5、nces Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement international or European publications referred to in this

A British Standard does not purport to include all the necessary provisions of a contract. Users
7、 of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

19、BSI 04-1999 3 1 Scope This standard specifies a method of determining the effects of simulated solar radiation on elements of connection at ground level. It shall be used together with EN2591. 2 Normative references This European Standard incorporates by dated or undated reference provisions from ot
20、her publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment o
21、r revision. For undated references the latest edition of the publication referred to applies. EN 2591, Aerospace series Elements of electrical and optical connection Test methods General.

23、ens shall be prepared according to the technical specification. The test shall be carried out on unmated specimens. 3.2 Unless specified in the technical specification, the following details shall be stated: mounting method, type of cable and definition of specimen wiring; orientation of specimens w
24、ith respect to the radiation source; air flow rate; humidity rate; initial measurements and requirements (ifapplicable); method according to EN2591-206 and insulation resistance value; method according to EN2591-207 and voltage value; final measurement. 4 Apparatus Suitable precautions shall be take
25、n for personnel protection throughout the test. 4.1 Test chamber It shall be capable of producing an irradiance of(1,12 0,10) kW/m 2 . The surface of the radiating source shall be a minimum of 125% of the specimens projected surface to ensure irradiation of the entire exposed surface of the specimen
26、. The irradiance value shall include any radiation reflected from the test chamber and received by the specimens. It shall not include infrared radiation with a wavelength greater than 3 4m emitted by the test chamber. The test chamber shall be capable of maintaining the specified conditions of temp
27、erature, air flow and humidity. The temperature within the test chamber shall be measured (with adequate shielding from radiated heat) at a point or points in a horizontal plane 0mm to 50mm below the prescribed irradiation measurement plane. This measurement shall be carried out at half the distance
28、 between the specimen and the chamber walls or at 1m from the specimen, when this distance is smaller. 4.2 Irradiance The irradiance shall have the spectral energy distribution shown in the Table 1.

30、e specimens shall be installed in a test setup of known thermal conductivity. They shall be spaced from other specimens to avoid shielding effects and shall be orientated as specified. 5 Method 5.1 Initial measurements and requirements (ifapplicable) They shall be carried out as specified. 5.2 Proce
31、dure The specimens shall be exposed for 16d to the irradiation. The temperature within the test chamber shall be maintained at (55 2) C. On completion of exposure, the specimens shall be mated and submitted to tests EN2591-206 and EN2591-207, the temperature being maintained at(55 2) C. 5.3 Final me
