Standard Test Method for Fluorescent (UV) Ultraviolet Lamp Apparatus Exposure of Plastics

The test method explains the test conditions and test procedures that are applicable for fluorescent UV exposure of plastics that are conducted in accordance with various test practices. The test method covers the preparation of test sample, test conditions that are suitable for plastic and assessment of test results. The test is performed to measure the ability of plastic materials to resist deterioration of mechanical, electrical, optical and other related properties that are caused by the exposure of plastic materials to water, heat, and light which are important for many applications.
The test helps to analyze various changes in properties related with end-use conditions, including the effects of moisture, solar ultraviolet irradiance, heat, and humidity.
