Micom Laboratories is proud to announce that it now offers the ASTM D4355 test as part of its offering for polymer testing services. This standard details an accelerated weathering test which allows to assess the deterioration in tensile strength of geotextiles through the use of UV testing. Indeed, this method employs Xenon arc light as an illuminating source in order to characterize this property and it is thus based on the ASTM G155 standard.
ASTM D4355 Test
The main goal of ASTM D4355 is to assess the loss of mechanical properties of a geotextile material through the use of Xenon arc light as an illuminating source. In fact, this standard allows to investigate the effects of multiple factors that are associated with the studied material end use conditions by exposing it to an accelerated weathering test. Indeed, the deterioration that is due to the effects of heat, humidity and solar radiation is at the core of this method. However, the decaying that is caused by localized weather phenomena such as: biological attack and saltwater exposure is not taken into account by this test protocol. More specifically, this standard portrays the evolution of the tensile strength of the material through a deterioration curve that is obtained by evaluating the tensile strength of the sample at predetermined times. From this curve, it is possible to assess the tendency of the geotextile to decay when it is exposed to the test factors. Also, it is necessary to determine an acceleration factor in order to project the performance of the material onto the field from the gathered data of the test.
