Now you can download the ASTM D4355-D4355M-14(2018) pdf here.The size of this pdf file is 2.13M.The title is Standard Test Method for Deterioration of Geotextiles by Exposure to Light, Moisture and Heat in a Xenon Arc-Type Apparatus.
This 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 light source.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
ASTM D4355-D4355M-14(2018) is intended to induce property changes associated with end-use conditions, including the effects of solar radiation, moisture, and heat. The exposure used is not intended to simulate the deterioration caused by localized weather phenomena such as atmospheric pollution, biological attack, and salt water exposure.
If it becomes necessary for the purchaser and seller to use this test method for acceptance testing, the statistical bias, if any, between the purchaser’s and seller’s laboratories should be determined. Such comparison is based on specimens randomly drawn from the sample of geotextile being evaluated.
