ASTM D4833 – Puncture Resistance of Geomembranes and Related Products

To request a quotation for any test email for a prompt reply

ASTM D4833 is used as an index test for determining the puncture resistance of Geomembranes. This test can be used as acceptance criteria testing of commercial shipments of Geomembranes and related materials.

A test specimen is clamped without tension between circular plates of a ring clamp attachment secured in a tensile testing machine. A force is exerted against the center of the unsupported portion of the test specimen by a solid steel rod attached to the load indicator until rupture of the specimen occurs. The maximum force recorded is the value of the puncture resistance of the specimen.
