Paper Abstract

Instead of natural exposing tests in atmosphere environment, we use artificial accelerated weathering apparatus to simulate solar radiation in ageing tests. Xenon arc lamps are most widely used to simulate spectral distribution of the sun in chambers. According to JJF1525-2015 Calibration Specification for Irradiance of Artificial Accelerated Weathering Apparatus of Xenon Arc Lamp, there are three methods to detect the irradiance: radiometer method, spectroradiometer method and standard lamp method. In this paper, we compare three methods and focus on the spectroradiometer method. Because different wavelength ranges need different radiometers, the best method to calibrate the irradiance in ageing tests is spectroradiometer method. By experiments, we verify the irradiance correspondence between 300nm~400nm and 340nm or 420nm to test the accuracy of spectroradiometer. We also study the factors affecting the irradiance calibration by spectroradiometer. At last we conclude that spectroradiometer is more suitable for irradiance calibration in different ageing tests and provide guidance for daily calibration.
