20、ls of a fibre optic device. It is intended to simulate the radiation experienced at the surface of the earth. 1.2 General description This procedure is conducted in accordance with IEC 68-2-5, test Sa. The specimen is subjected to an irradiance of 1,120 kW/+ with a prescribed spectral distribution.
21、The test includes three methods differing in the irradiation cycle times. WARNING NOTE - Intended usem of solar radiaon tests are cautioned regarding the health hazards associated wmi tests of this nature. IEC 68-2-9, clause 9 deals with this subject. 1.3 Nonnative references The following normative
22、 documents contain provisions which, through reference in this. text, constitute provisions of this part of IEC 1300. At the time of publication, the edition indicated was valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC 1300 are encouraged
23、to investigate the possibility of applying the most recent editions of the normative documents indicated below.

This results in a total irradiation of 8.96 kWh/m* per diurnal cycle and approximates the most severe natural conditions. 3.1.2 Method B A 24 h cycle, with 20 h of irradiation and 4 h of darkness, repeated as specified. This results in a total irradiation of 22.4 kWh/m* p
