24、requirements. These tests are not reliability tests or lifetime tests. The severities of testing in EN 300 019-2-1 to 2-8 3 are closely correlated with the characteristic severities of the environmental classes in EN 300 019-1-1 to 1-8 2. The transformation has been made taking into account failure
25、consequences, performance requirements and the graded test severities in IEC 60068-2 5 test methods. In EN 300 019-2-1 to 2-8 3, “moderate failure consequences“ and “normal performance requirements“ shall be taken as standards, unless otherwise stated (see also TR 100 035 1). In order to satisfy the
26、 environmental resistibility requirements, EN 300 019-2-1 to 2-8 3 detail the severities and methods used. In many cases these conditions are different from those shown in EN 300 019-1-1 to 1-8 2 and for some parameters no testing is recommended. Where conditions have been changed, this is done in o
27、rder to: - produce the effect of the environment rather than attempt to reproduce the actual physical environmental conditions; and/or - enable standard testing to IEC 60068-2 5; and/or - recognize that the given characteristic severity relates to a condition with a very low probability of occurrenc
28、e. Where no test is specified: - other specified tests are considered to be more severe and cover that parameter; and/or - the condition is benign and consequently does not require testing. However certain product specifications may require additional testing; and/or - the condition is a valid one,
29、but no standard test method exists; and/or - the condition is considered when choosing components and materials. The mechanical test severities given may deviate from the characteristic severities and may even be split into several test alternatives, taking into consideration equipment mass. The met
30、hod given may also be different. This does not invalidate the verification because: - depending on the equipment category, size, installation method and location inside the premises, the probable stresses are different within the class; - usually only one combination of several existing complex mech
31、anical stresses are given as a characteristic. Therefore, tests with different severities and methods can serve as verification and reveal the same failure mechanisms. In meeting the test requirements shown in EN 300 019-2-1 to 2-8 3, the equipment shall be deemed to comply with the resistibility re
32、quirements shown in EN 300 019-1-1 to 1-8 2. It is emphasized that performance requirements and the individual failure criteria which apply to a specific equipment shall be included in the relevant product specification. In particular, if relevant, the distinction between normal and reduced performa
33、nce and between intermittent function and cessation of function should be precisely defined. The classifications given in EN 300 019-1-1 to 1-8 2 and the test severities given in EN 300 019-2-1 to 2-8 3 do not cover any microenvironment caused by installing one equipment inside another, e.g. several
34、 sub-racks installed inside one miscellaneous rack. In such cases the applicable conditions shall be agreed between vendor and buyer. In some cases test severities have been chosen which are not IEC preferred values, e.g. in order to stay within the prescribed limits of a climatogram. ETSI ETSI EN 3
35、00 019-2-0 V2.1.2 (2003-09) 7 5 Users guide 5.1 Test specifications and the states of test item The relevant environmental test programme shall specify whether the test item is powered-up and whether it is in-use during each phase of the tests. Two states of test item are usually required. These are
36、 the equipments “not in-use“ and “in-use“ states where: - “not in-use“ is normally the condition applicable to storage and transportation (for which the test programme shall specify if the equipment is to be in its packaging or not); - “in-use“ is normally the condition of the equipment in its worki
37、ng environment (for which the test programme shall specify the equipments performance criteria, heat dissipation, failure consequences, etc.). 5.1.1 In-use tests The required performance before, during and after the test shall be specified in the product specification. Input and load conditions of t
38、he equipment shall be chosen to obtain full utilization of the equipment under test. The dissipation shall be maximized by selection of supply power and load conditions, except for the steady-state-low-temperature test, where it shall be minimized. The tests shall be conducted in accordance with IEC
39、 60068-2 5, unless otherwise stated in Part 2 of this EN 300 019-2-1 to 2-8 3. However, in all “in-use“ tests, the equipment under test shall remain in its operational state with the exception of the cold test, in which the equipment will not be powered-up until temperature stabilization has been ac
40、hieved. The above operational conditions form a deviation from the conditioning requirements of IEC 60068-2-2 5. 5.1.2 Not in-use tests The test specifications corresponding to storage and transportation may call for the same or different test severities. The relevant environmental test programme sh
41、all describe the final compilation, where states of test item, performance requirements and failure consequences have been taken into account. 5.2 Selection of tests and test severities In EN 300 019-1-1 to 1-8 2, alternative characteristic severities for certain parameters may be chosen as special
42、requirements in the environmental class. These special requirements shall be described in the relevant product specification and noted also in the test specification. Some special test requirements may also exist. Usually they are based on the simultaneous combined effect of parameters causing simil
43、ar stresses to the equipment. Information about the combined effect of air temperature and solar radiation and the cooling effect of heat radiation are given in IEC 60721-2-4 4. The effect of surface colour and roughness on reflection of light and emission of heat are given in IEC 60068-2-5 5. For e
44、ach environmental parameter all test severities in the chosen classes for storage, transportation and in-use should be considered and the relevant severity or severities should be chosen for the test. Non-relevant tests should be deleted. Experience from earlier tests may justify deletion of some te
45、sts. ETSI ETSI EN 300 019-2-0 V2.1.2 (2003-09) 8 6 Topics on making a test programme The various aspects to be considered when formulating a test programme are discussed in TR 100 035 1, clause 6.4.3: - the programme is a result of co-operation between environmental experts, test engineers and equip
46、ment development engineers; - an efficient way to perform the complete test programme requires engineering experience (knowledge about materials, components, construction and design), common sense and realistic judgements; - considerations on testing costs, technology of equipment and life cycle cos
47、ts shall be included; - failure consequences other than moderate and/or degraded performance requirements can be taken into account by choosing, for example, a larger test sample or by modification of test severities. For further information see TR 100 035 1. Clauses 6.1 to 6.3 describe the most imp
48、ortant items. 6.1 Environmental resistibility requirements The environmental class defines the overall requirements. The resistibility requirement for a given class is valid whether or not a test is included in the test specification programme. The test specifications give the test severities for th
49、e verification of the resistibility. The equipment under test shall be identical to that placed on the market. For storage and transportation tests, if the equipment is normally packaged then it shall be tested in its packaging. For “in-use“ tests, if the equipment is specially mounted (e.g. in a protective enclosure or with shock absorbing buffers), then it shall be tested as such. 6.2 Test programme For certain reasons (e.g. economic) the test programme can have several tests in sequence on one single equipment.
