Technical rule [CURRENT]
This Technical Specification describes a laboratory procedure for the rapid testing of the resistance of polymeric, bituminous or clay geosynthetic barriers to root penetration. It is suitable for testing welded seams or other areas of potential weakness. A longer test that may be more suitable for testing the long-term resistance of geosynthetic barriers is described in EN 13948. The body responsible for this DIN CEN/TS is NA 106-01-11 AA "Geotextilien und Geokunststoffe; SpA zu CEN/TC 189 und ISO/TC 221" ("Geotextiles and geosynthetics; mirror committee to CEN/TC 189 and ISO/TC 221") at DIN.
