This standard BS EN ISO 12236:2026 Geosynthetics. Static puncture test (CBR test) is classified in these ICS categories:

• 59.080.70 Geotextiles

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.
