Abstract:
The ozone resistance of a number of SBR specimens containing different sunproofing waxes has been studied under various conditions in the ozone chamber and outdoor weathering. The study showed that a direct relationship exists between ozone resistance and the temperature at the time of initial exposure. The observations noted for specimens exposed outdoors during warmAND COLD WEATHER CORRELATED WITH ACCELERATED OZONE DATA AT SIMILAR TEMPERATURES. On the basis of these studies, a tentative accelerated test is proposed, consisting of exposing dumbbell specimens at 20 per cent elongation under constant load at 50 to 60 F and 100 to 120 F and 50 pphm of ozone concentration for a period of 7 days.
