Puncture Fixture for ASTM D4833 Geomembrane Testing

Puncture test fixture to test index puncture resistance of geomembranes, geotextiles and related materials to ASTM-D4833. During the test, the specimen is secured between two plates of a ring clamp, and a probe applies force to the center of the geomembrane until it ruptures. The fixture works with a universal testing machine to record the force and displacement during the test. This ensures geomembranes meet quality standards for applications like landfill liners, containment systems, etc. This fixture is designed to mount on a standard 5/8" eye end. This connection type is commonly used on Lloyd Instruments, Chatillon, and Mark-10 equipment. We also sell these brands of test stands, load cells, and force gauges to use with our grips and fixtures. Adapters are available to accommodate other connection types and sizes.
