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
