The ASTM D4833 test method determines the index value of the puncture resistance of geomembranes, geotextiles, and related materials. A universal testing machine (tensile/compressive testing) can be utilized to meet the requirements of this specification. The test specimen is clamped between two plates of a ring clamp while a force is exerted against the center of the geomembrane by a steel rod until rupture occurs. Often materials that are tested on ASTM D4833 are also analyzed to D76, a specification for using tensile testing machines on textiles.
Before conducting ASTM D4833, it is important to read the entire specification in the relevant ASTM publication.
