ASTM D 1148 describes a standard test method for rubber deterioration from exposure to light , heat, and UV radiation. The test method involves exposing rubber samples to light, heat, and humidity in an accelerated weathering tester for a specified period. The tester typically uses a xenon arc lamp that simulates the spectral distribution of natural sunlight. The specimens are exposed to the lamp at an elevated temperature and humidity level, with periodic spraying of water to simulate rain.

Working Principle of Accelerated Weathering Tester: The WEW-ASTM-D-1148-UV accelerated weathering tester simulates ultraviolet radiation at a specified time to test the material’s resistance to ultraviolet aging. This Wewon accelerated weathering tester conforms to ASTM-D1148 standard. The accelerated aging tester simulates the transportation container environment exposed to sunlight to observe the degree of color resistance of the test products. It can be used as a reference for scientific researchers to prepare product materials and prepare chemical raw materials.

The lamp tube type accelerated weathering tester is mainly used for testing the yellowing resistance degree of light-colored and white materials such as upper material and bottom material of shoes exposed to sunlight. According to the light color or white products in the natural sunlight for a long time under the irradiation prone to yellow color phenomenon. By simulating the natural environment with a solar bulb or a lamp tube and a heating and temperature-controlling device, the surface color changes of the sample are observed within a specified time to determine the degree of color change of the test sample.

The exposure conditions specified in ASTM D 1148 are designed to simulate outdoor exposure in temperate zones. However, exposure times in the test method may need to be modified to suit specific applications or target regions. Also, the test has specific requirements for specimen preparation, including conditioning of the samples at a specified temperature and humidity level prior to exposure. It is essential to follow these preparation requirements and the testing standard to ensure accurate and reproducible test results.
