This document specifies a method for the determination of the puncture resistance by measuring the force required to push a flat-ended plunger through geosynthetics. The test is normally carried out on dry specimens conditioned in the specified atmosphere. The test is applicable to most types of geosynthetic products, but does not apply to products with apertures greater than 10 mm.
Abstract
Overview
EN specifies a standardized method for determining the static puncture resistance of geosynthetics using the CBR (California Bearing Ratio) test. Published by CEN and adopting , this standard is crucial for evaluating the mechanical robustness of geosynthetic products by measuring the force required for a flat-ended plunger to penetrate the material. The procedure is generally conducted on dry specimens that have been conditioned under specified atmospheric conditions to ensure consistent and reproducible results. The method is suitable for most geosynthetic product types, except those with apertures larger than 10 mm.
