GB/T 3681-2011 specifies three exposure test methods for daylight climate aging of plastics: natural daylight exposure (Method A), post-Glass filtrated daylight exposure (Method B) and Fresnel otoscope accelerated daylight exposure (Method C). The standard aims to evaluate the aging performance of plastics under different Light spectrum conditions, taking into account factors such as daylight radiation, moisture, etc. Method C provides accelerated exposure conditions and is suitable for evaluating performance changes in extreme environments. The standard also includes requirements for test devices and operating methods.
