- 29 - ABSTRACT Pre-testing Method and Apparatus for a Weathering Test Prior to weathering test for samples, for example, plastic, fiber, or paint, the samples are exposed to ultraviolet ray radiation emitted from high pressure metal vapor discharge lamp (6) at an energy level capable of deteriorating the samples in a short time, maintaining the samples in a temperature which can not be a cause of the deteriora- tion. According to the deterioration level, samples to be subjected to the weathering evaluation test are selected.
