Geosynthetics - Static puncture test (CBR test) (ISO 12236:2026)
This document specifies a method for determining the penetration resistance by measuring the force required to push a blunt punch through geosynthetics. The test is usually performed with dry samples that have been conditioned in the specified climate. The test is applicable to most geosynthetic products, but does not apply to products with openings larger than 10 mm.
