ASTM D4355 是土工织物暴露在光线下劣化的标准测试方法, 水分, and heat in xenon arc type equipment. This test describes the determination of tensile strength degradation of any permeable textile material used for soil, foundation, 土壤, 岩石, ETC. It is based on ASTM G155 practices.

Deterioration of geotextiles

By exposing the sample to xenon arc radiation, 湿气和热量 (end-use conditions), it is intended to cause property changes. 实际上, when exposed to these types of factors, polymers can have significantly altered mechanical, 电气, and optical properties. Localized weather-induced deterioration simulations, 比如大气污染, 生物攻击, and saline exposure, are not expected by the exposures used in this practice. After each exposure period, the sample is cut or stretched strip stretched to produce a degradation curve. The latter allows users to determine the tendency of geotextile materials to deteriorate when exposed to various factors such as solar radiation, water and heat. For a combination of UV exposure and salt water, you should consider ASTM D5894.
