After each exposure cycle, the specimen is subjected to a cutting or tensile test strip tensile test. Compare the average breaking strength in each direction with the average breaking strength in each direction of the reference. The percentage of retained specimen strength relative to exposure time was plotted to obtain the tensile strength curve of samples from each direction.
Xenon Arc Test Chamber Used
1. The ASTM D4355 test method covers the determination of the tensile strength reduction of geotextiles caused by exposure to xenon arc radiation, moisture, and heat.
2. The lighting and water exposure equipment uses a xenon arc lamp and a water sprinkler system.
