ISO 13438:2018

This document specifies a screening test method for determining the resistance of geotextiles and geotextile-related products to oxidation. The test is applicable to products as follows:
-  Method A for material consisting solely in polypropylene (PP), polyethylene (PE), polyamide (PA), aramide (AR);
-  Method B for material consisting solely in polyvinyl alcohol (PVAL).
The data are suitable for screening purposes but not for deriving performance data such as lifetime, unless supported by further evidence.
