CREDONICS universal testing systems equipped with a puncture test fixture are capable of determining the puncture resistance of materials such as plastics, films, fabrics, geomembranes, and related products. Puncture testing primarily involves tear and stiffness and measures the resistance of a test specimen to puncture. CREDONICS offers a selection of puncture fixtures with varying probe and clamp sizes designed according to many ASTM and ISO test standards.

Common puncture testing definitions and keywords include :

Puncture resistance : The resisting force to penetration or puncture. Puncture resistance measurements are expressed in force units.
Puncture strength : The maximum stress a specimen can withstand before it exhibits failure by a penetrating or puncturing object. Puncture strength measurements are expressed in force per unit area.

Common puncture testing standards include :

ASTM D4833 – Standard Test Method for Index Puncture Resistance of Geomembranes and Related Products
ASTM D5748 – Standard Test Method for Protrusion Puncture Resistance of Stretch Wrap Film
ASTM D6241 – Standard Test Method for Static Puncture Strength of Geotextiles and Geotextile-Related Products Using a 50-mm Probe
ASTM F1306 – Standard Test Method for Slow Rate Penetration Resistance of Flexible Barrier Films and Laminates
TSO-C69c – Test Method for Emergency Evacuation Slides, Ramps, Ramps/Slides, and Slide/Rafts
