ETSI ETSI EN 300 019-1-2 V2.2.1 (2014-04)85 Environmental conditions 5

NOTE 2: The high temperature of the surface of a product is influenced by the surrounding air temperature, given here, and the

49、solar radiation defined below. NOTE 3: A direct transfer of the product between the two given temperatures is presumed. NOTE 4: The product is assumed to be subjected to a rapid decrease of temperature only (no rapid increase). The figures of water content apply to temperatures down to the dew-point; at lower temperatures the relative humidity is assumed to be approximately 100 %. NOTE 5: The figure indicates the velocity of water and not the height of water accumulated. NOTE 6: Occurrence of condensation. NOTE 7: For short duration only. 5.2 Biol
