This Standard sets out the method for determining the burst strength and deformation properties of geotextiles using the California bearing ratio (CBR) test apparatus for both atmospheric-conditioned and wet-conditioned specimens.*

* This method is based on DIN 54307, Testing of textiles; plunger puncture test (CBR). The equipment has been a modified to allow the use of a CBR mould that would normally be available in soil-testing laboratories.
