ACCELERATED LIGHT EXPOSURE IN THE XENOTEST

TESTS OF POLYSTYRENE FILM AND RIGID AND PLASTICIZED POLYVINYL CHLORIDE (PVC) UNDER LIGHT FROM AN AIR-COOLED XENON LAMP FILTERED WITH PREAGED GLASS ARE DESCRIBED. COMPARISON OF OUTDOOR EXPOSURE AND THE XENOTEST RESULTS INDICATE AN ACCELERATION OF 10-FOLD IN DECREASE OF IMPACT STRENGTH FOR PLASTICIZED PVC IN THE LABORATORY TEST AND 20-FOLD FOR THE RIGID. POLYSTYRENE FILM EXPOSED TO LIGHT ONLY IN THE XENO TEST DEVIATED IN DEGRADATION BEHAVIOR AS INDICATED BY CHANGE IN LIGHT TRANSMISSION CHARACTERISTICS FROM THAT OBSERVED IN A SAMPLE WEATHERED OUTDOORS, WHICH EFFECT IS ATTRIBUTED TO THE INFLUENCE OF THE HUMIDITY.
