Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Environmental Engineering (EE). The present document is part 1, sub-part 0 of a multi
13、-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 0: “Introduction“; Sub-part 1: “Storage“; Sub-part 2: “Transportation“; Sub-part 3:
14、“Stationary use at weatherprotected locations“; Sub-part 4: “Stationary 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: “
15、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. Part 2 specifies the recommended test s
16、everities and test methods for the different environmental classes. National transposition dates Date of adoption of this EN: 5 September 2003 Date of latest announcement of this EN (doa): 31 December 2003 Date of latest publication of new National Standard or endorsement of this EN (dop/e): 30 June
17、 2004 Date of withdrawal of any conflicting National Standard (dow): 30 June 2004 ETSI ETSI EN 300 019-1-0 V2.1.2 (2003-09) 5 1 Scope The purpose of the present document is to select class(es) of environmental conditions and their severities to which equipment may be exposed. Only severe conditions,
18、 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 purpose of the present document is to form a general overview of Part 1. TR 100 035 1 should be used in conjunction with all part
19、s of EN 300 019 series. It gives an introduction to the main concepts of environmental engineering, the purpose and use of environmental classes and the corresponding test philosophy. 2 References The following documents contain provisions which, through reference in this text, constitute provisions

23、ts“. 3 Definitions For the purposes of the present document, the following terms and definitions apply: environmental class: systematic representation of the environment for a family of locations with “similar properties“ NOTE: This means that the detailed description of the class may be envisaged a
24、s an envelope around a group of related environmental conditions. The class itself may not be considered directly as a typical example. A class is composed of the most significant single factors, termed environmental parameters, selected from those factors which are assumed to influence equipment pe
25、rformance. Full descriptions of each class are included in the appropriate parts of EN 300 019-1 2. environmental condition: physical, chemical or biological condition, external to an equipment, to which it is subjected at a certain time. NOTE: Environmental conditions are generally composed of envi
26、ronmental conditions appearing in nature and environmental conditions generated by the equipment itself or by external sources. environmental factor: physical, chemical or biological influence which, either singly or in combination with other influences, produces an environmental condition (e.g. hea
27、t, vibration) ETSI ETSI EN 300 019-1-0 V2.1.2 (2003-09) 6 environmental parameter: one or more physical, chemical or biological properties characterizing an environmental factor (e.g. temperature, acceleration) EXAMPLE: The environmental factor vibration is characterized by the parameters: type of v
28、ibration (sinusoidal, random), acceleration and frequency. in-use: An equipment is in-use when it is directly operational. mobile use: An equipment is in mobile use when it is primarily intended to be installed or fixed and operated in or on, a vehicle or a ship. portable and non-stationary use: The
29、 equipment is frequently moved from place to place. During transfer there is no special packaging for the equipment. The total transfer time may amount to a significant portion of the equipments lifetime. The equipment is not permanently mounted on any structure or placed at a fixed site. The equipm
30、ent may be operated while being either in a non-stationary or in a transfer state. severity of environmental parameter: value of each quantity, characterizing the environmental parameter EXAMPLE: The severity of sinusoidal vibration is defined by values of the acceleration (m/s2) and frequency (Hz).
31、 stationary use: An 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 work, down time, maintenance and repair at the location are included. storage: T
32、he equipment is placed at a certain site for a long period, but is not intended for use during this period. If the equipment is packaged, the environmental conditions apply to the packaging protecting the equipment. transportation: phase during which the equipment is moved from one place to another
33、after being made ready for dispatch NOTE: It includes loading, unloading and temporary storage. The equipment is not in-use under these conditions. 4 Environmental classes 4.1 Purpose of classification The main purpose of environmental classification is to establish a number of “standardized“ and op
34、erational frames of reference for a wide range of applications of (telecommunications) equipment. These classes cover storage, transportation, and in-use, in typical environmental conditions.

41、eed to be selected for: - storage; - transportation; - in-use (one or more classes can be selected). NOTE 2: The example (in bold) shows possible class selections for equipment, i.e. class 1.1, class 2.3 and class 3.1. NOTE 3: Class 3.1 includes exceptional operating conditions (shown as 3.1E in tab
42、le 1 of EN 300 019-1-3 2) where reduced performance requirements are allowed. There shall be no irreversible failures when normal operating conditions has been restored. There is no separate class 3.1E. Figure 1 ETSI ETSI EN 300 019-1-0 V2.1.2 (2003-09) 8 5 Explanation of climatograms A climatogram
43、is an envelope of climatic conditions defined by the characteristic severities of these conditions. A characteristic severity is a severity which has a low probability of being exceeded (generally less than 1 %). Equipment conforming to a particular class shall function at all values within the boun
44、dary of the climatogram for that class. However, the points inside the climatogram will have different probabilities of occurrence depending on the shape of the statistical distributions of temperature and humidity. There will be an area inside the climatogram whose points will have a high probabili
45、ty of occurrence. This implies that the environment can remain for long periods in that area, but shall not remain near the boundary of the climatogram for long periods. The distribution of climatic conditions for some classes will be a natural phenomenon, while for other classes, with climate contr
46、olling systems, distribution will be partly controllable. The distribution will vary for each class and each location. Figure 2 shows a simplified symmetrical distribution.

48、esign process for producing equipment a) Suppliers, in assessing customer requirements for an item of equipment, will choose appropriate environmental classes from EN 300 019-1-1 to 1-8 2 for storage, transportation and in-use conditions for designs at the conceptual stage. b) The chosen environment
49、al classes will be included in the equipment design specification. c) A test programme will be drawn up using the chosen environmental classes to select appropriate tests from EN 300 019-2-1 to 2-8 3. d) The equipment will be tested for resistibility to the chosen environmental classes in accordance with the test programme. These environmental classes will then be quoted in the product specification. By using the above process, if the original application changes during the equipments life, then the need for further development and testing can
