Standard Test Method for Deterioration of Geotextiles by Exposure to Light,
Moisture and Heat in a Xenon Arc Type Apparatus

X-TEX LogoThis test method covers the determination of the deterioration in tensile strength of geotextiles by exposure to Xenon arc radiation, moisture, and heat.  The light and water exposure apparatus employs a xenon-arc source producing the most realistic simulation of full spectrum sunlight including UV, visible and infrared wavelengths. The test is run for 500 hrs using the “Triple Threat” of light, temperature, and moisture. The short-wave UV is the cause of most polymer degradation, the controlled high temperature accelerates the photochemical reactions, and the moisture erodes degradation by-products allowing fresh surfaces to be exposed. After the exposure period the textile is tested for tensile strength and compared to the pre-testing tensile strength. The result is expressed as a percent of retained tensile strength.  Values over 70% retained strength are considered good for geo-textiles. The X-Tex fabric has average retained values over 87% which is excellent for outdoor weather exposure.
