This standard BS EN ISO 12236:2006 Geosynthetics. Static puncture test (CBR test) is classified in these ICS categories:
59.080.70 Geotextiles
This International Standard 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 products, but not to materials with apertures greater than 10 mm.
