Testing Procedure 1,Using the calibrated radiameter measure the irradiance at the proposed module test plane and ensure that at wavelength between 280nm and 400nm it does not exceed 250W/M2 (i.e. about five times the natural sunlight level) and that it has a uniformity of ±15% over the test plane
2,Short-circuit or attach the resistive load to the module and mount it in the test plane at the location selected , normal to the UV irradiance beam. Make sure that the module temperature sensors read 65±5oC
3,Subject the modules front side to a total UV irradiation of at least 15 KW/m2 in the wavelength range between 280nm and 400nm with at least 3%, but not more than 10% in the wavelength band between 280nm and 320nm , while maintaining the module temperature within the prescribed range
