ISO 22182-2020 pdf download.Geotextiles and geotextile-related products – Determination of index abrasion resistance characteristics under wet conditions for hydraulic applications. This document specifies a test method for determining the abrasion resistance of geotextiles and geotextile-related products under wet conditions. This document is applicable to geotextiles and geotextile-related products intended to be used as e.g. geo bags or filter beneath armourstone. The test method simulates abrasion impacts on geotextiles and geotextile-related products such as that caused by the movement of rocks in an embankment or transport of sediment in rivers. This document provides an index test which can be used for performance and acceptance testing. It can be used as performance test by comparison of mechanical and/or additional hydraulic properties before and after abrasion impact. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
