Geotextiles and geotextile-related products. Screening test methods for determining the resistance to acid and alkaline liquids
59.080.70 - Geotextiles
EN ISO 12960
This document specifies methods for screening the resistance of
geotextile and geotextile-related products to liquids while not
subjecting them to external mechanical stress.
It is applicable to all geotextiles and geotextile-related
products. Method A applies particularly to polyamides and method B
to polyesters and polyamides. The test results are intended to be
interpreted in the context of site conditions.
This document is intended to be used in conjunction with ISO/TS 13434.
This document only considers conditions where the specimens
are fully immersed in the liquids. Though outside the scope of
this document, the test conditions can be modified to accommodate
particular applications, e.g. gaseous media. This document does
not preclude use for test specimens that are pre-treated by some
method, e.g. by weathering, aqueous extraction conditions or
