ISO 12960-2020 土工织物和土工织物相关产品--测定耐酸和碱性液体的筛选试验方法 Geotextiles and geotextile-related products-- Screening test methods for determining the resistance to acid and alkaline liquids

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.
NOTE 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 installation damage.st edition 2020-05 Geotextiles and geotextile-related products — Screening test methods for determining the resistance to acid and alkaline liquids Géotextiles et produits apparentés — Méthodes d'essai sélectives pour la détermination de la résistance aux liquides acides et alcalins Reference number ISO 12960:2020(E) ？ ISO 2020 ISO 12960:2020(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO
