DIN EN 13251:2015-07

This European Standard specifies the most important characteristics of geotextiles and geotextile-related products used in the construction of earthworks, foundations and retaining structures, and the appropriate test methods to determine these characteristics. The intended use of these geotextiles or geotextile-related products is to fulfil one or more of the following functions: filtration, separation and reinforcement. The separation function will always occur in conjunction with filtration or reinforcement, and hence will not be specified alone. This European Standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318. This European Standard provides for the assessment and verification of constancy of performance of the product to this European Standard and for factory production control procedures. This standard contains Amendment A1 which was accepted by CEN on 2014-12-13. This document has been prepared by Technical Committee CEN/TC 189 "Geosynthetics" (secretariat: NBN). The responsible German standardization committee is Working Committee NA 131-04-08 AA "Installationskomponenten" ("Installation components") at the DIN Standards Committee Aerospace (NL).
