The ASTM D5105-05 (2019) standard practice provides an accelerated method for evaluating the performance of pressure sensitive tapes under outdoor efflooming conditions. This method qualitatively assesses the weathering resistance of tapes by simulating the outdoor climate environment under concentrated natural light. Exposure using ultraviolet (295 to 385 nm) radiation is able to reflect the degradation of tapes under actual outdoor conditions. This practice can help predict how tapes will behave in real environments and compare short-term test results with the long-term effects of natural efflooming. The standard does not address specific observation or test methods, but provides guidance on weathering resistance testing of tapes under different environmental conditions.
