ASTM D4355

ASTM D4355 is a standard test method for deterioration of geotextiles by exposure to light, moisture and heat in xenon arc type apparatus. This test describes the determination of the deterioration in tensile strength of any permeable textile material employed with earth, foundation, soil, rock and so on. It is based on practice ASTM G155. Micom offers ASTM D4355 testing as part of its polymer test services.

Deterioration of geotextiles

By exposing the samples to xenon arc radiation, moisture and heat (end use conditions), it is intended to induce property changes. Indeed, polymers can have their mechanical, electrical and optical properties significantly altered when exposed to these types of factors. The simulation of the deterioration provoked by localized weather, such as, atmospheric pollution, biological attack and salt water exposure is not intended by the exposure used in this practice. Following each exposure period, the specimens are subjected to a cut or ravel strip tensile test in order to produce a degradation curve. The latter allows the user to determine the tendency of a geotextile material 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.
