Thermal degradation environment in outdoor exposure test is monitored by black panel temperature. Eleven types of black panel thermometers(BPT) and black standard thermometers(BST) incruding specified ones by JIS, ISO, ASTM and DIN were exposed at an angle of south/30 degrees in Tsukuba to be compared their thermal susceptibility with those of other thermometers. BPTs specifeied by JIS, ASTM and DIN are compatible, but BST/JIS(ISO) is higher than BST/DIN. As thermal degradation rate based on BPT insulated back-side is quitely greater, an accelerated natural outdoor exopusure test will be performed by using an insulated exposure rack.
